I agree, I'm really pleased with both the tread wear and the grip. They've been an awesome tyre. It doesn't make sense to save a bit of cash on a tyre that'll only do 1/2 to 2/3 of the mileage.
I think I'm fairly lucky getting nearly 20,000 miles so far. Sadly I don't get much opportunity for really spirited driving though!
In a way I should be pleased that I've got such good mileage out of them, but I still thought the cracking was a bit premature for the age. Sounds like I’ve been a bit over-worried though. Just anything tyres/brakes/suspension/steering I'm fairly cautious with.
Thanks, I really appreciate all the advice.
Michelin contacted anyway. I shall report back...
