WHAT OWNERS SAY
❝
I could not ask for anything more from a tire. They’ve clawed over sharp rocks, rolled smoothly over dry highways, and only sprung one leak — when a nail found its way into the center of one tire. They’re quiet, secure, durable, and long-lasting.
❝
I have zero complaints with them on stopping, pushing a tight canyon corner, or handling wet conditions, and they also have very minimal road noise.
❝
I drive a Kia Sorento with part time 4wd and I do 50/50 road and off road. Dry and mud. I can only say off road these tyres haven’t let me down. I’ve driven across Wales in dry and wet conditions and I’ve been very happy with this purchase.
❝
Ive had these on my 2005 pathfinder 3 years and about 37K miles. They look good, have good traction, and handle well both on and off road. The only negative is that they are really starting to wear even though I rebalance and rotate them every 5000-6000 miles.
❝
The Cooper Discoverer A/T3 tires are whisper quiet on the street. While we spend as much time in the dirt as possible, this is a truck that primarily sees street use for daily driving and towing.
