How To Fit Larger Tires on Your Chevy Silverado or GMC Sierra

How To Fit Larger Tires on Your Chevy Silverado or GMC Sierra


Hey, guys. Adam here with americantrucks.com and on this
episode of the haul, we’re going to take a look at three different tire sizes, comparing
contrasting them talking about their pros and cons. And then I’m gonna give you my best recommendation
as to how to fit these popular tire sizes with some of the most popular lift kits. Now the three trucks behind me are my 2016
Silverado LT completely bone-stock off the factory line with stock 31-inch tires. Next to that is a 2014 Silverado LTZ sitting
on a rough country 3.75-inch suspension and body lift and 33-inch tires. Finally, on the end, there is a 2011 Sierra
with a 7.5-inch suspension and body lift combo with 35-inch tires. I’m also gonna take that 2014 out with the
33s for a driving experience test to see how it feels on the road, give you my thoughts
and concerns about it. And then I’m gonna throw the 35s on and show
you how the fitment issues can arise when you put those big tires on such a small lift. Now before we get into all that, we got a
lot of juicy content for this video. Make sure you subscribe to our YouTube channel

tire from the 2016 Silverado LT. Now, this one right here is going to be one
of the many options you get off the factory line for your Silverado. They do range a little bit in tire size and
wheel size but ultimately the characteristics will stay the same across the board. Now this one here is a 255-7017 Bridgestone
dueler HT tire. It’s an all-season tire. Now it comes standard on a lot of light to
medium trucks even SUVs and jeeps because it stays quiet on the road which is one of
the most important factors. It’s comfortable, it provides decent traction
and some pretty good fuel economy. Now like I said the different measurements
will range from the different trim levels ultimately up to 80 to 85, at 4522 but again
those characteristics do remain the same. The sidewall here is a little bit shorter
than most aftermarket wheels which eliminates some of that squishy or ballsy feeling you
get while daily driving, which is definitely a bonus in my opinion. Now if you’re into keeping your truck all
original, you like the factory set up, this is a perfectly satisfactory tire. Now with that said, I put about 15,000 miles
on this exact tire here and I’ve got absolutely no complaints. Now the wheel itself is a 17 inch by 8-inch
wide wheel with a plus 24-millimeter offset. Now that positive 24-millimeter offset refers
to the distance from the hub mounting service to the centerline of the wheel. Now it’s pushing out plus 24, positive 24
millimeters to the outside of the truck which ultimately has the tires sit in a little bit
farther into the wheel well toward the frame. Now once you start going with the aftermarket
wheels with a bigger and wider setup, that offset ultimately will change. Now moving on to our first set of aftermarket
wheels and tires, arguably one of the most popular wheel upgrades to 33s. Now, this particular tire is a NATO mud grappler
and as the name suggests, it’s a mud to retire. This will definitely serve a bigger purpose
for those off-roaders for hitting the trails going in a lot of mud and looking for maximum
traction because these are one of the nubbiest tires on the site currently. These will perform far better than the stock
31s which weren’t terrible off road but obviously, they are gonna lack in the traction department. Now, these 33s are wrapped around a 17 inch
by 81/2 inch wide matte black fuel and a wheel. Obviously, they look pretty cool but the more
important factor here is the size. They are a half inch wider than the factory
rims and of course, the two inches of additional tread and sidewall of the 33s over the 31s
will add some bulk to it as well. Now the offset for these is a negative six
millimeter which obviously means the center line or the center hub will sit six millimeters
back towards the inside of the truck which pushes the wheel out to the outside. Basically the complete opposite of the stock
wheels. Now that will result in some noticeable polk
which basically means the wheel is going to stick out past the fender wells poking out
just about a couple of inches. Now the big thing to remember with the 33s
is that, when you try to put these on a stock height or a stock suspension with no lift
whatsoever, there will be some rubbing on your stock components. Now what you’ll need to do to make 33s work,
and what we found out by testing it on my 2016 Silverado, is that with at least two
inches of leveling kit or a lift kit on the front end, you’ll get enough clearance to
make things work without rubbing when you’re at full lock or full turn. Now we found that they will rub on the stock
components without that. So we threw it on our 2014 Silverado with
a 3.75-inch lift which gave us the perfect amount of gap and the perfect amount of spacing
to make them work with no modifications needed. Now the last thing I want to touch on which
is kind of a downfall, in my opinion, is the fact that the mud terrain tires we have here
will be pretty noisy on the road. If you’re using your truck as a daily driver
the mud terrain wouldn’t exactly be my recommendation. So if you want the best of both worlds, you
want on the road quiet and comfortable ride but you also want a little bit off-road performance
with better traction and a more aggressive tread pattern, you can go in between the two
and get an all-terrain such as a Mickey Thompson A.T.C. Now moving on to our last but not least 35-inch
tire. This is obviously the biggest one we have
out here and arguably the hardest one to fit on these different Silverado is in Sierras. Thanks to the square wheel well which kind
of limits the ability to fit these bigger tires. If you want to fit 35s, you need at least
a 6-inch lift. Now we decided that it wasn’t gonna fit on
our 2014 Silverado with the 3.75-inch lift. So we decided to throw this on a 2011 Sierra
with that 7 and a 1/2 inch lift I mentioned earlier. That truck is sitting on a rough country 6
inch suspension lift, it’s got two inch life blocks and adjustable front struts from Eibach
which equal out to a combined 7 and a 1/2 inch lift. Now when we threw these 35s on that truck,
it still had some rubbing, believe it or not. Like I said, you’ll need at least 6 inches
