I've got 235/75R15s on the XJ at the mo', up from the 225/70R15s it came with. I've had no problems at all, apart from when turning full-lock right I occasionally get a rub on the right-hand LCA.
This doesn't bother me too much, but what seems strange is that I swear it's getting worse, as previously it would only do it if turning on a hilly junction or something, but now it's doing it every full-lock right turn.
Is there anything I can do to stop it (other than steering less sharply!), and has anyone any idea why it could be getting worse??
Cheers!
