I looked through all the old posts and it looked like you said the widest tire on a stock rim is 235/60/R15 is this correct? I have 215/75 15's on my beater 5th. 225 70's on my concert cruiser 5th and I'm looking for the widest for my 79 Diplomat. Going up in rim size is not an option as my buddy just sold me the coolest rally type rims of an 81 LeBaron. Thanks Mike
