Trust me Mark I do know your distaste for them, and it unfortunate that they are not willing to make things right for you. And do not blame you for not wanting ever do business with them ever again. However I have fortunate with Michelin 20k+ on the SHO and they are still going strong no cracks, had Michelins on my caddy as well and my wifes escape with 40k and all doing fine. Why that is I don't have a clue weather, climate, perhaps Michelin just a inconsistent quality control when it comes making tires. But my advice to JCL was merely economically mind mainly 2 tires are cheaper than 4 and the Michelin is a comparable tire to the continental. I know I know you will not agree with me, and I agree you have good reason not to, but with that said I've seen continentals all cracked up as well. While we may never know why this happens I bet the tire companies do, it just a shame that they wont sand behind there products.