of lift and with that added 2 and a 1/2 inches on top of that, it still had some rubbing. So we went ahead to made a little bit of modifications
to make it work. Now, originally it was rubbing on the lower
valence under the front bumper as well as a little bit inside the wheel well. So we cut away just a small amount of that
trim spoiler and we also shaved away some of that inner wheel well and now there’s absolutely
no rubbing at all and it’s perfectly suitable for the road. So if you’re looking to fit the 35 like this
one, obviously the exact same tire as a 33 is just two inches taller, this is gonna require
that 6 inch or more lift kit with very minor modifications. I definitely wanna point out that for the
33s and 35s, we use the exact same type of tire, exact same tread, exact same wheel on
the seam offset. That way we can keep the tire comparison pretty
equal across the board. Only difference here is that the 35s are a
bit bigger and they do cause a little bit more fitting issues. And the general rule of thumb is with 35s,
the lower you go with your lifts the more modifications necessary to make them work. Now that we’ve broken down the three different
tire sizes, why don’t we take our 2014 out with a 3.75-inch lift and the 33-inch tires,
see how it performs on the road, kind of give it a real-life driving test for all your daily
drivers out there. We’ll also talk about the benefits for off-roading. So let’s get to it. It feels pretty good. I don’t feel like I’m riding on mud terrain
tires. I will say I can hear it. I don’t know if you guys can hear that or
I’ll shut up for a second so you can listen. It’s kinda like a humming noise. You can hear the humming noise. It’s not overwhelming but it definitely is
noticeable. On the highway at higher speeds, it’ll get
a little louder but it’s definitely still not too bad. If you want to eliminate that, all-terrain
tires are the better choice. They’re quieter, they still have a little
bit of a nub there to give you some added traction off-road. They’re still pretty beneficial. I did notice that it was a little sluggish. Obviously, that’s gonna happen. You’ve got those bigger, heavier tires, wider
tires you’re kind of lugging around plus it’s got the nubby mud terrain tire tread. So that’s gonna add a little bit of resistance
to it, I guess you could say. What you are going to make up for in that
downfall is off-road performance for one. When you get off road, not only are you getting
added clearance with the lift, you’re adding two inches of tire under your suspension. So when you add that, you’re actually going
to get more offroad clearance. You’ll see you’re going over logs or, you
know, smaller rocks or whatever. Just a little bit easier because those stock
31s just they don’t have number one traction and they don’t have the height clearance,
you know, to get over things. Now as far as looks go, obviously, everybody
has different preferences. The 33s I think do look pretty bad ass and
they’re just an easier route to take. So you throw the 33s on a lift like this and
you’re hitting the road, you’re hitting the trails, and you’re good to go. Now the wheel that you pick you obviously
want to take into consideration which offset you’re using. The offset that we have here of the minus
six or the negative six-millimeter offset was perfect for our situation. That little bit of polk that sticks out of
the fenders and gives us some interior clearance so that when we are at full lock or full left
turn or full right turn. The inside of the wheel isn’t hitting control
arms or leaf springs or anything like that. I have a full turn here and I’m gonna go full
lock and no rubbing whatsoever. Now when you upgrade to 33s like this, it’s
hassle-free. I mean especially with this kind of lift,
you want to at least make sure you’re getting a… I would say a safe bet would be a two-inch
leveling kit up front or a lift kit all around, that way you’re guaranteed to clear all of
this and not require any modifications. So without me babbling on any more about the
33s, why don’t we take this back to the shop. We’re gonna throw the 35s on this, I’m gonna
show you exactly how much clearance issues will be caused by adding such a big tire to
a lift like a 3.75. So let’s get back to the shop and get those
on. We are loaded up in my 2014, 3.75-inch lift
with 35s. On the 35s driving is completely straight,
on this lift no rubbing at all. What you can hear, however, wow, that’s loud. Same exact tires. I wanna point out that these aren’t nubbier
than the 33s, they’re the exact same tire. So what I’m gonna do here is, I’m gonna make
a left at this light and see how it handles this. It’s not gonna be full lock but it’s gonna
be pretty close, I think. That handled pretty well. I have another turn coming up here that will
probably be full lock. There it is. It’s actually resisting the steering wheel,
I can’t even accelerate because the nubs on the tire are just catching the chin spoiler. The same thing happens to the wheel well,
it rubs so hard in the wheel well that it actually slows your acceleration down. I’m surprised we made it out of the parking
lot. So it is doing better than I imagined. I thought it was going to be tough to even
make a small turn. So 35s on a 3.75-inch lift requires modifications,
hands down period. No questions asked with this setup. Even if you’re going off-roading, you gotta
get yourself in these weird angles on rocks. Now the 35s will give you definitely a good
functionality benefit in performance benefit off-road because you’ll be able to tackle
even bigger obstacles than the 33s would especially with the bigger lift, still have a great off-road
performing truck. But if you put these on a truck that, you
know, they don’t really fit properly on, you’re gonna have a very uncomfortable ride. Turning back into the parking lot here you
just heard that rub again. So this gets to a point where it’s so continuous
it’s gonna wear down everything it’s rubbing and it’s going to become a pretty serious
issue. As you can see, 35s can be tricky to fit under
these square wheel wells on the Silverado and Sierras. Some modification is necessary above six inches
of lift, under that they can get even hairier. Thirty threes are a lot easier to handle. Of course, anything from two inches on with
lifts will make these happen with no modifications and stock pretty self-explanatory. Make sure you subscribe to our You Tube channel

