  • I'm Ryan from extremeterrain.com, and today we're gonna talk about how you choose the
  • best tire for your Jeep.
  • We're gonna be doing a lot of videos like this so make sure you subscribe to our YouTube
  • channel to see the latest.
  • Today we're gonna be talking about the pros and cons of different tire sizes.
  • We're gonna take you out on the road and finally hit the trail to really illustrate the differences.
  • Today to show the three different tire sizes that we're talking about, we have three different
  • Jeeps.
  • Starting on my right, we have a four-door Sahara that has a 2.5-inch TeraFlex lift kit
  • with shocks.
  • It is running a 17x9 inch mammoth black type 88 wheel with a 33-inch Nitto Terra Grappler
  • tire.
  • Directly behind me, there's a Dune, four-door JK that has a 3.5-inch Rock Krawler XFactor
  • lift kit that is running Mammoth Boulder Beadlock Style black wheels in the 17x9 and those are
  • wrapped in a Mickey Thompson Baja MTZ that is a 35x1250.
  • Finally, we have a black four-door Rubicon that also has the same 3.5-inch XFactor Rock
  • Krawler lift kit, but it also has an inch and a quarter rough country body lift which
  • is why looks a little bit taller as well as the flat fenders.
  • That Jeep is running the Mammoth DWindow black steel wheels in a 17x9, and those are wrapped
  • in a Nitto Trail Grappler that is a 37x1250 inch tire.
  • There are a few different reasons to wanna put a larger tire on your Jeep.
  • One is for the looks, but another is so that you can roll over obstacles off-road a little
  • bit easier and have a larger footprint off-road, so you have more traction.
  • But when you go up to a larger tire there are certainly going to be pros and cons, and
  • that's what we're gonna talk about today.
  • So, the first tire we have over here is a stock 31-inch tire off of a JK.
  • This is a Bridgestone Dualer AT, and this is a 255/7018.
  • Now, tire sizes are in both metric and in standard, we're gonna be using standard inch
  • measurements.
  • So this is roughly equivalent to about a 31, 32-inch tire that is about 10, 10.5 inches
  • wide on an 18-inch wheel.
  • Now, this is going to be a factory wheel, so it's gonna have a little bit more backspacing
  • than these aftermarket wheels.
  • When you go with a wider tire, you need a little bit less backspacing to clear because
  • you do have that wider tire.
  • But with a narrow 10.5-inch tire like this, you can get away with a little bit more backspacing
  • and tuck the wheel a little bit closer into the Jeep.
  • This is going to be as it says in the name, an all terrain tire.
  • So you're gonna get very little tire noise when you're driving down the road.
  • You're also gonna get really good tire wear.
  • With a big knobby mud terrain tire on the street, you are gonna wear those tires out
  • a little bit quicker than you would an all terrain tire like this.
  • This is also going to have a smaller sidewall because it is a smaller tire and you're running
  • an 18-inch wheel.
  • There's less sidewall, so you have a little bit better handling, a little bit less of
  • that squishy feeling that you can get when you have a larger sidewall.
  • The next tire we're talking about is a 33-inch Nitto Terra Grappler, which is still an all
  • terrain tire and it is going to be a little bit more aggressive than that Bridgestone
  • Dualer that we just talked about.
  • Again, this is roughly equivalent to a 33-inch tall tire that is 12.5 inches wide, and this
  • is going to be on a 17-inch wheel.
  • Now, because this is gonna be a taller tire and a slightly smaller wheel, you are going
  • to have a little bit more sidewall, so if you're taking turns at speed, you might have
  • a little bit more of a squishy feel it may not be as firm.
  • Although let's face it, Jeeps aren't race cars.
  • You're not driving a Jeep for its cornering ability.
  • What you're going to get from a tire and wheel combination like this because you do have
  • a wider 12.5-inch tire on a 9-inch wheel, is some additional sidewall pressure, and
  • the ability to air down the tire a little bit further off-road without the risk of losing
  • that bead.
  • As you air down a nice wide tire like this, you're getting a bigger and bigger footprint
  • giving you even more traction to get over obstacles.
  • The 35-inch tire we're talking about today is a 35x1250 inch Nitto Trail Grappler MT
  • that is a mud touring tire.
  • So, this is going to have the big knobby treads that aren't going to wear quite as well on
  • the road and give you a little bit more road noise, but the pro is that this is going to
  • give you some really good traction off-road.
  • Now, when you go up to a 35-inch tire, you have a couple of things going against you.
  • One is just the height of the tire, and the other is the weight.
  • When you go up to a larger tire like this, it changes your final drive gear ratio which
  • can make your Jeep feel sluggish if you don't regear, and regearing is expensive.
  • So, if you're looking to save on parts and keep your build a little bit on the lower
  • end of the budget, I would recommend sticking with a 33-inch tire.
  • However, you are definitely going to notice a difference.
  • The other thing that you have going against you with a big tire like this is the additional
  • weight.
  • That additional weight no matter what you're gearing is, will make the Jeep feel a little
  • bit more sluggish.
  • The pros to a bigger tire like this is that you are gonna be able to roll over obstacles
  • off-road a little bit easier, and when you air this down, you're gonna have an even larger
  • footprint than you would with the 33.
  • Finally, we have a 37-inch by 1250 Nitto Trail Grappler MT which is the same tire as the
  • 35, but of course, a couple inches bigger.
  • A 37 is pretty much the largest tire you're gonna go with on your JK without starting
  • to get into the realm where you have to cut the body to clear these larger tires.
