The Basics of Wheel Fitment

The Basics of Wheel Fitment

– What’s goin’ on, guys? It’s Alex from Fitment Industries, and today, we’re going to be
talking to you about fitments. So, one thing you guys may have noticed is that all of our videos, all the things we’ve been
trying to show you on Facebook, or on our website, is trying to get you to get the perfect to get
the perfect Fitment setup on your vehicle. Well, sometimes, people
just don’t understand what fitment is. We were all there once. Not all of us are experts
in the wheel fitment game. So, when we get into fitment, the first thing that we
just want to talk about is the overall basics of a wheel. So, when we talk about
bolt pattern, or hub bore, the diameter, or the width of the wheel, all of these things end
up making what fitment ultimately is on your car. And it’s also rims and tires. We’re simply going to be
talking about (beep) today, but we will be talking a
little be about tires as well as we go through this. So, if you’re looking to get started into getting the perfect
fitment on your car, you’re gonna want to learn first just about your setup on your car. So, what is the bolt
pattern that you have? You’re gonna want to make sure that you get the right bolt
pattern just to start off. So, once you figure out
what your bolt pattern is, you’re also gonna want to know, or at least keep in mind
of what your hub bore is. So, your hub bore is the size of your hub. Your hub would be this center piece, the actual inside, not the plastic cap. You’d be able to measure
that using a tool yourself. Usually, that is measured in millimeters. So, a lot of after market
wheels are gonna have a larger hub bore than what your factory vehicle’s gonna have. And they do that on purpose. They wanna make sure that
those wheels will fit your car. If your after market wheel
has a smaller hub bore than what your vehicle allows, you are going to experience that some things simply will not fit. So make sure you’re keeping an eye on that when you’re buying wheels and tires. Another thing that they can come with, with hub bore, you can get adapters. So, something that if
your aftermarket wheel is going to have a larger hub bore than what the vehicle has, you can get adapters to help
make sure those fit and snug. Hub bore helps, especially
when you get the right sizing, to minimize any sort of vibration and just overall drive quality of your after market wheels on your car. The most important thing you guys probably think is diameter. And, we’ve gotten really
accustomed to getting huge wheels on these cars. But something to remember is that if you’re looking to modify an older car, you don’t just want to
get a huge, wide wheel, a tall diameter wheel,
just because you can. You’re gonna want to make
sure you keep in mind just how the overall
wheel is going to look, and that’s where diameter
really starts to play a role. Not all wheels are the
17 inch sizing anymore. A lot of them are coming standard in 18, or even 19 inch sizing. But, you’re gonna want to
make sure you do something that’s called sizing up. You can actually take a look
on your stock wheels and tires what the actual diameter and width is, and then looking at what
your tire aspect ratio is, and overall diameter, you can go up a size in a
wheel from maybe a 17 to a 18, if you downsize the
actual size of your tire to maybe a 235/45, to a 235/35. And that will allow you
to actually maintain the same overall diameter of your wheel setup that you have stocked to after market wheels and tires. If you continue to up-size,
which you definitely can, You’re ultimately gonna reach a max, then it’s just gonna look like you have rubber bands on your rims, and that’s just not
gonna look good at all. If you’re ending up and getting diameter and you’re not caring about width, that’s bad. Something to make sure
that you’re keeping in mind is your overall wheel width. So, if you’re taking a look at upgrading to maybe a 9 inch, or 9 and 1/2, that you have the clearance for it. So, something that you can do, is you can actually measure
the space from your tire on your stock vehicle to the nearest potentially protruding object, like maybe you have your perches, or your suspension components,
or something like that, and see how much space
you have to play with. On our website specifically, we take care of all of that for you,
so you can make sure that you’re not going to have
any issues with clearance. But, if you want to double check and make sure you’re doing it right, you can actually go there,
you can measure the distance, and then multiply that by two
because you have to remember that the wheel will be going
wider in both directions. So, if you have, let’s say,
an inch of clearance space, you would actually be able
to go two inches wider if you really want to
play it aggressively. But you’re gonna have to remember to take into consideration
like 1/8 to 1/4 of variance, you have to think about tires, if the tires are gonna
stretch, or anything like that. Another thing that’s
really going to help you is understanding what offset is. Offset is going to be what really makes one of the biggest differences between how a wheel looks, and how a wheel is going to
perform actually on your car. There’s a couple different things that you can really consider with offset. You have positive offset,
negative offset, and zero offset. Starting off, positive offset is gonna be when the face of the wheel extends to the outboard side of the rim. It’s gonna tuck the wheel underneath further into the wheel well, and you can actually experience
some clearance issues. Negative offset is when
the center piece here is going to be sitting farther back in the actual wheel, and
it’s going to protrude out towards the fenders. So when you get closer
to zero, you’re going to experience usually more lip,
you’re going to experience potentially clearance
issues with your fenders, or rolling and things like that, but most people try to go down an offset to give it a more aggressive look. Zero offset is just gonna be
where you’re gonna want to sit if you’re looking for a
race, after market purpose. And that’s just gonna be
directly with your center line, which is pretty much just perfect bliss. But something to keep note, is that if you go too far into negative offset, you are going to experience
just as many issues as you would as if you
had positive offset. It’s always a range with
how you’re going to set up the fitment of your vehicle, and all this stuff makes the difference when you apply your rim and
tire into your wheel well, making sure that it fits properly. Fitment is all of those things. It’s taking into consideration everything that makes a wheel a wheel. And making sure that it lines up with what you want on the vehicle, and what the vehicle will actually allow. Bidding that fitment perfect
is the difference between having a mediocre set up and
having an amazing set up. Because we truly believe that
if you have the right set up on your car, you will just fall in love with your car all over again. So that is what fitment is. It’s all of those things. We hope you guys enjoyed it. If you have questions on your fitment, let us know, shoot us an email. It’s Alex Fitment Inc. We’ll see you later. Peace! (upbeat music)

