I was just wondering what people think i should set my tire pressure to on my 91 ranger 2wd im getting a lot of rear wheel hop. All the suspension is new back there so it shouldnt be that. I think it might be the pressures im going by the factory set pressures which is 32 if i had the stock 205/65r14


thanks
 
i run 40 in my 31s. The hop may be your balance more than pressures
 
Pickup trucks are light in the rear, some hopping will always be normal. Better quality shocks might help with it somewhat, although I wouldn't lower the tire pressure below 30 PSI.
 
I'd run it how you have your best contact pattern for wear. I run my 36" tires at 22 psi. My explorer 32's I ran at 30. Any higher and it was like riding on bricks.
 
i took side walk chalk and scribed a heavy line across my treads on all corners. then drove around the block and checked and adjusted pressure till i had the best contact. i am running 31 10.5 also. and 28 psi is the best for my truck.
