We are taking a trip tomorrow (11 hours) and want to get optimal gas mileage/comfort that we can get. I just checked our tire pressure (mind you we just bought this van not long ago) and we have 40psi, 35psi, 38psi, and 32psi. The van says 35psi on the door but was wondering if I pump the other 3 tires up to 40 will that hurt my mileage? I know it will effect my comfort as it will not have as much bounce. The tires are rated for 44psi max.
Thanks!
