I would start off with around 8-10 psi. as long as it don't spin keep adding air till it does. Then maybe try it a little lower and see where it 60 fts the best
JMO ...I aint been at this as long as most of ya. I know I can roll my car out of the garage way easier with 30 psi in the tires than when it has 10. Know what I mean?
