I haul my Excavator with these tires I needed the most extreme duty tire and these tires met that They have an all steel cord 75 mile per hour tire 125 PSI They are "non eco" If you buy a lot of tires that's a good thing

Bought S637 for my 5th wheel. After approximately 4000 miles I noticed one of the tires was bulging throughout the middle of the tread. It was not over-inflated. The other tires are still good. The warranty/return process is complicated. Now I tried ordering a replacement and "out of stock". Pretty disappointed.

We purchased/upgraded to these tires for our fifth wheel trailer. The stock tires had a flat spot on two of the tires and where not rated highly. Most stock trailer tires are rated 65MPH. These are rated to 75MPH, not that I always drive that speed. But we travel full time in our rig so if we have a long travel day I can push the speed a bit.

I have always had great luck with these tires until recently. over the past 2 years the tread started coming off with two different sets of tires. All axles are good on the trailer, I check air pressure several times especially on a long haul. 1st set of 6 tires I had the tread come off a tire at 12,200 miles 2nd 18,900 miles 3rd at 21,300. I decided to try another set because I had never had issues in the past. Son 2nd set of 6 tires, The first tired tread started coming off at 4,500 miles and second at 6,270

Can't say about wet, tread life, or winter traction but everything else is great. Good tires.

We run these as fronts on F550 Bucket Trucks with S737's on rears. Just bought 16 from another source; commenting here while checking pricing. Great tire especially in this price range.