  1. "What Is a Wheel and What Is a Rim? Are They the Same Thing?
    It may seem obvious, but a wheel is comprised of a hub, spokes and rim. Sometimes these components will be one piece, sometimes two or three. The hub is the center portion of the wheel and is what attaches the wheel to the suspension. The spokes radiate out from the hub and attach to the rim. The rim is the outer part of the wheel that holds the tire. *While many people refer to wheels as "rims," this is technically incorrect.* We'll discuss several ways that wheels are manufactured below."


  2. Need some help from you guys I have a 2009 HONDA inspire the original rims are 17 but I want to go to 19 what you guys think??

  3. There should be a fitment 101 style page on your website. It would also help if the cars featured on the page had more specific specs on coilover setups/height, air ride setups, and degree of camber. That helps or can help some people get a better idea of what to achieve.

  4. I love these videos and this channel but honestly you need to stop using 40x40jpg images edited in (example @ 2:25+). We cant tell what they say, but if you really want them then make them only take up a corner of the screen so i can still watch the guy talk. 🙂

  5. Can i just say you're channel has helped me alot! Thank you for the detailed info and keep up the good work! Cheers.

  6. If you change from 235/45r17 to 235/35r18 then your tire will be 1 inch smaller.
    You would have to go from 235/45r17 to 225/40r18 to be similar. It will only be 0,2 inches smaller

  7. I'm planning to change my 215/65r15 tires to 215/55r17. I don't know if the new tire size will raise my car up or not.

  8. I added my car to your galley a while ago and just noticed that my offset on my wheels is incorrect. I had a custom offset made and it was rounded up to +30. Just wanted to fix that for people to see.

  9. For my 350z I plan on getting a set of 18×9.5 +22 and 18×10.5 +25 Volk G25s, with tire sizes: 255/35r18 for the front and 275/40r18 for the rear. I'm set on these wheels because I already have them, but I wanted to know if you guys had any input on my choice of tire size.

  10. bore, wheel diameter and width, bolt pattern, tire dim's, spacers and or adapters, camber plates, coilovers, centering plates, studs or bolts, frame notching, anti-sway bar relocation, ride height….so many details, but it's true love ♥

  11. What's a good size tire to use on a 15×8 rim to get that nice, subtle stretch look. I'm NOT trying to get that Sudani stretch look. lol. Right now I am using 165/50R15s on 15×6 and I like this look, but going up to 15×8… I've never done that before

  12. Hey Alex, hopefully you can help me, I'm trying to get a staggered set up for my car, I drive a 2010 ford fusion, 20×9+35 and 20×11+15… any idea if it will work..thanks in advance

  13. quick question bro, if im currently running 19×9 +40 all around, but i want to go 8.5f and 9.5r if i do +35f and 45r will i get the same fitment? im trying to buy some wheels for my q50 for i have that concern

  14. Just wana add to thoes who don't know why there is a positive offset from factory, it's becouse the factory want the wheelpressure to be straight over the wheelbearing.

