How much air pressure do you run in Nitto555 20 inch tires? It says on the side, do not exceed 40psi to seat the bead and then has a max pressure of 50psi. Discount tire put 30psi in them and they look under inflated to me. Also I have TPMS sensors, will they be damaged with a higher air pressure?

 

Mine are at 32psi, right now and I was told don't go over 40.

 

I run 28 PSI cold on the "around town" street just to soften up the ride a tad. On a trip I would pump them up to 32 PSI cold.The ride is compromised anyhow with 19s or 20s.........

 

That's cool, just wanted to make sure they were not underinflated. Made me a little uneasy with only about 1 inch between the pavement and my rims.

 

Ah, well, welcome to big rims.

 

I have mine at 32 also.

 

I keep mine at 35
