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 !

The aspect ratio will definitely skew your numbers. the diameter is the key. If you go too big, you will get some scrubbing. Here is a calculator that may help!
