Is this normal wear on a tire?

I was looking around the garage and has some extra tires around, this one looked good, but I saw these little cracks on it (center right), is this still good or toast?

Check the date of manufacture. Like the article KBear posted says, it's there is no best before date as there's so many factors that contribute to the deterioration of the rubber itself. But regardless of the amount tread left, I'd wouldn't drive on tires past 7 years of age.



I didn't know an investigation into the cause of the accident that killed the actor Paul Walker revealed that the Porsche Carrera GT in which he was riding, had nine-year-old tires. Hockey pucks on a squirrelly Porsche like that is a recipe for disaster.

Tire looks well worn, 7 years old, visible cracks, probably not worth cluttering up your home with this tire.
I had a set of 7 year old tires on my Sunday driver that had cracks like that. Lots of tread left, but not worth the risk. I bought new ones.

I once had a two-year old winter tire that wore in a checkerboard pattern. No shit, it had raise and depressed areas arranged like a checkerboard. The three other matching tires were fine. Any idea what could cause that?
I put it down to a manufacturing defect because I don't think any part of the suspension could cause such an unusual pattern.

Did you know that those long tire treads we frequently see on the highways come from tires like yours? :sad:

It's called scalloping or cupping. It can be caused by a worn out shock or an unbalanced tire.





it's pretty much down to the wear bars anyway.
Looks to have about 50% tread left.

Actually, they're typically from transport truck retreads. The OP's tire is a long way off shedding its skin.

Did you ever end up replacing a wheel bearing on that corner? Sounds like that or a ball joint causing a weird harmonic vibration

Hmmm. Maybe an unbalanced tire. I don't think it was suspension because I rotated it and it continued to get worse. The summer's never exhibited that behaviour either. Still, I got three winters out of it before selling the car.

The "alligators" you see on the road comes from retreads on trucks. Happens in summer when tires get hot. I never use retreads.
