Cooper Discoverer STT Pro 255/75 R17 Jeep wrangler jk 7 miles November 29, 2022
Northern Ontario, Canada. Two lane highways, bush roads, lots of trails, and made a couple new trails. 2014 Jeep Wrangker 2 door. All stock. Just ran these for a season April - November. Mix of road and trail. They did very well in mixed off road, sharp rock, gravel, mud, rust, smooth rock, wet/dry, bush roads. No issues. Clawed their way through everything. No cuts, no punctures, no issues. On road, not bad either. I didn’t experience an hydroplaning on highway (55mph/90kmh). Wearing very well, light feathering. 12,000 kilometres / 7,500 miles. Rotated once at 7,500 Km’s. 5 tires rotation. Swapping out to winter tires now. Wouldn’t use them for winter. Snow maybe, but not cold temps or ice. Less noise on pavement than I expected, that is subjective, but I expected worse from these. All in all, I would buy these again and recommend them.
