Jeep Wrangler Cooper Discoverer S/T Maxx Tire (31-35″) (1987-2018 YJ, TJ, JK & JL) Review


The Cooper Discoverer S/T Maxx Tire is for
those of you who that have a 1987 all the way up through the most current model year
Wrangler, that are looking for a mud-terrain tire that’s just a little bit less aggressive
than some of the other options out there. This tire’s gonna be available from a 15 inch
wheel to a 20 inch wheel, and in sizes from 31 to 35 inches tall. Now, when you talk about tires, you have a
mud-terrain tire. Your more traditional mud-terrain tire has
these huge lugs with big spaces in between them that give you a ton of traction, and
also the ability to clean out the tire when it gets caked up with mud when you’re off-road,
giving you that bite back to the tire. Now, this is still gonna do that for you. This has some big lugs, with some big clean
out areas in between it, but this is a little bit more of a hybrid tread. So the center section of the tire, here, is
actually a little bit more all-terrain looking in my opinion. And the benefit to that is the fact that this
is gonna be a little bit quieter, and it’s gonna wear a little bit better on the road
than some of those more traditional-looking tread patterns on your more traditional mud-terrain
tires. So, this is gonna be a great tire. This is gonna give you the ability to have
these big lugs that are gonna be self-cleaning off-road, giving you a ton of traction, a
ton of grip. It’s also going to have this sidewall that
has a little bit of tread on it as well, giving you the ability to grip with the sidewall,
also giving you the ability to have a nice cut-resistant sidewall. The rest of the sidewall that doesn’t have
the tread on it is going to be a three-ply sidewall, so giving you a ton of strength
there. So, in all those ways, this is going to be
a very good tire off-road. But because it does have that hybrid tread,
when you’re on-road it’s gonna to wear a little bit better and it’s gonna to be a little bit
quieter, which are going to be some pretty nice features. So, as far as construction goes, pretty much
what I already mentioned here. You’re gonna have a three-ply sidewall. A little bit of tread on the sidewall for
grip, and for strength, and for puncture resistance. You’re also gonna be able to air this tire
down a good bit, and get some really nice traction. Now, speaking of airing down, the big lugs
that you do have on the tread here, they are siped, and what that means is they basically
have a cut in them. So, that allows that lug to flex and really
grip when you do have this aired down off-road. So you’re gonna have those big lugs with the
big self-cleaning spaces. Like a lot of the other tires out there, this
is designed not to chip, not to chunk, which is a problem you can have with some of the
cheaper sort of no-name-brand tires. When you have a mud-terrain like this, some
of these points, some of these ares of these big lugs kind of wanna break off on you when
you’re off-road. This tire, and a lot of the other tires that
we carry, those well-known, well-built tires, they’re not gonna have that problem, this
one included. As far as getting this installed, you are
gonna want to take the tire and your wheels to a mount and balance shop. If you do get a big 35 inch tire, sometimes
the shop won’t want to balance that tire out until you put about 500 to 1,000 miles on
it. A lot of rubber does come off the tire in
those first 500 to 1,000 miles, and the balance is gonna change. So, sometimes they’ll just have you drive
around for a while, come back, then get them balanced. If your shop does wanna do that, don’t worry. It’s a completely normal thing when you’re
talking about a big mud-terrain tire like this one. Now, we’ve all seen the YouTube videos of
people mounting up tires in their driveway, using some sort of combustible. I definitely do not recommend that. That’s a trail fix, at best. You’re definitely gonna want to go a mount
and balance shop and have them put these on your wheels for you. The pricing on this tire’s gonna fall anywhere
between $200 a tire and $300 a tire, and that is, of course, going to depend on the overall
size of the tire. The bigger the tire, the more rubber is there,
the more expensive it’s going to be. But, also, the wheel that you’re going to
mount the tire on affects the price. If you’re mounting it on a big 20 inch wheel,
that tire’s going to be more expensive than a tire designed for a 15 inch wheel. It’s just the way it goes, you would think
it’d be the opposite. So, do keep that in mind. If you’re going with a bigger wheel and a
bigger tire, it’s going to be more expensive than a smaller tire designed to be mounted
on a smaller wheel. Overall, I think that for a mud-terrain tire
that has a three-ply sidewall, I think that this is going to fall right in the range of
where you would expect it to be. There are some less expensive tires out there,
but some of those only have a two-ply sidewall, which is going to be a little bit of a detriment
when you’re off-road. You’re gonna be able to puncture that sidewall
a little bit easier. So, again, for what you’re getting here, I
think it’s very fairly priced and I think it’s going to be a good deal. So, if you’re looking for a slightly less-aggressive
mud-terrain tire that’s gonna wear well and be a little bit quieter on the street for
you, I would recommend taking a look at this Cooper S/T Maxx that you can find right here

  2. I'd like to replace/upgrade my stock Bridgestone Duelers for a more aggressive all-terrain tire but keep as much on-road manners as possible. I'd go with this one or the "Nitto Terra Grappler G2" . . . what is your take on that idea? I like your website's ability to show how the different tires/wheels look on my JK. 🙂 Thanks for all your videos and thumbs up, Joe

  3. I stand by these tires! Have them 285/75r16 on my 2017 tacoma and they handle it all, I aired down to 20 psi for flagpole knob and for rausch creek and it does it all no problem and no worry about puncture! Amazing in snow as well, was breaking trail here in NJ 8 inches of snow no problem

  4. I have the 35's on my TJ. They do great on the rocks, I usually air down to 8psi and they have never let me down.

  5. Thanks for the video, not too many around the web.. But please don't call this a mud terrain when you know it's an aggressive all terrain/hybrid as you said. Very confusing for people trying to learn. I love cooper tires, I'm getting these in 34s next.
