Reviews

Rated 5 out of 5 by from Great tire for duramax Dually My truck 3500 2013 Chevrolet duramax crewcab dually 4x4-235 80/17 10 ply E range. I bought these because my Toyo AT were wore out after 37k miles. Other store here wanted $300 a piece to install new Toyos, I was done with Toyo (paying too much for their name). I haul a fairly heavy trailer for camping (12,000lb). I travel on off-road gravel roads great traction. The sidewalls are great, heavy duty with durable technology. Excellent traction on wet roads and they are definitely quieter than Toyo AT. cooper AT3 LT took little weight to balance out. I am really happy with Cooper tires way cheaper heavy duty, quiet, great traction and Made in USA.

Rated 5 out of 5 by from A/T3 LT I had these installed on my 2015 3500 Ram Dually about 2 weeks ago and so far all I can say is WOW. I had H/T3's on before and thought they did a good job but I actually think these new ones are even quieter on the road than the HT3"s. They handle nicely. I have had a chance for adverse weather yet so stay tuned.

Rated 5 out of 5 by from This tire is affordable, Rugged, and Beautiful. I have had these on my chevy express 3500 Ext. van for Two months and thoroughly enjoy everything about them. They're quite, look like an off-road tire that costs 300 a piece. I couldn't have made a better purchase at 125.99 per tire and then a 70.00 rebate on top of that. I'll never buy a different tire, then COOPER.
