Review: Fast delivery, fair price! - Product arrived quickly and was exactly what we wanted
Review: Best tires I have owned! - I live up in Saskatchewan. I do a bit of open country snaring for problem coyotes and we typically have a lot of snow. I had nothing but trouble with a set of ALL SEASON tires. Probably dug myself out 40-50 times. I picked up some of these on the recommendation of a local tire dealer. I was presently surprised how quiet they are considering the aggressiveness of the tread. Well like a little by in a candy store I decided to give them a whirl. The snow was 14-16" with a hard pack crust on top of about 4". Weather was +5 celcius so there was some shush and melting. A perfect test scenario. I put my RAM in 4 wheel low and did about a 600 yard loop in the field. I travelled small rolling hills and I stayed out of the bottoms where I could see the snow was much deeper, about 2 to 4 feet. Well I did the loop and I could hardly see anything outside the truck for flying snow and ice chunks. I decided to stop and slow down and NOT use momentum when I got back close to the entrance of the field. I checked the tires and there was NO snow buildup it was 100% self cleaned. I slowly trudged through the rest of the field with no problem at all. My buddy asked if I had a shovel along in case and I did but didn't even com close to needing to use it. I only have 1000km on them but they are awesome.

### ⭐⭐⭐⭐⭐ Cooper ST MAXX
*by R***K on August 11, 2014*

You can't run these lower than 45psi for load D and 60psithey for load E. Having read this on other sites, I was not worried. I have a F350 and haul heavy loads so I run load E with 75the psi. These tires have performed to the 'MAXX'. Across fields fully loaded, highways or back road, mud and snow. I hated paying the price but after 3500 miles of solid abuse there are no chunks, odd wear, or sidewall issues. THESE ARE GREAT TIRES!!!!!!
