I have a 2001 Mercury Cougar S with 17" stock rims and 215/50R/17s. She's got 4 different tires on her so I'm FOR SURE getting 4 new ones very soon. Can i upgrade my tires width/profile from 215/50R/17 to say, 235/45R/17 or 245/45R/17 while using the stock rims? is it a safety hazard or anything? I'd love to get new rims but I just dont know if I can afford them right now. Thanks!
