Tire size and fuel economy
 

I just picked up a 1998 k1500, it has 245/75/16 tires on it and I wnat to go up to at least a 265/75/16, will I loose much fuel mileage going to a little bigger tire? Also can 285/75/16 fit without rubbing too much?

i honestly cant see you losing that much where it even makes a difference.

Your city MPG MIGHT suffer slightly, but otherwise you'll be fine. And yes 285's will fit. Use torsion bars if needed, but stock hide height should work.

I have found this to be very helpful in deciding on tire size
