Rear tires wearing out after 10,000 miles... any ideas?

I’ve noticed the rear tires on my 2015 Kia K900 are completely worn out after just 10,000 miles. I had an alignment done recently, tire pressure is spot on, and I’m not an aggressive driver or carrying heavy loads. What could be causing this?

Have you checked for any suspension issues? Sometimes worn suspension components can lead to uneven tire wear.

Good point. I’ll ask my mechanic to check the suspension components specifically. Thanks!

Did the mechanic mention anything about wheel bearings or bent rims? Even minor damage there can cause this kind of problem.

I’m pretty sure the mechanic would’ve spotted a bent rim. I’ll double-check about the wheel bearings, though. Thanks for the suggestion.

What kind of tires are you using? Even expensive tires can wear out fast if they’re not suitable for the car or driving conditions.

The tires are high-end and meant for the K900, so I doubt it’s the quality. But I’ll keep this in mind if nothing else checks out.

Did you notice if the wear is uneven across the tire or just one side? That could indicate a camber or toe issue even after an alignment.

The wear seems pretty even across the tire. I guess that rules out camber or toe problems?

Not necessarily. Even wear could still be caused by something like suspension sag or soft bushings. Worth checking out.

If everything checks out, you might also want to rotate the tires more often. Sometimes rear tires wear faster on certain cars.

Good advice. I’ll try sticking to a stricter rotation schedule going forward.