  • A 37, while it looks mean, you have much less resistance when you're rolling over large
  • obstacles off-road, and you can get a huge footprint when you wear this tire down.
  • You do end up with even more issues if you don't regear your Jeep.
  • This is going to be a really big heavy wheel tire combination, so you're definitely gonna
  • get a sluggish feel when rolling down the road, so regearing is a must with a big tire
  • like this one.
  • Now that we've introduced the four different tires let's take a couple of them out on the
  • road and then out on the trail to really illustrate the pros and cons.
  • So now that we introduced those tires, it's time to actually take a set out on the road
  • and really compare and contrast and talk about the pros and the cons of each one.
  • Now, in general, I think everyone can agree that they want a bigger tire.
  • Bigger is always better, especially when you're talking about tires.
  • However, again, there are some negatives to having a big tire.
  • The Jeep we're driving in today has a set of 33x1250 all terrain tires on it.
  • And by having a smaller tire, that allowed us to get away with a couple of things.
  • This Jeep is still going to have a good amount of pep and pick up because we do have a smaller
  • 33-inch tire on it, all without the need to regear.
  • Now, any time you're putting a larger tire on your Jeep, it's always a good idea, especially
  • if you have an automatic transmission to use a recalibrator.
  • That will let the computer in the Jeep know that you have a larger tire and allow it to
  • adjust for the shift points, but you're still not going to get that full peppy feel back
  • that you would if you had a factory tire on the Jeep.
  • So again, a 33-inch tire's gonna give you something that is larger.
  • It's going to give you a little bit more of that off-road look.
  • It's also going to give you a little bit more performance off-road by giving you the ability
  • to roll over obstacles a little bit easier and also giving you a bigger footprint.
  • But, you don't have the major drawback to a 35-inch tire or a 37-inch tire of needing
  • to regear to get that peppy feeling back.
  • And these are all things that you have to consider.
  • If your Jeep is just going off-road, then yeah, 37 is gonna be the better tire for your
  • off-road situation giving you more clearance and giving you the ability to roll over obstacles
  • easier.
  • And you don't have to worry about the drawbacks to driving a 37 on the road.
  • But, if you do have a mixed purpose rig or if you're building a specifically on-road
  • build, then a 33-inch tire is going to probably be the better choice for you.
  • If you are looking at a larger tire for off-road ability, it's important to remember that a
  • bigger tire is going to give you more clearance to the bottom of your axle.
  • However, a lift is going to give you more clearance to the bottom of your Jeep, to the
  • belly pan, to the frame.
  • And those two clearances are very different.
  • In a minute here, we're gonna hit the trail, and we're gonna be able to illustrate that
  • as well as the difference between how easy it is to roll over an obstacle with a 37-inch
  • tire versus a 33-inch tire.
  • So, here we are on the trail.
  • I'm still in the Jeep with the 33-inch tires on it, but we also have a Jeep right behind
  • me with 37-inch tires on it.
  • So, we can really show you guys the difference between how these tires work off-road when
  • you come up to an obstacle.
  • The first thing we're gonna do is find an obstacle that we can clear easily with the
  • 37s and really show you where you're gonna gain clearance with those tires versus the
  • 33.
  • And then we'll show you how easily a 37-inch tire rolls over an obstacle versus the 33-inch.
  • So, you can really have an idea of where the benefit comes in with having a larger tire
  • off-road.
  • So, with this obstacle that we found on the trail, we're really gonna illustrate the difference
  • between the clearance you get from having a larger tire, versus the clearance you get
  • from having a larger lift.
  • The larger tire will give you more clearance between the ground and the axle, where the
  • bigger lift is gonna give you more clearance to your skid plates and your frame.
  • So, let's roll over this obstacle with the Jeep with 33s and then with 37s to really
  • show you the difference.
  • Here comes the Sahara with the 33s, let's see how it does over the obstacle.
  • So, as you can see with the 33-inch tires, we did hit the log with the pumpkin.
  • This is just a log, it's not gonna cause a lot of damage, and it's gonna move out of
  • the way.
  • But if we were on a trail with rocks or if that was a stump, and we hit it with speed,
  • we may have peeled back the differential cover.
  • We could have caused some damage.
  • Or in the best case scenario, we just got hung up, and we would have had to back up
  • and try going around a different way.
  • Now, we'll see how the obstacle gets cleared with the 37s to really illustrate why having
  • larger tires is beneficial when you're off-road.
  • As you can see, now we have plenty of clearance between the bottom of the pumpkin and the
  • obstacle, even with this larger and differential on the Rubicon than we had on the Sahara.
  • And that's all thanks to the 37-inch tires versus the 33s.
  • So, clearance to the bottom of the axle is one thing, but you also get the ability to
  • roll over obstacles easier when you have a larger tire, so let's find some other obstacles
  • and check that out.
  • Another benefit to having a big tire off-road is that it rolls over obstacles a lot easier
  • than a smaller one.
  • So, the Rubicon on 37s will have much less trouble getting over this log than the Sahara
  • on the 33s.
  • And even though this is just one log in the middle of a fairly open trail, what that translates
  • to when you're off-road, and there's lots of obstacles, stumps or even rocks, is the
  • day when you're dragging the axle over obstacles all day long, or you're cruising along to
  • the next trail.
  • So, today we went over the pros and cons of running a 33, a 35 and a 37-inch tire both
  • on the road and on the trail.
  • Make sure you comment below to let us know what setup you're running on your rig or if
  • you have any questions about what we went over.
  • But for now, I'm Ryan from extremeterrain.com.
  • Thanks for watching.
