Would I have ANY issues jumping up a size from 275x65x18 to 275x70x18 ?
Truck will be used for towing a small RV trailer (18' 4000lb).

I realize 70's are a larger tire by almost an inch, and realize it will affect speedometer actual readings, but will jumping up to this size cause issues to the transmission, handling, gas mileage ?

Thanks for your feedback, much appreciated !
