Reviews

Rated 1 out of 5 by from Wear Out Quickly 1 Star is still too generous. The tread life of these tires is an absolute joke. I am running P275/60R20 on my F150. The tires were put on the truck when I purchased it. The truck had 200kms on it when the tires were installed, it now has 27,276 on it and the tires are between 4-5/32nds remaining. I rotate my tires every 8,000 kilometers when I do my oil changes. The tires are wearing evenly however there is no chance that these will last even close the amount of kilometers stated in the tread life warranty. I WILL NOT purchase Cooper tires again and WOULDN'T recommend them to anyone. The truck is driven 95% of the time on paved roadways so it is not from abusing them out in the bush. Spend your money elsewhere, I know I am.

Rated 5 out of 5 by from Love copper tires My last three sets have been copper tires. I’m a huge fan. They perform great in all weather conditions even up here in Canada. I have discoverer srx on my wife’s suv And discoverer h/t4 on my ford 250 great tires! I snow plow and haul trailers all day no issues at all !

Rated 5 out of 5 by from The best in all season tires Best tires I've bought in years. I drive 90% highway and 10% dirt roads all year round. Great traction in rain,snow, ice and mud. I will definitely buy theses tires again

Rated 4 out of 5 by from Excellent traction, wear, quietness for all weather tire. Have 30,000 km on Colorado diesel 4x4. Have about 25% towing. Wear has been excellent with no cupping, or other unusual wear characteristics. Extremenly quiet and great handling. Siping and tread blocks exhibit no tearing, chipping or chunking. Traction on dry and wet pavement is easily 80% of summer tire and gravel, ice and snow traction is also excellent. Also at least 80% of winter tire. Mud traction is absolutely acceptable for a year round tire. I WOULD like some more sidewall protection or small sidebiters to protect sidewall during reduced pressure off road situations. I will ABSOLUTELY replace with another set.

Rated 5 out of 5 by from Can’t beat this tire for the money I put these tires on my 2000 Silverado and I was very impressed with their performance. 2 wheel drive with locking differential was amazing on the highway with snow. Low road noise and all at a reasonable price. I have had premium tires on this truck which performed the same but it cost significantly more money. I will be putting them on my 2017 Silverado when it’s time to replace the factory set.

Rated 5 out of 5 by from All weather, Very capable snow/ice tire. This is a Excellent “All Weather” tire, a 8 out of 10 vs a full winter tire on ice, no changing! A 9 out of 10 in a foot of fluffy snow, or packed road snow, have not had in mud yet.
