Just put the Sailun S637's on our 5th wheel. Went to Vegas and back last week. They ran terrific. Stable pressure, ran at very low temps. I couldn't be happier!
I just put Sailun S637's on ours. G Rated 14 ply @ 4080 lbs. each. Needed to upgrade rims to 110#. Pulls so much better than those stinking Raniers it came with.
