WE TEST THE DEEGAN 38 ALL-TERRAIN
BRIAN DEEGAN IS MANY things. X Games gold medalist, metal Mulisha founder, freestyle motocross pioneer, short-course racing champion. These credentials motivated Mickey Thompson to sponsor Deegan and even create a Deegan line of tires and wheels.
Mickey Thompson started with the Deegan 38 Mud-Terrain tire, which is just as tough and aggressive as Deegan himself. The guy has another side, though, one that is rarely seen. Loyal husband, dedicated father, successful businessman. That person is best represented by Mickey Thompson’s latest offering, the Deegan 38 All-Terrain.
Hear us out. While not as aggressive as its Mud-Terrain sibling, the new Deegan 38 All-Terrain shares the same DNA that makes the Deegan 38 Mud-Terrain so tough, but with increased tread life and decreased noise for vehicles that spend more time on the pavement than in the dirt. That is the case with our 2014 Ram
3500, which is used to tow our rockcrawlers all over the country. The Ram is not a dedicated wheeler, but it does see plenty of dirt roads and snowy mountain passes on our adventures. These are the situations that the Mickey Thompson Deegan
38 All-Terrain were made for.
The “38” doesn’t refer to the tire diameter, but rather Brian Deegan’s race number. Mickey Thompson currently offers the Deegan 38 All-Terrain in over 30 sizes from
29 to 35 inches and for rim diameters from
15 to 22 inches. LT sizes are backed by a
55,000-mile warranty, and P Metric sizes come with a remarkable 60,000-mile tread wear warranty. We chose the LT295/70R18 size, which comes in a Load Range E that is perfectly suited to towing and is an inch taller than the factory size for our Ram to fill out the wheelwells nicely without regearing.
After more than 5,000 miles, half of which have been with a trailer in tow, the Deegan 38 All-Terrains show little to no
sign of wear. The tires have done everything we have asked of them and never left us wishing for a more aggressive tire on our tow rig. The Mickey Thompson Deegan 38 All-Terrains may not have us doing DoubleNac IndianAir backflips, but they have run smooth, reliable, and whisper-quiet. This is a side of Brian Deegan that we could definitely get used to.
“An All-Terrain makes sense for vehicles” many
1 1 The Deegan 38 All-Terrain has proven to be a very versatile tire on our Ram 3500. This truck is used for everything from daily driving to ski trips in the mountains to towing a heavy trailer. The void area on the Deegan 38 AllTerrain is comparable...
5 5 The tread compound on the Deegan 38 AllTerrain is silica-reinforced for excellent cut and chip resistance. That doesn’t mean that they will last 50,000 miles if you’re peeling out all of the time, but it’s valuable if you spend time on slick boat...
2 The theme with the Deegan 38 All-Terrain is a more subdued version of the Deegan 38 MudTerrain, so it is no surprise that the tires have a toned-down version of Mickey Thompson’s legendary Sidebiters.
3 The Deegan 38 All-Terrains carry an E load rating in the size we tested. Each tire is rated to carry up to 4,080 pounds at a maximum inflation of 80 psi.
4 4 Generous siping allows each individual tread block to run cooler on the road and conform to the terrain off-road. The siping also evacuates water to make the Deegan 38 All-Terrain stable and confident on wet and icy roads.
6 6 The Deegan 38 All-Terrain tires took incredibly little weight to balance (11⁄4 ounces on average), a testament to the excellent quality control exhibited by Mickey Thompson’s line of tires.
