Mickey Thompson ATZ Tire Test

Posted in How To: Wheels Tires on May 1, 2011

As automotive adventure journalists we drive the heck out of vehicles. In four months' time we can often drive more miles than a long haul trucker. Putting mileage like this under our rigs gives us more than enough time to evaluate a set of tires in a number of conditions. It also gives us the time to put the tires through the mother of all toughness and dependability tests.

The Baja ATZ radials grip very well on the rocks. We have run the tires over a number of rugged trails over the past few months and haven't noticed any cuts, chipping, or gouges of missing rubber. The ATZ tire uses a specially designed compound that definitely helps them hold up in harsh conditions on and off the road. The dependable radial has more rubber on the tread than any all-terrain tire we have tested, which accounts for its long life.

In the Jan. '11 issue ("Suspension Checkup") we explained to you that properly maintaining your suspension will help extend the life of your tires. At that time we mounted a set of 35X12.50R/17 Mickey Thompson Baja Radial ATZs on our Ram truck and stuck to our tire maintenance program!

With some minor maintenance such as keeping proper air pressure in them and rotating the tires, the Baja ATZs held up exceptionally well over the past five months, with minimal wear. Given what we have done to the tires there's no unusual road noise from unevenly worn tread lugs, and we haven't experienced any flats, sidewall tears, punctures, or mysterious depressurization. In fact, the tires still look almost like they did the day we slapped them on the truck.

With a few thousand miles on them, our Baja ATZs show very little wear. The tread features wide voids between the lugs, which are also heavily siped, and we have experienced good traction on wet and icy roads. The self-cleaning tread has also proven its worth in light mud. The tire is constructed with six-ply tread (one nylon, two steel, three polyester) and three-ply polyester sidewall belts.
