Was rotating the tires on the Sonata today and this one was on the front left, now on the right rear. Has a strange crack in it, was wondering what you guys thought? I think I'll continue on with it and just keep an eye on the tire. I bought the car 13,500 miles and 7 months ago and the tires were almost brand new when I got it. They're Kumho Solus TA11s. Tires are feathering slightly on the outer edges, I'll probably get an alignment next time I get tires.

Kind of strange how it looks like it stretches, not like a cut. No bumps in the tire and the others look fine.

You'll probably start seeing more of those cracks soon.
Aren't you supposed to cross the rears for FWD?

When I rotated them after 6,000 miles or so, I just did front to back. This time I did an X pattern.

Tire date code is 3315, I keep them around 35 psi which is a little above door placard. Also drive a little aggressively so that might be it.

Have a dealer look at this. It might be a known problem with a solution waiting.

That car isnt a heavy car unless you over load your trunk with junk. How is your alignment? If under warranty just bring it to dealer and complain. Make sure if they tell you that its nothing to worry about, have them put it in writing.

If you drive super hard maybe rotate every 5000 miles. I havent heard of people rotating in X patterns in a long time especially on newer cars as that can cause belt separation due to the different forces on the tires. What does your car manual state?

Did you balance tires before you rotated them? A lot of people get lazy and just do a garage swap.

I wouldn't worry about i beyond what it really is, just a junk OEM get it out the door tire. Trust me all those Kuhmo tires they use on sonatas are absolute TRASH. I know 3 other guys with Sonatas and mine took the grand prize of making 36000 miles and I ran those pigs almost bald. Everyone else's [censored] out at under 30K.
Take it to a stealer and see what line of poo he passes off on you. Maybe it will be their old standby, You didn't get them balanced and rotated twice a year mad . That's right up there with getting your disk brakes cleaned annually which is a Hyundai favorite though it is catching on with at least of the other companies stealerships as well.

I had that happen on a set of BFG Rugged Trail tires that came on my 2008 Tacoma when I bought it new. The cracks spread along the circumference, and BFG replaced them under warranty with 26k miles or so on them.

Side note: the Rugged Trail was the absolute worst tire Iíve ever had. The wet and snow traction was horrendous. Do not buy.

Do you perhaps have a gravel driveway or park in a gravel lot?

Because of the shape of the crack, I think it is either from rolling over an object (like a rock) that overstressed the tread rubber.

- OR -

There is a bit of inconsistency in the tread rubber mix.

Neither of these is cause for alarm. Just check it the next time you rotate tires - and I'm hoping that is about 5K to 8K from now.

I don't have a gravel driveway, I've driven it on a rough dirt/gravel road once for about 10-12 miles before.I usually rotate at 6-7k.

I'll keep an eye on it next time I rotate. The car is long past warranty and I bought the car used at a Subaru dealer and it came with these tires.

Last time I read about something like that it was due to belt failure inside of the carcass. But that also comes with a bump, lots of road noise, maybe even pressure loss. With a crack that small though, it could just be slight damage from road debris.

Just keep an eye on it. Make sure it doesn't bulge out or the crack doesn't get deeper. Tires will show major signs before they blow and they're more durable than you think.
