First Ride On The New 42 Inch Goodyear MT/R TiresPosted in How To on September 1, 2009 0) (
We feel pretty lucky right now since we are some of just a few people who were able to get our hands on a set of the new 42-inch Goodyear MTRs. The new MT/R Goodyear with Kevlar has really hit a homerun with these true 42s that measure every inch of their labeled diameter and stick to rocks like chewing gum.
The original MT/R spent quite a few years as a popular tire with an unchanged tread design, but this new version has all the impressive traits of the last MT/R and more.
The tread has been separated into four ribs that follow the circumference of the tire and seem to give it a directional tread pattern, even though it is not directional. The tire, when fully inflated, puts the majority of weight on the two centered ribs. One of these ribs has much less tread void than the other ribs to give a smoother rolling surface for on-road and high-speed off-road travels.
We tested the 42-inch MT/Rs on a new four-door Jeep JK Wrangler, but it has been outfitted with so many aftermarket upgrades that this vehicle weighs more than some fullsize trucks. Did we like the results? Oh yeah.
To say that we enjoyed testing with this tire would be an understatement. Not only did the Goodyear 42-inch MT/Rs surpass our expectations in the dirt, but also on rocks too. The tire did an amazing job of sticking to obstacles and pulling itself up onto things that other tires would just sit and spin on.
The sidewalls proved to be very flexible, even with the added Kevlar, and throughout all the testing, we never put serious damage into any of them.
The highway ride was not the best we've ever had, but the tire is still more than suitable for driving on every day and we were more than happy to sacrifice a little on-road performance for the awesome off-road performance.
