That is always a difficult call. I am a design engineer and a 40 year plus hotrodder, and you know what----I still think the best way is either find somebody else running the tire/wheel combination that you like, and borrow a wheel for a test fit, or find a wheel in the 14" size and bolt circle you need and try a few different "junker" tires on it to test for fit. Sorry I can't give you a more precise answer.---Brian
