Huge Upgrade Over Kenda R/T – Quieter and More Stable
I replaced my Kenda Klever R/T tires with the Cooper Discoverer Road+Trail AT 265/65R18 XL 116H on my 2019 Nissan Frontier 4x4, and the difference is very noticeable. The Coopers are much quieter on the roadway and rides smoother overall. Steering feels more stable and controlled, especially at freeway speeds. The Kenda R/Ts were more aggressive looking and probably better for serious mud, but for daily driving, highway travel, and light off-road use, the Coopers are a huge upgrade. I can actually hear my stereo again! Very happy with the switch. Would buy again.

Great Traction, quiet on roadway, semi aggressive look
Super happy with these tires, i've been everywhere with these things from snowy roads, rain, (some mud) And they've never failed. Great traction, great braking capabilities and I can take corners with more confidence. Overall pleased with purchase and will probably continue buying these tires for my truck in the future. Plus they look nice.

Awesome tires
Terrific tires. They are quiet for being all terrain and the price on Amazon was unbeatable. Cooper Tires are awesome. Had these installed on my 2016 Tundra.

Very good grip on the snow
Installed on my 11 Kia Sportage and it helps the AWD system a lot, you can feel an improvement on the grip, and the best part is that isn’t noisy on dry asphalt

AT3 replacement
Replacement for AT3 tires, tread isn't quite as aggressive but seem okay in the snow off-road Definitely quieter than the AT3 tires

Good tires for ice and snow. A little more expensive than local tire shops. But fast delivery
