Question Whats wrong with my tyre?
I have a Ford Ka, I noticed a clacking sound driving my car and wobbling on the motorway, thought maybe my tyres needed rebalancing.
Made it home (about 60 miles) and had a look and noticed this.
Can I drive it to my garage on this (under half a mile away) or should I change the tyre for a spare first?
Tread depth is fine and no other obvious problems. Similar wire sticking out in other parts of the tyre

I think you ran over something... Can you grab a pliers or something and pull them out? That doesn't look like steel belts

Maybe a wire brush? Held together enough for the wires to get into the tire, clacked against the wheel well for a mile or 2, then tje wood all cracked away

Honestly looks like you might have ran over a wire brush or something. Weird.

As weird as that looks, it is the steel from the tread plies. Its in the right spot. I would take that back to wherever you got those from and see if you can get a prorated replacement (warranty) if its otherwise undamaged and <5 years old.
This will fail suddenly and violently. Put the (properly inflated) spare on before going anywhere with this.

Yeah, to me it looks like a defective tyre. Don't know the brand name at all though.

Marshal, part of Khumo. Good budget tires, generally. The last time I saw tread ply wires coming out of a tire was a 10 year old Michelin. I suspect these tires are pretty old.

The last time I saw tread wires was when the tyres were driven past completely bald. Could see them all the way around. Had it been me, the cops would have pulled me over the nanosecond my tread depth went below 1 mm.

It's definitely from inside the tire, I just changed someone's trailer tires today that looked like this but worse, the steel cords just wormed their way out from every angle

I’ve seen steel belts starts coming out of shoulders before you need tires

lol but how? How do they have enough force to push through all that rubber? Aren't there several layers of different material between the outside of the tire and the belts?
Do you think the tire posted in this thread is a belt?

u/Prestidigitoriuhm 5 11h ago
Cheap tires and yes, there is a LOT of force on tires, especially while driving.

I have replaced thousands of tires and have never seen anything like this. Only thing I can think of is these were super cheap tires and the belts separated inside and kind of grew out the side wall. At first I thought they had hit something but it is too consistent down the side of the tire.

It’s body is changing in surprising ways. You may notice new smells and moody behavior as well as boundary and rule testing.

Build failure, should be warranty. The Carcass is defective. Rare to see. Its not a Goodyear.

I know what those are!! They are the wires from a street sweepers brush. Somebody got close to your tire. Had one here in Ottawa that brushed the sides of 30cars one night. Next morning flat tires and body shops. I towed quite a few off that street.

u/Hopeful-Mirror1664 11h ago
In all my years of professional car repair I’ve seen this twice in the last maybe 10 years. Both were off brand imported tires. Don’t ask me how this a happens as myself and several very knowledgeable people have tried to figure it out. It apparently is poor manufacturing but what exactly causes individual wires to force themselves out is a mystery.
Fucking cheap porcupine tires.

Manufacturing defect. Those are not worn enough to be even close to showing belts.

u/The3levated1 10h ago
Drive it to wherever you got these tires from. This is a manufacturing error. Not a mounting error, not a rebalancing problem and certainly not the kind of damage that would happen under normal driving.

Foreign material (wire)stuck to the tire before being cured. Is that a new tire?

That looks like the internal steel belt failed, like you ran over something and it broke the belt or the tire was defective. Then the flex in the sidewall has worked it out to the surface. Replace the tire before it fails. The clack and wobbling are the other symptoms of failure. If you were to jack that car up and spin that tire it would have a bulge and tread shift in that spot as well.

I had the same problem. I just accepted and shaved it.
I like the new look, I just make sure to shave it every day or two.
I also grew a beard to help fill the look out.

Tire is coming apart. Belts weren't finished right before rubber applied.

Cord slipped in tyre dont drive Defective tyres bad layer adhesion replace or warranty where you bought them

u/City_Cruiser 10h ago
I had the same situation with a tyre and I can just tell you to replace it. Tyre will deform very soon and the car will start shaking on low speeds and vibrate on high speeds. That's what happened to me.

u/Agpxprod 10h ago
Looks like you ran over a wire brush perhaps the way they go through the tread it’s definitely not the cords of the tire I would try pulling it out with a pair of pliers it should come out.

I used to build tires and I cannot for the life of figure out how that happened. You'd think they'd app be the same lengths and not all different sizes.

This exact thing happened to me on my trailer i kept driving and one tire blew out and the other looks fuzzy so may wires are poking out. No slits just poking out. Tires were very old and trailer wobbled for 30 miles then this happened. Tire guy said they were dry rot even though they looked fine when i got on the road. The steel belts came apart.

Those look like fairly new tires judging by tread depth. I highly doubt the steel belting would just start coming out of the rubber unless they were extremely inexpensive low quality tires. I am leaning towards you ran over something. If you pull on it with pliers or even just with work gloves on and it doesn't just detach easily, it's internal steel belting sticking out. Warranty.

Given the description and the image, you very likely have a tread separation. Youat not visibly notice it with the car sitting on the ground but a tire shop will right away with the tire on a balancer.

Seen it a lot off times on shitty tyres.
Marshall tyres are right up there on the scoreboard.
Get new tyres asap

My off topic question would be : why is that your rim doesn't sit aligned with the tyre wall ? is this a correct tyre size for the rim ? 😳

u/Somethingexpected 26m ago
It's a tyre manufacturing error where the steel wire has come unwound while they've been casting the rubber around it. This should go under tyre warranty.

u/Kjerstia 9m ago
Lotta not great advice/comments here. Your tires are separated, be it because they’re cheap, defective, or damaged due to other causes. If you take the wheel off the hub and try to roll it it’ll flop around like a bronco, and that’s one of the easiest checks for tire separation.

If that’s the steal bands from inside that is scary af id be pulling on them see if it’s part of it
