Looking for the best fit in wheels and tires for the best range wh/mi. Go me factory 22", on a new (demo) MX90D. I read that 22s are not efficient.... no kidding!!!.... I get 270 to 330 all day long on my S85D with 19" and I yet to get anything below 430 on the X with the 22" not even in town or drafting at 60mph I was able to get it below 380, most of the time is over 450 at 70-75 mph leading me to believe I may have something wrong in the car beyond the inefficient wheels. Do not need to deal with snow or ice but do have to deal with the 100+Deg heat in South Texas.
