Well?

Sunday's little jaunt got me thinking, has anyone had any experience, good or bad of tyre plugs?

and does anyone know what speed they are supposed to be rated to?

If the tyre is fixed by way of an internal mushroom and is vulacanised, the repair will/should be good for the remainder of the life of the tyre.

If an external plug is used, then it is recommended that the speed does not exceed 30 MPH for a maximum of 200 miles. I had one of these external plugs let go at about 40 MPH after about 120 miles and it took about a third of the tyre with it.

BSI recommend that Z rated tyres should not be repaired at all, although there are a couple of manufacturers who will repair them for you, Avon is one and I think Dunlop are the other, but this recommendation is surprising given the fact that the chairman of the group owns a factory that makes external plug kits for Z rated tyres.

I am currently trialing a new repair kit which allows a puncture to be repaired externally but provides an internal repair, and very impressive it so far although I have only used it on the car to date. Once I have done a few miles and/or tried it on the bike I will be writing a review, but so far it seems to be the best I have come across!

Have used internal repairs quite a few times... (Lot of nails in car park)
Have never had a problem and have even taken repaired tyres on the track on me 996 and no probs!

Just make sure they're INTERNAL and done properly. (Hole made round, rubbed down, adhesive, etc...)

Don't think I would ever trust a repair. Too risky imho.

Especially at 197mph!

I currently have three plugs (internal) in the rear tyre of the Blackbird and I must have covered about 6,000 miles across Europe since they were put in without so much as a hiss. The tyres are now shagged through wear and tear rather than as a result of the plugs, looking forward to trying out the Avon's Very Happy

If they are done properly they are fine, and a dammed sight cheaper than a new tyre.

I'm with you on that, my life is worth much more than the difference in cost between a repair and a new tyre.

That's the problem though, the most likely way you're going to find out that it wasn't done properly could have fatal results. I'm sure it's a very small chance but this just doesn't strike me as something worth saving money on. NASA and 'O' rings springs to mind ("oh we'd never tested them in those conditions..." Sad )

Mind you I've only ever had one puncture in 10 years or so of riding so maybe I'd think differently if they were happening on a regular basis.

Unlike tubed tyres, you will not get instant deflation with a tubeless, so if it did go down you would get plenty of notice the same way as if it was a normal or first puncture.

Over the past 28 + years I have had tyres repaired on both my own and my Police bikes and never ever had a problem, what is important is to ensure that the person doing the repair is someone who knows what they are talking about, and this can usually be gauged by the equipment they have to remove tyres of the rim.

It is the external repair kits I don't trust!

T.C.

What sort of bikes have you had the repairs done on? I ask this as have you had it done on the very curved race tyres, or the squared off normal road tyre you get on a Pan E?

I know that they are particular on where the repair can be carried out, if it is too near the wall I think thy will not do it. But on a curved race style tyre what are the restrictions?

I hear what you are saying, but, just for my own piece of mind I would always go for the more expensive option.

I currently have 3 plugs in the Blackbird, and that survived a few laps around the Spa circuit Wink without any problems, I have had them done on my previous Blackbirds, GSXR1100WP, R1, Pan European and I have friends who have them in the tyres of a GSXR1000, Blade and a couple of Ducati's.

I have fitted plugs to an assortment of tyres over the years, and again I have never had anyone come back and say that the repair failed them.

The general rule is that if the hole is more than 50% beyond the centre of the tyre or the sidewall has been compromised (which you may not know until the tyre is off the rim) or the tyre is cut rather than punctured, then the tyre should be junked, but if the puncture is within these limits then it will be fine!

Hi

I have had several tyres repaired. The FZ750 has a repaired rear at the moment. The rear that has recently been replaced on the Bandit had been plugged as well (all internal ones).

Sure you can say that you are not that sure about the state of the repair and is you life worth more than a new tyre. However are you that certain about a new tyre? Is your life worth more than 100 tyres? 1000 tyres? 10000 tyres? Given the low chance of serious failure it quite possibly is around a 1 in 10000 chance, basically irrelevant.

All the best

Keith

I had the 207rr on the Blade repaired, worked fine for dragging and everything else, but no-one would fix it for me when it needed a 2nd plug Sad

Must admit I'd just get a new tyre rather than repairing one. Just my opinion

Nah, just don't know anywhere I'd trust to patch up a tyre. Rather pay the £ and get piece of mind.

My boss bought a Blackbird on an R plate when the Blackbird was only released in 1996, so this was a new bike, it had covered about 2000 miles, and the guy sold it to him. Took it out for a blast and the guy even said to him, I've had the rear tyre plugged, it wasn't until he got home he remembered and looked back and had just been doing 170mph down the M1 Laughing He got the tyre replaced straight away. Repairs are a temporary fix, on moped tyres it is not so bad, but on anything that will do over 50mph I would never plug a tyre if it was my own bike.

I got a slip for 197mph on sunday on a plugged tyre so that kinda gives me confidence that they are ok for normal road use Wink
