Anybody know the correct tyre sizes/spec I need to look for,for an e93.I am sure as they are 18 inch M-tec wheels but seeing as my mum is 250 miles away from me I cant go out and check the size.Had a text yesterday saying as it was an advisory on its first m.o.t.Would I be right to assume as they are runflats ?.Another thing is its only done 12,000 miles and it needs four new boots ?.They dont seem to have lasted very long imo.
