Tire Pressure for aftermarket 19's?
 

What would the proper tire pressure be for a 19" tire? I know the stock pressures are 35psi for the 18's and figure the common sense thing would be to INCREASE the pressure of the 19's (since the sidewall has decreased).

Does anyone know what tire pressure TOYO recommends for a 255/35/19 and a 275/35/19?

I put mine at 35psi for my Volk GT-7 19in. I have Toyo T1-S tires. I read somewhere either on the rim labels or the tire labels that you should fill them up to the recommended vehicle tire pressure. Can someone correct me if I'm wrong?

Sup,

I'm running 245/35/19s and 255/35/19s Toyo T1-S and tire pressure is at 40 psi. Whatever Infiniti recommends is sorta thrown out the window after going +2 sizes (from 17's to 19s). I wouldn't run anything below 40 and check the tire pressure about every 2 weeks.

anymore input on this?

no kidding. I figure 2/3 of the regular posters on this Wheels, Brakes, Tires and Suspension forum have aftermarket 19's or 20's. Come on ladies, hook a brother up.

I even sent an e-mail in to Toyo and they haven't responded. WHA'S UP WIT-DAT?

You should consider asking infiniti what pressures they are using on the 2005 coupe with 19s. That would be the most accurate I think.

IMO if you are worried about bending a rim, increase the pressure. I have always run at about 40psi for this reason.

the general rule is + 1 psi for every size up

i would go with the recommended psi on the tires that you have.
