The tester did mention that the inside of all the tyres are wearing more, the tyres have covered over 20,000 so probably showed more also mentioned the cracking, which I had on the previous Bridgestones, I am on Yokohamas now, do you think the wear is normal I am thinking it is due to the camber, he did not seem concerned anyway, also my car did better on the emission test than it did last year, manual idle Co was 0.18 today it was 0.05, 0 HC today, 2 last time, do you think it has to do with engine temperature being hotter this time.
