The age worried me but they look good. Gonna put a couple thousand on them and see how they hold up. But after a little break-in they seem just fine. Couldn't argue with $800.

The tires had no cracks or anything that would indicate that it is 3-4 years old. Looked brand new.

Good friend is a Michelin materials engineer in Canada, so I pick his brain a lot. A tire that has cracks after 3-4 years would be a manufacturing defect.

Modern tire compounds will easily last 6 years of sun / weather exposure and perform as expected, and possibly quite a bit longer if garaged.

That said, he usually recommends replacement after 6 years or the wear bars showing.
