MOT fail thread

Not so much an M.O.T fail but i went to inspect my car today and found my tyres like this.

My car only passed its M.O.T in April and has done less than 1000 miles in that time. It doesn't make any sense to me as it is only 1 patch of the tyre and on the inside shoulder. Bits of it are also loose like it has delaminated or been cut. As seen on the second picture the tyre is 100% fine on the other side of the wear mark. Suspension, brakes and handbrake are all in good working condition.

Get your tyre alignment checked mate.
 
That looks more of a camber issue due to worn bushings and possibly coupled with a worn shock.
Although the date on that tyre must be years old due to the cracking, you can see the cords through it (and it'd fail on that alone).
Edit
Just seen it was the same tyre in both pics, and it's probably down to the structure of the tyre failing due to age.
I've posted plenty of similar in this thread.
What's the date on that tyre?

Tyre is 2021 so I guess so. Got new ones going on Friday. Shocks and bushings were all done in 2021. Maybe 20-30k miles ago.

Wouldn't a camber issue cause wear on the circumference of the tyre though and not just in one area?

Will get the tracking checked regardless though.

Holy negative camber. Your suspension is not in good condition.

Get some string and drop it from the arch parallel to the tyre on both sides. Then measure the distance from the string to the tyre in a few intervals. The bad side is going to shock you!

I'd be very very surprised if that tyre was only 5 years old (check the date stamp, not that it helps in any way).

Yes.
I see that stuff all the time and it's almost always down to structural failure (bulge, tread lifting etc etc due to age).

Get a 4 wheel alignment check

It is date marked 2021 Goodyear Eagle F1. I guess they just haven't worn well. Last time it had an alignment check was 2 years ago but will get them to check it again. Structural failure does seem more of a likely cause as the rest of the tyre is absolutely fine.

It is simply the angle of my camera work and being parked on uneven surface. The camber is fine.

Sorry, I didn't mean to doubt you, and yes, they haven't worn well at all.
I did post in the tyre thread a while ago about Eagle F1 super sports that I've seen failing (cracking/splitting) after 3 years.

Normal for Conti tyres in my experience. I have heard this too. One of the reasons I went for Michelin, despite being more expensive. So far I have 22k miles from my front PS5's, although I will be changing them within the next 3 months as the inside edge is wearing and was picked up as an...

I'd still get the rear shock checked on that side as we're not allowed to "bounce" test shocks on the MOT anymore which makes it difficult to check properly, and a worn shock can cause all kinds of damage to a tyre.
I hope you get it sorted.

Not because of the position of the tyre in the image, because of the wear caused on it.

That tyre looks rather bald on the inside to me. Structural failure aside.

Have you checked the suspension geometry? If not, then you need to. I'm assuming something changed (noise/lumpy ride appeared) and that's why you checked the tyres to begin with.

I hypothesise the structural failure is a combination of increased wear and tyre age, as the opposing tyre bears the same age-related cracks but not the abnormal wear.

I don't know if you read my post or I didn't explain it correctly but the second picture shows the same tyre from 180 degrees to the other side. (Both pictures are of the same tyre) The tread is 100% fine with plenty of meat to it. Zero indication of any bad alignment wear. That is why I posted the picture as it is very strange. It is literally 1 part of the tyre that has gone bad on the shoulder. Say around 45 degrees of the circumference of the shoulder whereas the other 315 degrees of the shoulder is completely fine with minimal wear.

I checked the tyre because it had a nail in it and was about to take it to a garage to be repaired only to be greeted with that section of the tyre showing cords.

Yeah it is only in one spot. The first picture shows the damage and the second picture is the same tyre from the opposite side. Almost like the brake has been stuck on but the brakes are fine as is the handbrake. It has me really perplexed tbh!

I completely missed this^ reply explaining the two pictures. I apologise.

On that basis: it looks like the tyre has caught/rubbed on something in that area. They're goners anyway looking at the cracks in the tread (seen that you're changing them).

I wouldn't be losing any sleep over this; I'd just be grateful the tyre didn't pop at high speed.
 
Absolutely fine.
It's secure and there's no sharp edges that could injure a pedestrian, so he's good to go.
However, if the car is reg'd after March 2018 and was fitted with a front fog lights, then one (in that hole) should really be present and working.

Cheers, no I don't think there are fog lights on it.
