Currently on my second year with Sailun S637 ST 235/85x16 tires.. Cold inflation 105 psi.. Weight of my fifth wheel around 13K.
Tow speed - steady 62 mph
Tire Temp of all four tires - depends on the outside temp and if sun is shining on the tires..
.. I usually see around 20 to 30 degree temp difference on the tires versus outside temp
Tire pressure - all four tires build up 10 psi over the cold inflation within a few miles of towing
.. last tow the average temp was 80 degrees and tire pressures averaged 118 to 122...
My high temp limit is set to 145 degrees and tire psi at 90/130
My previous 14 ply tires ( Not Sailun ) were run for 7 years 35K miles and the temps and pressures were around the same as the Sailuns
** I do not tow in 100 degree outside temps and wont... too hard on the truck let alone the fifth wheel
