Is this really as bad as it looks.. :(

Is it that difficult to work out 10% of anything and how would you work out brake performance when doing emergency testing?

The brake efficiency program on the computer.....

And granted finding out 10% of a number isn't hard, but you don't get a sidewall thickness measurement to compare a cut depth to.

I would change it, although I freely admit to not knowing much about the legalities or actual risk of it, I would change it for piece of mind.

I wonder how many of the drama queens would actually change that tyre if it was on their car; relatively few I suspect, and that's assuming they'd even notice it.

I would notice, and I would change it. (although I wouldn't have tted the curb in the first place being the driving god that I am )
I fully support free will and that others wouldn't bother.

It's worth £50 to me not to chance a blow-out, whatever the outcome.

£50 a tyre? What do you drive a wheel barrow?

[HellDiver]

I'd drive on that too, not a problem.

You can save the money you would have wasted on needlessly replacing a tyre, and put it toward a set of winter tyres for next snowy season.

Yes I know that but what happens when you do emergency testing, you could need a calculator for that. The 10% figure relates to 10% of the section width but either way it still has to reach the chords.

I've had a lot worse pass a MOT. If you replace it, somebody else will most likely end up buying and using it as a part worn tyre.

If there is no cord showing, superglue it back into place. Anyone who is near 40 will know a Superglued rubber band will hold a gymnast up.

Who else guessed it was a 'Cyclone' alloy from a 306 from just looking at the picture?

....just me then

Spotted here as well - nice work!

It's a 15" wheel in very common sizes.

Even if we say £70, i'd still rather that than chance damaging my car/person/other persons.

For those of you that apparently have no idea of the structure of a tyre, here's a nice pic.



As you can see, the main structure of the tyre is in the nylon and steel carcass, not the rubber that covers it. As long as the carcass is not damaged, the tyre will not have been significantly weakened.

Can we summarise this thus:

Some would change it OP, some wouldn't, you decide what to do!

[calibrax]

I ran over a pebble once with brand new tyres, and I changed all my tyres because I could no longer trust the tyre that hit the pebble, as it might have caused some internal damage. I had to change the others as well, just in case the 0.00001mm difference in tread between them and the new tyre might cause an imbalance that would destabilise the car under braking and kill my entire family, all my friends and everyone I've ever met.

[busta]

I don't have a problem with people saying they would change it, but there is an issue with people saying it's dangerous when it's quite likely it isn't.

A rip in the sidewall of the tyre, £60 endorsable ticket there. It's a danger, and could well lead to a blowout. I'd advise taking the appropriate action to get the tyre changed immediately and avoid driving on that one.

It's not the sidewall it's the curbing protector - it's doing what it's supposed to.
No problem but cosmetically you'd feel better buying a new tyre

Looking at the rim, I'd say it's not really doing what it's supposed to do.

no, you're talking st. That isnt a curb protector.

Again. Some think it is fine to drive on, and some would leave it. You pays your money and takes your choice.

Is it more likely the wheel has a crack on the inside and we're worrying about the wrong thing
