Vulcanised puncture repair...is it safe??

[marky2027]

Noticed a screw in my rear tyre the other day and popped into my local tyre place (seems very trustworthy) who have repaired the puncture with vulcanised plug/patch. He said it was totally safe and would not affect me in any way. However I have been browsing on here today and there was some mention of speed limited to 70mph if a tyre is repaired. Is this right?? Am slightly concerned as yearly trip to France up and coming??

I have had them done in the past and never had a problem - I would always get a tyre repaired (if it could be - i.e. not punctured towards the edges).

There's no particular speed limit that applies to puncture-repaired tyres; perhaps someone is confusing puncture repairs with space saver spare tyres? They're usually limited to 80 kph.

Are you sure on that? As it's no longer up to the same standards as it was when it was made it wouldn't surprise me that it's only good enough to meet the max national speed limit. I very much doubt that a tyre manufacturer would accept a high speed blow out in a tyre of theirs repaired by a third party.

As long as its not on the side wall it will be ok. I've had a tyre repaired by plug and patch and I had no problem with it.

So have I just wouldn't trust it in a high speed run. I mean would you push 170mph on a z rated tyre that had been repaired in a car capable of that speed?

Yes, I'm sure on that. If there was some arbitrary speed limit for puncture-repaired tyres, wouldn't the repairing garage be required to put a notification sticker on the tyre, or perhaps on the car, warning the driver not to exceed that limit? When you buy a used car, how does anyone know whether any of the tyres have had a puncture repair and that they therefore shouldn't exceed 60 or 70 or whatever?

Since starting this thread I have contacted Falken's technical dept and they say that a repair would not affect the load or speed rating. I mean I am not a speed freak or owt like that just want to know it is safe at cruising speeds

Thats why I asked I have searched the relevant specs and its only very brief. I just find it hard to believe its as safe as a brand new tyre as once rubber has been cured it cannot be re-vulcanised. Therefor imo its not as strong.

Mind you, who actually checks that the tyres are H rated etc when they buy a new car/used car?

All seems to be a bit of a grey area as I have been told that the tyre one repaired is limited to 70mph when I had one done a few years ago.

As long as they are happy mate :thumb :

yep tyre manufacturers will ahppily accept that ONE puncture repair is acceptable providing its in he centre 75% of the tread of the tyre

you can repair in the outer edge but it is a specialist repair and is expensive and to be honest at that stage i would be looking at a replacement
