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

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.
