305/55R20 vs 275/65R20
I can't for the life of me decide which tire size to roll with here. Looks is the least of my considerations. I'm looking at MPG and torque differences. Tire diameter difference is 33.33 to 34.2". I have 275/65 on it now, but just don't know how much or if any the 1" height difference would make.
I get just over 20 MPG highway now, which is great. It pulls my horse trailer great, but would take a little more torque depending on if there is a real world difference in 1" or not.
