I just installed 18 inch rims on my Focus. I have no experience with such low profile tires. Should I still run Fords recomended tire pressure settings? I am using 215 35 R18 Nitto tires
I disagree, the maximum pressure on the tire sidewall is just that, its the absolute maximum that can be used in the tire. It has NOTHING to do with what is appropriate to actually use. Its a really bad starting point to suggest!I always run 2-5psi less than the tire max spec. If your new tire spec is 50-60psi, the Ford 34psi spec is too low. You will get too much flex in the tire and wear on the edges. You live in a hot climate, so I would go somewhere in the range of 5-8psi less than max when the car has been sitting since the pressure will increase as the tires heat up.
