In this business, tire testing has got to be one of my favorite tasks. Engine performance mods and suspension systems analysis is ok but wheels and tires are the most notable thing about four wheel drive trucks trucks. And for the 12 years that I have been writing tech articles and for all the tires I have tested, I have to say that I now have a new favorite tire.

In 1997 Scott Ward founded the Pro Competition Tire Company. A company dedicated to the Light Truck/Sport Utility Market with an emphasis on Four Wheel Drive. These tires are built in the United States and made with Dual Guard™ side wall construction for extra side wall protection. Pro Comp Tires have a dual compound rubber design for tougher resisting against scrapes and cuts. The Dual Compound Tread composition allows the tires to wear longer due to cooler running, prolonging the life of the tire. Pro Comp’s new advanced tire technology enables top performance in snow without the use of tire chains and carries the new “severe weather” approval rating required by many states

With that, we have been allowed to test a set of the All Terrain tires which come with an industry standard setting 50,000 mile warranty and a “no questions” road hazard warranty. For a tire company so new in the industry that’s quite an accomplishment.

After receiving the tires and a set of 15X10” Xtreme Alloy® wheels (also built by Pro Comp) we mounted them up and went to work. The first thing we noticed was that the safety bead was very strong, most tires have a notable “pop” when they seat onto the rim. These let out a nice loud “pop” when they seated telling us that they would hold to the wheel under most any circumstance.

After mounting the tires I drove the truck to my local tire shop to have them balanced. While driving to the tire shop the tires ran smooth and straight. There was no noise coming from them and no shimmy from the steering wheel, these tires were pretty well balanced that I decided to forgo the balance until the end of this test, so at this time I still haven’t had them balanced. That’s amazing for a 35” tire of any kind. I will have them balanced soon to make sure they give maximum performance and endurance.

We headed for the Little Rock Dam Off Road Recreational Vehicle park for a little wheeling and rock climbing to see how they worked. I towed a Jeep sporting a brand new set of Xterrains that were to be tested at the same place. With the tire pressure at 24psi there was no notable swagger in the rear due to the extra weight of the trailer and Jeep indicating the sidewalls are pretty stout for a load range C tire. Once we hit the off road area we left the pressure at the street pressure to see how well they would do in sand and on rocks. The tires preformed admirably and we were only disallowed up a hill once for lack of momentum. Having the tires aired down to 15 psi we finally started to notice the bulge as we climbed some boulders. That hill we missed was no longer a problem and the sand performance also improved notably.

The snow always offered a different set of challenges. The Pro Comps worked very well in the snow and even in the mud that we encountered on our way to the snow. There was no slid slipping even with lockers front and rear, and the tread cleaned itself easily in the shallow snow at street pressure. We aired down to 15 psi again to see how the deeper snow would challenge us and we found no problems there either. With the siping in the tread blocks the wet streets offered no problems for the Pro Comps.

The tires performed admirably over the rocks and in the sand. We first hit the sand while still at street pressure and never felt that we would get stuck. Then we aired them down to 15 psi to see how they would perform on the rocks and for an all terrain design they do work well. Riding out of the creek and straight up a rock was no problem for these tires with only a minimum of slip from being wet I was still able to complete the climb.

All in all I would have to say that the Pro Competition Tire has created a great working All Terrain tire that will go the distance and work hard the entire time you run them on your truck

At 5000 miles these tires have still not been balanced. I took the truck over to the Affordable Tire store in Palmdale last week to have them rotated and they checked the balance...still right on the money. That sayw a lot for a tire that big and a wheel that wide. I mounted them myself on my friends machine so there was no "fixing" the test by Pro Comp. I you are looking for an exceptional all terrain tire...I'd have to say that these tires are as good as BFG's or any other manufacturer.

I have had a set of ProComp All Terrains on my 98 Dodge Ram 2500 4x4 for over four years now.  In that time, I have driven across the US twice, and put about 40,000 miles on them.  I have played in the mud with them, and towed a lot of weight.  I had never had an issue with these tires, and it's time to replace them now. 

The treadwear has been great, but now the traction is beginning to be an issue.  We had our first snow/ice storm of the year here in Western Washington, and the tires were less than impressive.  It's not that they were really bad, per se, but they were not nearly as good as I remembered.  The tires don't have the bite that they used to, but I don't suppose I should expect them to after 40,000 miles.  They have 3/32" of tread left, and are definitely worn down.

I have considered purchasing a new set of ProComps, however their lack of a 285/75/16 in load range E will keep me from doing so.  If this truck was not used for towing, I probably would purchase another set of ProComp tires...
