I run a 185/70 x 14. These are almost the same diameter as the original 165/80 x 14. This is what I run: http://www.walmart.com/ip/Douglas-All-Season-VSB-Tire-185-70R14-88S-SL/49021602 I figure that the tire will dry rot before you tread wears out. I would not go wider than 185 on the standard 5 inch rims. James. _______________
