Best pressure for 20" MT DRII...?
I'm going to run the MT DR2s on a 20x11. What is the best tire pressure...cold...hot?

when you are at the track you are never going to be at a true "cold" pressure unless the car has set for hours. Start with 19-20psi and adjust in 1 psi increments if you have problems with traction. 30-32 psi on the street is fine. Don't run the tires 19-20 on the street.

Just wanted to bump this after lots of experimenting the last few weeks.
Anything lower than 19-20psi and you can feel the rear of the car "bounce", which usually means tire pressure is too low. Car dead hooks at 20psi. |
