tyre weld for punctures - any good?

mutley74

Asda have the Tyre weld cans on offer for £3.

Are these any good for punctures?
I know some new cars come with a glue inflation system to deal with punctures to save carrying a spare wheel, but is it worth it?
i heard that if one sprays the stuff into a wheel then the wheel cannot be repaired and used again.

welcome any views.

(also Asda have Redex stuff for engine addtive on offer - again anyone used this stuff?

Not as good as having a spare. The tyre might be too damaged to be fixed with gunge or the damage is in a place the gunge can't reach and even if fixable it may not be safe to drive on it.

I've used tyre weld for years on and off.

It'll fix anything, I've even fixed a gash in the sidewall, but I had to take the wheel off and lie it down for it to work.

It messes up the inside of the tyre, and is so hard to clean off properly most lot of places can't repair afterwards.

You can't put a tube in either, as the tube sticks to the tyre and will wear through.

But if your car hasn't a spare, it'll get you home.

im against these things because a modest puncture could turn into a catastrophe if tyre blew out further down the road because the foreign object had been floating in the casing cutting cords as you drove
you would also need a tyre inflater too if tyre goes cold flat

Another point to remember is that most tyre depots won't repair a tyre after tyre weld has been used on it.

If you read the can of tyre weld it says that it can only repair a puncture on the main tread, and like SB said you still need to inflate the tyre after using it if it has gone flat. I think its pretty irresponsible of manufacturers using this stuff in replacement of a spare wheel TBH.

A can will inflate your tyre though. It doesn't need any other source of air.
And it only repairs the tread as that's where the foam normally runs.
It you take the wheel off, it'll glue anything shut, even a tear in the sidewall.
I wouldn't advise driving on it, but it's better than dying at the side of the road in winter at midnight.
It's not a new product either, I was using this nearly 30 years ago in one car I had, that had no spare then.

I think Mythbusters had a better idea ... cut a couple of holes in the tyre and fill it up with straw.

Seemed to work well and doesn't mess the wheel up afterwards.

Manhole cover worked as well in lieu of a tyre, although why you'd have a heavy-duty drill and welding gear and no spare I'm not sure

In answer to the original question, I think they have their place. If you get stuck in the middle of nowhere in the dark on a twisty country road with folks passing at 60, I'd be wanting to be out of the way as quickly as possible and the tyre be damned. I may pick a couple of these up myself in addition to the spare as a just-in-case.
