As most Redwoods heaviest wheel position will weigh in the 3,600 lb. plus range, to generate a 20% reserve load capacity you need to air the tire to carry at least 4,320 lbs.

@ 110 psi the load capacity is 4,340 lbs.
@ 115 psi the load capacity is 4,495 lbs.
@ 120 psi the load capacity is 4,650 lbs.
@ 125 psi the load capacity is 4,805 lbs.

I run my tires @115 psi and add at 110 psi.

My RW rides a lot smoother at 110 psi. It is noticeably rides better than at 125.

Tire pressures vary a lot between the right and left sides, should all pressures be the same or should I inflate each side according to weight
