Testing the Mickey Thompson MTZ P3

Simply put, we wouldn’t be where we are today in the off-road world without men like Mickey Thompson blazing a trail for off-road enthusiasts like us to follow. So when Mickey Thompson Performance Tires & Wheels comes out with a new wheel and tire combo, it is in all our best interests to take notice.

The new Mickey Thompson Baja MTZ P3 is an aggressive mud-terrain tire and features a unique tread design that continues onto the sidewall for both a menacing look and impressive off-road performance. With the company’s new Deegan 38 Pro 2 wheels, the combination not only looks at home on any rig but also has the performance and off-road heritage to back it up.

Our test rig for these tires is a lifted, daily driven V-10 4WD Dodge truck. It’s an all-around workhorse used for anything from towing trail rigs across the western U.S. to mild trail running to simple hardware store runs. A truck like this needs a tire that will not only work well off-road but also go down the road well and be able to handle heavy loads. The 37x13.5R17LT tires we used for this test are a Load Range D, which is a great all-around compromise for a truck like this. These tires are available in C, D, and E ratings and sizes to suit a variety of vehicles. Mounted on the Deegan Pro 2 wheels, the combo only weighed 108 pounds per corner.

Even with the torquey V-10 truck and 40 psi in the tires, it proved difficult to break these tires loose lugging around on loose, steep, rutted fire roads. Grip is exceptional in dry conditions. The tires tracked well on loose gravel at high speed, and of course what little mud we could find in drought-stricken California didn’t even come close to testing the limits of these tires in the sticky stuff.

The look, performance, and (let’s not forget) legendary heritage that come with the Mickey Thompson name has made us a huge fan of this wheel and tire combo. Finding a comparable package from a single manufacturer is impossible. The tires dug and clawed as we expected them to on what little rock we felt comfortable driving our tow rig on. The three sidewall plies give us confidence that these tires will hold up on the trail.

Running down the highway, we found the hum of the tires to be a minimal sacrifice for such an aggressive tire. The truck remained pleasant and quiet inside despite the large siped lugs, which feature variable draft angles for better traction and improved tread clearing in mud and sand.

We always find it very reassuring when new tires of this size require very little weight to be balanced and spin true. The tires only took 9 1/2 ounces (for the heaviest tire) to balance. The truck drives down the road smoother than it did with the old bald 35-inch all-terrains that preceded these meats. The tires are big, measuring out to 36 inches tall once mounted on rims.
