Tyres-sidewall repairs?

I wouldn't trust it.

tom sent this to me:

What isze tyre are they?

I'd be suprised if it was cost effective? Especially Given that the cost of a standard puncture repair around here is about £15, The last set of tyres i got was £65 for a pair of michelin Ecos. (buy one get one free - but those offers are always around and are never actually buy one get one free once you work it out)

Is the sidewall torn, or just a small hole in it. You could stick a tube in it.

Michelin do not recommend putting a tube in under any circs. not even on spoked wheels, they say use a tyre designed for a tube.

It can be done, but it's not normally worth it.

Yes...my mate used to work at a company that specialised in sidewall repairs some years ago. Provided the proper equipment is used, it should be OK. Not all sidewall damage can be fixed, large cuts for example, nor tyres that have had a load on them when flat for a long period.

They would do, wouldn't they? They'd lose a sale if people realised they could use tubes in tubeless tyres.

Using a tube 'may' lead to friction between the tyre and tube. I would put a tube in and not worry about it on an ordinary car of my own, BUT it certainly shouldn't be done by a professional on a customer's tyre.

Would it depend on whether the carcase reinforcement was damaged? Can't see how you could repair broken cords.

There's a good reason why you shouldn't.

How old is the tyre?

Even if it can be done, it may not be worthwhile.

Doh! Just read it again. 'new', that's a bit of a hint.

Ignore this....

It certainly has done on Range Rovers I've owned which previous owners had bodged in this way. Some tubeless tyres have very sharp-edged moulding lines on their inner surface.

There are two other reasons for avoiding putting inner tubes into tubeless car tyres: you are deliberately reducing the safety of the car, since a puncture will generally result in more rapid deflation; and if the hole in the tyre is not repaired, water will get in and might damage the textile or steel reinforcement.

Apart from that, and the fact that inner tubes are disproportionately expensive, rarely stocked, and many fitters haven't got a clue how to fit them, great idea.

hmmm

...unless it's some crappy old Ford, perhaps.

but to the OP: a small garage or amateur mechanic may well do daft things through ignorance, but I'd be surprised if a company would specialise in repairing such tyres if the process was intrinsically unsound. Whether it's economically sensible or not may be another matter.

By that argument they'd recommend you never repaired punctures. It's difficult to imagine how an inner tube would outperform a puncture repair.

I went into a tire place due to having a screw in a tyre and it going down. I had new tyres on order elsewhere so asked for a repair - was told "won't do repairs on tyres with only 3mm left".

They'll find any excuse to tell you you need new tyres, they also told me two others were illegal (which they were not). Useless.

Like they do on tyres requiring tubes?

I think that was most likely the fix or bin criteria.

Which is?

Don't think that they don't do that.
