Update: Cooper Discoverer A/TW, Great in Winter and Proving Itself Capable in Spring and Summer TooPosted in How To: Wheels Tires on August 13, 2018
We recently reported on our winter test of the Cooper Discoverer A/TW all-terrain tire. It earned the proverbial two thumbs up in that venue, and if we had more thumbs, they would have been up too. But there is more to a year than winter, so here’s a follow-up report that covers what it’s like to live with the A/TW in the spring and summer in a work environment.
The A/TWs are mounted to an old ’86 F-250HD diesel 4x4 that has been busy. In the spring, it hauled 3,000 pounds of soybean seed. It’s schlepped some firewood, hauled a farmer around some plowed and unplowed fields, made dump and scrap runs and…the usual stuff. Harvest is a couple of months away at the time of this writing, and it will be hauling loaded grain wagons to the elevator.
After wearing somewhat noisy 33-inch all-terrains for a good part of its 31-year life, the whisper-quiet A/TWs have been welcome. If only we could say the same thing about the old 6.9L diesel. Dry traction on the highway is superb. We notice it most in unloaded hard braking, where the nose-heavy, non-ABS, rear-drum-brake truck is prone to locking up the rear tires. That tendency is very much reduced. The compound and tread design make wet weather road traction great too, where the locking-up scenario is more pronounced.
The tires have been taken in fields, on wood lot runs, and in some light mud, all of which were handled with aplomb.
Bottom line, we think highly of the Cooper Discoverer A/TW in the all-season work truck environment. We look forward to a long and happy relationship with these tires.
