Hoosiers cracking

[BILL]

Is it normal to have a crack around the middle of the sidewall on an r6, tires are about a year old?

Left outside in the sun, yes. Stored inside in a garbage bag, away from sources of ozone, probably not.

My very used 2 year old r6's ended up like that, but only cause they were mounted on rims, left on the car and outside exposed to the elements. I signed off those tires as "trailer" tires after the 10th heat cycle and once I saw the cracks there was no going back to "race" tires.

I've noticed "cracks" in the sidewall in the last couple sets of Hoosiers I've purchased, but they are not really cracks. Looking very closely you may see they're tiny ridges left over from the tire mould during production. If that's what you have don't worry about it. If you really have cracks and can see gaps, I'd take them back to the distributor or contact Hoosier directly to report it.