  1. youre supposed to change your differential ratio if you put 35" tires on it. nobody does that but if you do it will help with mpg losses and you wont lose power that you lose by adding bigger tires. if youre going to be on pave most the time dont put knobby tires on it bc youre idiot if you do. pretty trucks with knobbys that rarely in dirt are for pussys. my truck isnt supposed to look pretty its supposed to be manly. side note. running knobby on pavement is a waste of money and rubber and mpg so just dont it fags.

  2. when youre talking about american trucks does it mean a Tundra or do you mean mexican-canadian trucks like chevy? hmnn im confused

  3. I have a 06 Chevy 2500hd with a 2.5 inch life with 35’s they really do not rub that much, the front bumper plastic had to be cut about half an inch and now they don’t rub the front, on the back of the wheel well when you put stress on the suspension then you will have a little rub. So yes you can put 35’s on a small lift.

  4. On my 2010 Ford F-150 I run on my stock wheels a 285/75r18 Toyo Open Country AT2 which is roughly 35”x11” on just a 2” leveling kit and never had any issues with the tires rubbing at full lock

  5. You just helped a 15 year old find mods for his future truck, o'l blue, o'l blue was grandpa's 85 chevy silverado, and he sold her, she was my fav truck, but I'm gonna get a blue k20 or a silverado of that exact year

  6. Thanks for this video! I plan on buying that exact Rough Country 7.5” suspension lift for my 2014 work truck with some 35” tires (haven’t decided what brand yet)

  7. When you get tires that are 2 inches bigger in diameter, you add only 1 inch to the height of the truck. You said 2.

  8. 2014+ can take 33×12.5xR17 on stock wheels no rubbing. Can even fit on 0 offset 8×17 inch wheels with no rubbing. And using those wheels you will need less than 6 inch lift for 35's. You shouldnt use the term wheel interchangably between tire and rim. A wheel is not a tire like you call the dueller h/t's.

  9. I just put a 2.5" level on my 17 Silverado. If I was to get larger wheels/tires what would be the best choice for me? I was going to buy regular rims to put on my stock tires but didn't know if I could put a larger tire on a 17×8 rim. Thanks for the help anyone.

  10. I’d like to see the white truck with 33s on it. Don’t need a drive, just a look. Have you ever done this and have pictures?

