I took my Clio to the garage the other day and was told it needs four new tyres fitted as the current ones are not the correct speed (?) Can someone please explain what this means? Apparently they should be 88V X Load. The fact that I have been driving around with the wrong tyres on since I first bought the car 2 years ago from a dealer (I am the second owner) seems a bit strange. What damage, if any, would this do to the car and what are the real consequences of having the wrong tyres fitted? Thanks a lot!
