My question is I have S637 tires that are 12/15 dated with lots of tread so what’s the usual life span on these tires? Also they list 110psi on the sidewall and I’m running 80psi. Should I air them ...
I have 15,000 lbs. on my triple axles, and run the Sailun S637 at around 95 psi. Any more than that translates to a very rough ride in the trailer and things really get thrown around.
I tried running 110 psi at first, but the trailer rode horribly. I've lowered the pressure 5 psi at a time until I've reached the best compromise between carrying capacity and smooth ride. So far so good after 5 years and 20,000+ miles. The tires look great with no excess wear or odd wear patterns.
