Just bought a 2000 Wrangler sport. tires are 30x9.5x15rim. Owner says that converts to 235/75/15. correct? I live in New York and would likely go to Mavis tire center. The site doesn't have 235/75/15 for the wrangler. Stock tire was a 225/75/15? Im looking for a tire for regular street driving and some snow--no off road and minimul beach travel. Anyone have any suggestions for a tire from Mavis in NY for these driving conditions? thanks!
