It's time for new tires on my Ranger and i'm having a lot of trouble finding tires in the current size i have. They are P215/75R/14". I know i could put 225/70's on it easy enough, but i really prefer the 75's. So i'm thinking about obtaining some good used 15x6 or 7" wheels and putting 215 or 225/75/15" tires on it. what i'm concerned with is tire clearance on the front end, and how much, if any, will it throw my speedometer/odometer off? My Ranger is a 2 wheel drive. what irks me is Ford put this size on the older Ranger's and the Aerostar van's. There has to be an awful lot of them on the road yet.
