Don’t be lazy like me and do it for the first time since you put “new” tires on the back months ago.
My fronts were over the recommended PSI, backs were under. One was at, wait for it.... TEN psi. How that happened I don’t know, I imagine when one of my lovely classmates at tech school volunteered to check my tired pressures and fill them. It never looked low though, which is strange.
I imagine I’ll be seeing better gas mileage and a better ride now. I know the slight pull to the right is gone now and the wheel returns to center easier.
Also, German’s gonna brake dust. I guess I should wash those, eh?
