been reading some threads on "pizza cutter" style tires, 255/85/15 or 255/80/17. right now i have 265/75/16 duratracs and since i put them on my mpg's on my 2.7 4x4 went from 21-22 mpgs down to 18-19 mpgs. one of the claimed benefits of the 255's is better mpgs because there is said less rolling resistance. anyone running 255/85/16 or 255/80/17 that can chime in?
just wondering if i made the switch if i could get back up to the low 20's for mpgs again.
