Last year, when I had my winter tires assembled, I was told in the friendly workshop that I had to get new summer tires next year. Now I am about to buy, but I just measured them again. The tires all have at least 3mm profile on them (Hints approx. 3.2; front about 3.5). Now I wonder if I can’t drive the tires at least until summer and if that’s worth it. I don’t want to take any risk. ut 3mm are already somehow borderline ok, then I buy new ones. Just if the workshop recommends a new tire, they do not do it completely unselfishly. So what do you think? Change or still drive a little bit? It is by the way Continental Conti Sport 3 225 45 R17
