Rated 5 out of 5 by from Great tires. Great price. I bought a 2008 Dodge Ram 1500 5.7 Hemi Big Horn edition in 2015 and the truck had these on when I purchased the truck. Not sure how long they were on the truck with the previous owner but they have held up extremely well over the past 4 years, even in the brutal Arizona heat. I have about put about 40,000 miles on them since buying the truck. I rotate them regularly and they have worn evenly, been extremely sturdy yet provide a smooth drive. I'm putting new ones on today and am extremely pleased with the price point and quality these offer. I've paid nearly triple the amount on other brands and these either rivaled or exceeded the quality of those other brands. I will continue to buy these for my truck(s) as long as they keep making them.

Rated 1 out of 5 by from Not an all-season tire Spent the time to really review tires for my 2015 Ram 1500 before buying these. Was looking for a well rounded all-seatson tire and this scored high in rating and reviews. I live in New Brunswick, Canada and we have heavy snow in the winters and hot summers. Almost all of my driving in city and highway driving. Got less than 20,000km out of my first set before their failed inspection because they were so worn, despite regular rotations. Warrantied them through Canadian Tire and I haven’t even gotten 30,000km out of the second set and they are completely bald. Will never buy them again. I do not recommend for maritime weather in Canada.

Rated 2 out of 5 by from Disappointed!! Bought a set of these 1 year ago, roughly 10,000 miles.Load Range E. Driving down the highway ran over a lead wheel weight(did not see it).The weight pierced the tire and because of the size of the puncture the tire was left unrepairable.I sure expected a lot more from a 10 ply tire

Rated 5 out of 5 by from Best winter tire I have ever had. I have had many different tires and dedicated winter tires. This one even outperformed the Cooper ATP I bought and paid extra to have siped. At the time I thought it was the best. The ATW far surpasses it. Combined with 4WD, it has been thus far, unstoppable in even a foot of snow. Has great stopping bite even on hardpacked compacted untreated snow. Or what we refer to as pack ice. I work for the County Highway department and absolutely must get in when called to clear roads no matter how bad the storm conditions are, 24/7. This tire is a pleasure to run in the worst conditions on my Tahoe.

Rated 5 out of 5 by from EXCELLENT TIRE Just purchased 6 of these for my 1998 Dodge Ram 3500 4x4. For the last 2 winters, the tires I purchased were just weak - had very minor (thankfully) slides on ice that have never happened before on my 320,000+ truck. I've known this truck since brand new, so I know what my truck likes. I spend my weekends in deep winter weather. This past weekend was 1st real test - passed with flying colors! Found myself going faster and more secure than I have in quite awhile! Highly recommend. They passed the Valley County Idaho winter test!

Rated 2 out of 5 by from not the tire for me I bought these tires as a replacement for the factory firestones. I purchased in late March early April 2017 with about 6k on the truck. I now have 25k on the truck and its November of 2018 and tires are worn evenly but all 4 are down to a few 32nd of an inch. As far as traction they were great but to only 19k miles out of the tires is unacceptable. especially what I paid for them. and yes they were rotated on a regular basis and a 4 wheel alignment performed to make sure it wasn't the truck causing the wear. Bottom line is the st max is a better tire

Rated 4 out of 5 by from Comparing to Bridgestone Ravo2 I have a 2006 6l diesel F350 crew cab,long bed 4x4 w/18 inch wheel, and 2000pnds RV Camper on top. live in central coast, California, USA. I purchased this tire, because I know I was going to go to Northern Territories in Canada in February (plenty of snow storms and very cold), and I was aware I was going to drive also in B. C.,Canada (they still require either winter tires or chains,I had both) I have to say the tires are a little noisy on a road asphalt or cement, bet perform well at any speed being dry or wet. I was surprised on how well it performed on ice and snow when dry. when you hit wet black ice , watch out (to be fair, this happens to any tires!!! On Mud and dirty road performed well. After driving over little more than 10,000 on this tires, wear is not yet noticeable.I wish this tires where a little less noisy (hi preached hum) For the price and behavior, overall very good tires.If I can make over 40,000 on this tires, It will make me very happy!

Rated 5 out of 5 by from Great all around tire . I've yet to find a problem with these tires . I bought them as a winter tire as we are required to have the mountain snowflake on our tires here in the winter . I ended up leaving them on all summer as they seem to drive quite quietly with great mileage on pavement . I live in the mountains where it snows a lot and drive a logging road to get to work . These tires track well on gravel and mud as well. 40K on them , rotated every 10k and lots of tread left . Ram 1500
