Have seen that there appear to be different types fitted to the cars. Would be interested to know what tyres have been fitted, to the cars and which model and which build week. Can not conduct poll on each tyre and every build date and model of car, however will start one for makes of tyre. I have Continental Continsportcontact 5, fitted to my TDI Quattro, sorry forgot BW 11. Is there a reason for the differing makes or is it just down to the stock of a particular tyre running out?
