I have 265/75 15 tires on my 99 Ranger that came stock with 235/75 15s. According to the calculators on this great site that means 1.7 in more diamiter . The ? is would Truspeed or similar product help with mileage,performance etc? I know this size tire was an option for my truck when new but I assume the electronics are still working on the old 235/17 as far as speedo,shift points ect.Thanks Rocky
