The Goodyear Wrangler MT/R tire is for those of you that have a 1987 all the way up through the most current model year Wrangler that are looking for a very high quality mud-terrain tire. This is available from sizes of 30 to 35-inch tires, so you do have a good variety of different sizes.Now, a mud-terrain tire, in general, is going to be for those of you that are going off-road. A mud-terrain tire's gonna be a little bit noisier and not wear as well on the road, but it does have some great benefits off-road. So if your vehicle is spending most of the time off-road, this is gonna be a good choice. If it's spending most of the time on-road, I'd probably point you toward an all-terrain tire. But what makes this so good off-road? A mud-terrain tire's going to have very large lugs that are spaced very far apart, and the idea there is that when they do get mud and dirt in there, you can get up a little bit of wheel speed and these will clean themselves out. The mud'll fly out, giving the bite back to the tire. If you don't have that, and they just stay caked up with mud, the tire essentially becomes a slick off-road, and you have zero traction. So that is a key to a mud-terrain tire. Generally, a mud-terrain tire will also have some siping in these large lugs, just like this one does, and what that is is a small slice in the lug to allow that lug to flex, so when you're off-road, this tire's aired down a little bit, you're going over uneven terrain, the tire can conform to that terrain, giving you the maximum contact patch and therefore maximum traction when you are off-road.As you'll see here, the tread does continue down onto the sidewall a little bit. Again, that's sort of one of those things that you see with a lot of different mud-terrain tires. That traction is going to be very useful when you're crawling in the rocks, or just generally off-road, attacking some obstacles. And the other big thing that you'll find on a lot of all-terrain tires is a nice strong sidewall. This is going to have a three-ply sidewall, but Goodyear takes it a step further and Kevlar-reinforces their sidewall, so this is a very, very strong sidewall. So again, if you're doing a lot of crawling on the sharp rocks, other off-road debris, branches and those types of things aren't going to be able to puncture this sidewall nearly as easily as it would some of the other three-ply sidewalls, or certainly a two-ply sidewall. So you're gonna get a lot of strength out of this tire, as well as a lot of good off-road traction.Now, Goodyear is a very well-known name brand, and the fact that this has the Kevlar reinforcement in it means it's gonna be a little bit more expensive than the other tires out there, but if you're going to be taking advantage of all of the benefits of a mud-terrain tire, and specifically this reinforced mud-terrain tire, I do think it's gonna be worth the premium.So we already talked a lot about the construction of this tire, and mud-terrain tires in general. Large lugs spaced far apart with the siping, some tread down on to the sidewall, three-ply, Kevlar-reinforced sidewall. This is going to be a very well-built, very strong and long-lasting tire that's also going to do very, very well off-road.Let's talk about getting these installed. You're gonna wanna take your wheels and your new tires to a mount and balance shop. Have them mounted up, have them balanced. Now, some shops won't choose to balance a big mud-terrain tire right off the bat, because so much rubber flings off these things in the first 500 miles or so. So if your shop says, "We're just gonna mount them for you, come back in 500 miles, we'll balance it then," don't be alarmed. That's perfectly normal. Now, we have all seen people that will mount these things in their driveway using some sort of lighter fluid or brake fluid, some sort of propellant to set the bead. Don't do that. Save that for the emergencies, save that for the trail fixes. You're gonna need to have these things balanced out anyway, so just go to a tire shop. Have them set up the right way.Now, because of the big brand name on these tires, and the fact that these have the Kevlar-reinforced sidewall, these are gonna be a little bit pricier than some of the other tires out there. These are going to be anywhere between $200 and $400 per tire, depending on the size. Now, of course, the larger the tire, the more expensive. There's more rubber there, you would expect it, but also the larger the wheel the tire's designed for, the more expensive. So a 35-inch tire for a 20-inch wheel is gonna be pricier than a 35-inch tire for a 15-inch wheel. That's sort of just a general rule of thumb when looking at tire prices.So if you're looking for a mud-terrain tire that has even more sidewall reinforcement than you'll find on a lot of other options, this is gonna be a great choice from Goodyear, and you can find it right here at extremeterrain.com.

What is the best gear ratio to run for larger tires? When you increase the diameter of your tires, your vehicle's engine has to work harder to turn them. Naturally, this will lead to increased fuel consumption and reduced performance. So, when upgrading to a set of larger tires you should re-gear your rig to regain this lost acceleration, performance and fuel economy.
Find your original tire size and gear ratio using the chart listed below, the intersection should be your approximate RPMs at 65 MPH. Then find your new tire size and follow it across to the closest RPM to your original tires, this will be your gear ratio choice.
This chart is based on driving at 65 MPH with a 1:1 gear ratio and a manual transmission in 4th gear. Please note if your vehicle is equipped with an automatic transmission your RPMs will be higher due to normal transmission and the torque converter slippage. In overdrive your RPMs will be approximately 15% to 30% less than indicated.