  15. so if I like someones fitment, but I want different wheels, can I take their exact wheel size and tire size to a different wheel? im so confused by offset. it seems different depending on if the wheel is concave or not. ill find a picture of a fitment I like, but won't be able to afford the rims, so ill google rims I can afford that are the same size, but they look way different fitment wise? I got so confused when you posted that picture of the car with two different wheel setups, one car had double the offset of the other but the wheels fit exactly the same!!

  16. I always see what other people run, then buy wheels and tyres that are roughly similar in size, THEN modify the body to fit the wheels.

  17. when plus sizing, how does it effect the tire pressure you'll use on your tires? id like to plus size from 16" to 18" rims, and ive gotten a good tire size with the 1010tire calculator.
    still in the planning phase as far as rims go

  18. I’m trying to figure out my fitment for my 12’ Civic. I was thinking of going with 8.5-215/40/R17 (Offset Undecided) I would like it to poke a bit without much of a gap but to have the clearance it needs. Without needing to roll or cut preferably. This is my daily driver so I want to be safe, but also have the look of stretch. Thanks!

  19. Looking for help. I drive a 2014 Scion tC.
    Stock it's 18"x7.5"/ET +39mm/60.1mm Hub with 225/45R18 Tires
    Trying to bump up to 19"x9"/ET +25mm/60.1mm Hub with 255/40/R18 Tires.
    You guys think that'll fit?

  20. I have a 2012 GTI and I really like how the wide body cars look. What wheels and tires can I get to get that widebody look without having the tires hit the wall? I want to use fender flares as well. Can you please help me?😭🙏

  21. wow some of these cars look like the marshmellowman from ghostbusters stepped on them. the nsx looked decent though.

  22. The rim that you have right next to you what is that reason why I’m asking I’m a novice to this and I bought a G35 that came with that very same one but I noticed that the set to the rear has a deeper dish, i want to get a different set of rims with the same offset any advice?

  23. Awesome vid , subscribed , check this bad boy out and sub back if you can 🙂 !

  24. I’m new to all this. Am I able to put aftermarket rims/tires on stock springs? Will it fill in the open space it after I change it? Or would I have to get coil overs in order to fill in the gap?

  25. what if i go low on offset with spacer adapters and my tire sticks out of the fender and i like that setup, is that considered good fitment? I am not planning to go widebody yet. and i have factory camber with factory ride height (because i dont like slamming)

  26. With my SUV turbo gasoline which uses alot of gas, I want to change my 235/55r/18 to more narrow tire such as 215/40r/18 or a 225/40r/19”, but many say oh no,no,no, because the speedometer and odometer. But Should I really care about those when I just want to save gas and have a low cool fitment

  27. I have a Toyota RAV4 2003 (2nd generation) 4×4 SUV. The stock wheels are 16" x 7" alloy rims with 235/60 tyres (base models of this vehicle came with 16" x 6.5" steel rims and 215/70 tyres).
    There seems to be plenty of room in the wheel arches and I'd like to replace my current rims preferably with a bigger size. Bearing in mind I also want to retain functionality for light off-road use could you suggest a practical minimum sidewall height? Would it be a good idea to stick with a sidewall height ~60% of the tyre width? Thanks

  28. So can someone help me, I have a 16×7 +40 wheel, 2007 honda civic sedan and it’s on eibach lowering springs, it only dropped like 1.2 inch overall and I want to know what size tires should i get

  29. Or you can do fitment the mk2 and mk3 vw way by putting other car manufacturers oem wheels on that are way to wide which forces you to use near disasterous tire stretch and ridiculous negative camber and then pray that you poked out wheel dosent slam to hard against the fender lip causing a tire blow out that makes you understeer right off the road in to a ditch

  30. 2017 Honda Accord v6 Touring sedan. 20×9 Niche with +35 offset. 245/35 R 20 Toyo HPII. Any foreseen or unforeseen issues with fitment here? Comments and suggestions please. Thanks.

  31. What measurement determines brake caliper clearance. Will all toyota rims on various models with the same diameter, bore, pcd, offset, etc be interchangle for example.

  32. what about upsizing frm 17 to 18s but not downsizing the tyre and keeping the same sidewall to fill the wheel arches more on stock suspension?

  33. I don't want bags on my car but would like to make it look more aggressive not any of the slanted wheels aka hella camber or stance maby something flush if that exists

  34. I want change. 17 to 18 wheels. But 18 will be heavier. Can damage. My engine or suspension this change or is secure to do it

  35. Havev a 2000 monte carlo and wanna run some gold hundred spokes. Im thinking a 15×10 with a 245/ 50/15. Do you think a 14" rim would still clear the brakes if i wanted to run a 14×10 or 14×8 instead?
