Running on a 32' flatbed tandem dual flatbed farm trailer. Couldn't be more pleased,they are far superior to the "blowmax" 10ply. These, the Hercules H-901 and some others are one and the same just different branding

After discovering that my beloved hankook F19 was discontinued I did some research and settled on these. Very high quality and very similar to the Hercules H-901 but at a better price 2nd set on heavy Easley stock trailer and couldn't be more pleased

I have a 2016 Crossroads Altitude Toy Hauler and I went thru 12 tires before I got Sailun Tires in 2019. They are very well made and have plenty of tread left. Ordered a set of 4 to replace the ones on the trailer when necessary, (figured they won't get less expensive)

Love these tires on my fifth wheel! They wear evenly and provide an extra safety factor over the "E" load range tires originally on the trailer. Additionally, I was notified of a recall on the previous set I purchased. Sailyn was easy to work with and quickly assisted me in obtaining replacements and installation. I'm sold on the tires and the service.

I won't run any other 14ply trailer tire thats on the Market. Have been buying the S637 for over 7 years on several different trailers. They last longer then the Expensive name brand ones.
