Okay my old car is an 88 dodge daytona. It came from the factory with 185/70/r14 on it. Somewhere years ago I put on 15" wheels that are 6.5". I wrapped them with 225/50/r15 They fit fine but they're worn out and it seems that hardly anyone makes an all season 225/50/r15 anymore. Would 205/55/r15 be a good substitution? It looks like my speedo should stay pretty accurate. Any thing else to worry about?
