Have new 06 monroe gmc with 500miles on it. It came with goodyear 225 r70 19.5s. Does anyone have any experience with the michilen 245r70 19.5s ? It is the regional tread, I know my dealer will have to re program the computer going with a little larger dia. Will my torke and fuel mileage stay the same? My last truck a 03 3500 rode and handled alot better with the michilens! Dont want to make the investment unless i hear from some experience first, thanks for any feedback, Truck does have air ride.
