Hi all, i have a 1987 TRX200SX and i just got new maxxis tires for it. It says on the tire to run atv specified pressure. My quad says to run the rears at 2 and a half psi. that seems really low. Can ya help me out?

aditional info:
Tire size: 20x11-8.00

 

Tire pressure is based on the weight of the quad more than anything and the weight of the rider. 2 1/2 seems low but may very well be the pressure that's right for the quad. Owner's manual is best source.
