Widest width Tire, Front/Rear on '65 Dart

I had 205-75-14's on it. (26.10" High). The speedo was about 3-4 miles per hour fast. The car has had this size tire on it since dad picked it up in the 70's. I swapped the biased plys out for radials about 8 years ago.

A friend gave me some 215-60-14's that I put on it, cuz it needed new rubber, and they were free. The speedo is 10-12mils per hour fast now.

I am putting the 273 back in it, it will have a fair amount more umpf. A little more width under it wouldnt hurt.

235-60-15's are same height as the tires I had on it.

245-60-15's will probably true up the speedo, at least until I get the 8 3/4 put together for it.

Johnny, those look pretty sweet under your car. I like the profile.

PettyBlue - Curious on backspacing on the 15's? Were those on it before or after you modified the wheel housing?
