With 20k miles on the clock I need to replace the full set - (I could maybe have stretched this out by swapping the tyres Right to Left as the left tyres get more use. I guess I am happier pushing harder on a right hand bend than on a left hand bend.) The tyres are Michelin Pilot Sport 225/45 ZR17 with an "MO" which indicates a Mercedes specific tyre. I can't find anything definitive about whether the MO indicates a different tread pattern (according to one thread) or whether it is due to a different tyre wall thickness (local tyre dealer said this might be the case) or whether there is a difference in the bead seat profile on the MB wheels. There are different variants of the PS for Audi, Porsche and MB in additional to the plain vanilla PS or PS2. Can anyone give a definitive explanation as I am not sure whether to hold out and wait for some MOs on special order or simply go with the plain PS2s that the local tyre dealers have in stock.
TIA
Matt
