Looked at getting a tyre repaired today but it was ripped inside so i had to buy a new one...

BUT

Got me thinking, how safe are they........... dont they just put like a wedge in the inside and let the tyre pressure push it into place......

Mr Orange

I got a puncture repaired last august. back left tyre, (205.40.17)
have done nearly 4000 miles since then and its never gave me any bother, only cost me £4 as well

xr2i-carl

what about sustained high speed driving?

steviecossie

is it just like a tube they put in the tyre??

TIFF

No...its like a plug that goes on the inside and the pressure pushes it out until it seals

cossiecrew

haha in the drifting scene we repair them with screws lol but on the other hand tyres dont last long anyway but i would of thought it must be safe otherwise they wouldnt be allowed to do it by law

steviecossie

ahh i see now,

As a rule of thumb, the speed rating is reduced. So, a V-Rated tyre becomes an H-Rated tyre. There is only a certain area of the tyre that can be repaired too.

We have lost 2 tyres on our 1.4 Clio this year (only fitted in December), had screws in them and I replaced both. Wasn't keen on the idea of repairing, even on a 1.4 Clio!!

Wrong mate if a tyre can be repaired it will be as it was pre puncture

TIFF

I dont buy that tbh Matt.............

Matt Baxter

iTrader: (37)

whys that?
I have been it the fast fit trade for around 12 years so have done the odd repair

TIFF

Matt

I just dont think that once repaired they are as good as pre puncture tyres..........

Christian and Beccy

iTrader: (14)

I don't buy that either.

They are perfectly safe and dont alter the speed rating of the tyre, if done properly. If they are close to the shoulder, they shouldn't be plugged, they need sending away for a major repair. The fitter should always examine the tyre for signs of run flat and other damage that may cause problems before going ahead with the repair.
Its a plug patch that we use, you drill the puncutre hole in the tyre out to a 6mm hole with a reamer, then buff the inside of the tyre so its smooth, then the plug pushes through, there is a patch on the end of the plug that seals onto the tyre using vulcanizing glue, which, again, if done properly, bonds the patch/plug to the tyre and should never come off.

like matt, i have done a few of these, 10+ every day!

Matt Baxter

iTrader: (37)

Why???

say you were to sell the car with a repaired tyre how would the new owner know the tyre was repaired and not drive the car to the tyres max speed h reted 130 mph

Christian and Beccy

iTrader: (14)

I'd be interested to hear the opinion of someone that actually knows the truth.

With no disrespect, just because you have fitted 10 per day, doesn't mean that you know the truth about how safe they are.

How on earth can something like that be as strong once repaired?

Just the use of the words 'should never come off' itself doesn't instill 100% confidence.

steviecossie

dont kno if i would trust that mate to be honest

Christian and Beccy

iTrader: (14)

You could sell the car and the wheelnuts only be finger tight, how does the new owner know that? But they WILL come undone, it's just a case of when.

Mr Orange

Yep, done plenty high speed driving on motorways since then. No problems with the car or the tyre
My repair was in the centre of the tyre, not the sidewall or near the sidewall.
Was a nail in the tire that caused it.

Matt Baxter

iTrader: (37)

if a tyre could not be repaired to BSAUI59 it would NOT be repaired end of

WongRS

Completly see where your coming from there, and although i have a good knowledge of the tyre industry, i wouldn;'t class myself an expert. Although i have attended The Michelin Training collegde, completing, and passing the car tyre technical course, aswell as the truck tyre technical course, both courses cover plug repairs.
i have never had a repair come back, in 6 years of tyre fitting, and i have repaired many fast cars, that i know get driven quickly!
i can understand what you mean about it not being as strong, but would it be legal if it was dodgy?

TIFF

I know they have to meet certain guidelines....but i just dont think that they are the same once repaired........

So if you had a car with NEW F1's on and you mate had a car with new F1's that had been repaired........would you swap the tyres if he wanted to???????..................I bet you wouldnt

WongRS

iTrader: (11)

i wouldn't see the point in swapping the tyres! but it wouldn't bother me so long as i could see it was a good repair, they are alot of dodgy places that repair them badly.
EDIT: sorry, i know what you mean, they may not be AS strong as a new tyre, but, new ones are over engineered vastly, there is a maximum amount of repairs aloud in one tyre, which is 5 plug repairs or 2 major repairs.

TIFF

What tyres do you run??????????

Christian and Beccy

iTrader: (14)

Does BSAU159 not say that the repair of Z-Rated tyres is not permitted? I think it does.

WongRS

iTrader: (11)

kumho ecsta ku31's on both cars.

WongRS

iTrader: (11)

Indeed it does, but Z rated are a very rare tyre, high end ferrari's and such are usually the ones carrying that, its something to do with the tyre's construction i believe!

Not trying to start an argument at all here, sorry if it looks that way, was just trying to answer the original question to the best of my knowledge!

TIFF

I wonder why????????????????

Maybe because it is not 100% safe.



So who is going to do the tyre swap thing then........Lets see who will back up how safe these repairs are

Matt Baxter

iTrader: (37)

i wish you guys would come in to my work when you have probs with tyres


i normally have probs as to why the tyre can't be repaired

Christian and Beccy

iTrader: (14)

Also, imagine the plug that comes through the tyre, it fits tight in the hole that you have drilled, but does the glue get applied in the hole itself? It's not hard to imagine that plug getting pulled from the head of the repair 'rivet' form outside the tyre under rotational grip/force. Hard to explain.....

WongRS

iTrader: (11)

thats a fair point, but tyres in general arnt 100% safe full stop. They could be faulty, especially cheaper tyres, and you'd be suprised how common it is to get a new tyre that has gone out of shape or worse.

As i just said, not trying to argue with anyone, just trying to answer the questions

Christian and Beccy

iTrader: (14)

I only read about Z-Rated, not sure if it applies also to Y and W rated.

My RST runs Z-Rated, as I can and will do 170mph in it. There is no way on gods green earth would I do that with a repaired tyre.

The horror stories about new tyres delaminating and coming apart is enough of a risk for me without bringing in other variables.

TIFF

Thats cool.....i can see you are answering all the questions.....Cheers mate, it just got me wondering today when i went to get it fixed.

Thanks for the input

WongRS

iTrader: (11)

Sorry dude, dont quite get the last bit? but yes, glue should be applied to the hole.

EDIT: i get what your saying now, to pull the plug of the patch would take some doing, have never seen it, but i'm not saying it couldn't happen! but if it did the patch alone would keep the tyre from deflating rapidly.

I heard a repaired tyre killed Princess Di, and made Jeremy Beedle have a small hand

Can't be arsed reading the thread, but I used a puncture repaired R888 for around 4000 miles on my Cossie on track and a lot of high speed use (100mph+ for much of the Ring trips) with no issues. As long as installed correctly I see no harm in them.

Si

'Gamble with as much as you can afford to lose' is my motto. If there was any chance that a repaired could kill me, I wouldn't do it.

Using the example above, you could drive around with your wheelnuts finger tight and get away with it, but I wouldn't bet my life on it.

Its a touchy subject to be honest, but a repaired tyre is not 100% as a new one is. The repairs are good and will do the job


Mark did you need a new Pirelli tyre???
