The Sailun S637 tires are generally well-regarded for their performance on RVs, motorhomes, and heavy trailers. They offer a good balance of durability, comfort, and value, often outperforming more expensive brands.

Overall, these tires seem to be a reliable choice for most users, especially those prioritizing value and performance in non-winter conditions.
Positive highlights
Excellent performance and handling in various weather conditions. Smooth and quiet ride. Great value for the price compared to more expensive brands. Durable construction with steel belts and sidewalls. Good traction and stability, even with heavy loads. Improved ride quality over some OEM tires. Suitable for long-distance travel and highway use.
Negative highlights
A few instances of premature tread wear or separation. Poor performance in snow and ice conditions reported by one user. Slightly larger size may cause clearance issues in some vehicles.

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.
Sailun's S637 is a regional, all-position commercial tire that's designed to offer drivers exceptional stability.
Features & Benefits
Tread is designed for commercial use
Black sidewall
Tread design reduces rolling resistance to improve fuel efficiency
An all-position, regional tire, the S637 from Sailun offers commercial drivers improved traction in wet conditions along with a prolonged tread life. Five extra-wide ribs increase stability at all speeds, and the S637's tread groove wall improves traction while also reducing irregular wear.