  11. I did the 3in level kit and had 20×10 -24 offset and mine fit just fine. I did have to trim a little bit of plastic but they fit

  12. I maybe childish for asking but I plan getting a 6-7in lift and wanna run 33s with 20×9 or 20×10 cause really I like the stance. Please reply with personal opinions!

  13. Could you fit 33s on a 20×10 on stock 2014 sierra with 2in level would that make a combined 5in higher than stock?

  14. Them square wheel wells make it way harder to fit big tires and they all look like the tires are too small

  15. I'm going down size to 33 from 35 for road trips . Keep the 35 around for the monthly camping trips but for daily driven I'm looking at 285 or 33 . I'm going be two tire man ! V ! 2

  16. Go ford I could fit 35s on my 2010 with just a 2 inch leveling kit suck it Chevy and gmc lol

  17. Great video. Can you do a similar one with using a 2017 jeep grand cherokee with the leveling suspension. What's the largest tire (33") can you use stock.

  18. I’m running a 2.5” leveling kit with 285/75/17 terra grapplers on a 2010 Sierra ..no issues, little rub when in reverse ..nothing major though..looks awesome for a daily driver

  19. I don’t like leveling or lift kits.

    What’s the biggest tire can you put on the 2014 Silverado with out a lift kit or leveling kit.

  20. U can fit 33s with no lift. Just leveling kit. That 4 inch should be able to fit 35s and the 7 inch could easily fit 37s

  21. The stock truck looks fucking puny. Stock chevys are so damn lame they sit too low

  22. Half tons are gay lol I know I guy with a 2014 f250 who fit 37s with a 4 inch lift. Heavy duty's where its at boyz

  23. So moral of the story is that you need a lift kit of some sort to put bigger tires on the stock 31 inch tires that come on a Silverado.

  24. Great video.can I put 265/70/17R.on my 2006 GMC 1500 Sierra my Stock tires are 245/70/17 R ?

  25. Btw there’s no such thing as a suspension body lift combo. 2 completely different things. You get either or not both lol

  26. How about a stock diameter 31" tire but wider and offset outwards ?
    I commute with my '08 Sierra 4×4 to work and pull a 29' 5th wheel toy hauler.
    I want the look but don't want to kill the utility of the truck.
    I have already installed a Rough Country leveling kit in the front and 3" fender extensions.
    Any ideas??

  27. Suspension/body lift combo??? Wtf? This guy cracks me up. Go back to school, learn what the shit is before you make videos misinforming people. Lmfao n smdh

  28. ok, I could use some advice
    I have a 2017 F-150 that came with 17 in wheels and the tires are 245 70
    The easy change would be to get the Ford 20 in wheels that come on the STX model

    Most of the tires I see in 20 in are just 50 or 60 series
    Why is that

    Also, how do I find the Offset and Back Spacing on my Factory 17 in wheels?
    This is critical as I want to change the Offset negative 1 to 1.5 inches or so
    This will let the new wheel be that much wider

    Also, how can you learn how much Back Spacing vs Offset you can have on your truck without
    getting a rub at wheel lock without buying a wheel for test fit

    James

  29. Great job so I got 2002 GMC Envoy I have a suspension lift think about a body lift have a 3in suspension lift and I have ko2 tires but I want to get Big O Tires in the front so I had to do mine a modification so with bigger tires I haven't even have to make even more modification put great job on your videos

  30. I have a 2011 GMC Sierra Denali with a 3.5” lift have stock Denali wheels with 35 Nitto Trail grapplers. (Trail Grapplers people)

  31. I have a 2014 sierra crew cab with a 2 inch level. I just put on 305 55 R20 with 20X9 wheels. They fit great with very slight rub at full lock turn. However I was told that my ball joints will need replacement because of the 33s. Should I get new control arms?

  32. Your installing a bigger tire. But your rims. R wack. They look like honda civic rims wack wAck. Next time try 20×12 or 14

  33. my son-in-law thought he could drive 70 mph with snow chains. Now he can add 35's without any additional modifications.

  34. I’ve got a 2001 f150 4×4 and can fit 35 on stock suspension and 12 wides with 33 with no scrub at all

  35. HAHA yeah those 31's can't get over logs but the bigger by 1 inch 33's can get over a log because of the massive clearance lol. 37's and up are real tires

  36. idk why chevy made their trucks incompatible with larger wheels when they KNOW its a popular thing people do. Ford and Jeep make their vehicles large tire friendly without chopping and lifting….

  37. Now. How about the 33's on a 2500HD stock suspension. Would the rub against the fender or not? 2500HD suspension its higher than the normal 1500.
