Update: Cooper Discoverer A/TW, Great in Winter and Proving Itself Capable in Spring and Summer Too

Posted 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.

The closest thing to wheeling in the test period was a trip to the local fishing and boat launching area. No drama this time, but sometimes the climb can get pretty greasy. We think the A/TWs would be able to handle it.

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.

A freshly plowed field can be a challenge in the flotation area, depending on the type of soil. In this case, the awesome Big Bud 650/50 in the background was plowing about 10 inches deep with the legendary 21-bottom DSI plow, the biggest moldboard plow ever made, but the A/TWs kept our truck moving.

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.

Loading up for a dump run! Isn’t that exciting? Still, it’s one job a farm truck must do, rain or shine and in any weather.
