Thanks for the reminder. I had thought of maybe jumping up to a 15 inch
wheel, but wasnt thinking of fuel mpg. I think I am going to stick with the
235 60 14s im running now. I also have a set of 4 225 70 14s that need rims
or that need a new home to make room in the garage. My handling definitely
improved with the wider tires.
