So, I finally got my new wheels on last night.
225/35 on a 20X9 and 245/35 on a 20X10.5. I had them pressurized at 40 psi, but today Firestone decided to air them down to 31 since that is the factory spec (i was getting a broken stud replaced). It feels more comfortable now, but is it safe?
Looking for advice from people with stretched tires. For what it's worth, I drive like a grandpa, but daily the car.
