so im turning 32s on my 2.5 with stock gears and axles now. its got a 2.5" pro comp lift and the tires are going to be wearing out here pretty soon. im thinking of going down to 31s when it comes time to replace them as I don't really off road anywhere without my friends who all have stock SUVS or pickups with stock 235 65 ish tires. what advantages would I see with this switch? better mileage? I know more noticeable power. will it look terrible with my lift? should I just pony up the extra money for the 32s?
