40 gives less rolling resistance but will be a little bumpier
Question: why are your front tires an inch taller than the rear ones?
I Honestly have no idea, i bought the rims and the tires came with them, I definatley did not pick out the sizes :?:,
Is that potentially bad for the car?
And does running 40 PSI give better gas mileage as to 35 PSI?
