Repair a puncture, yes or no?

**Tim Falce** · 25 May 2006, 18:17 (Ref:1618843)

I have just found a small screw in one of my tyres, it is in the centre of the tread. I was wondering if it would be safe or wise to get it plugged or should I fit another tyre?
I dont really want to put a new pair on as there is a few races left on the other tyre and don't want to mix old and new on the same axle.

i dont see a problem repairing it as long as its done with a proper mushroom type patch like tyre centres usee on road tyres.

Done it! With Wurth`s "do it for youself"-kit. Worked out just fine. Tyre was on the rim...

on a road car, maybe, on a race tyre . . .never

Hmmm... dunno about the race tyre though - mine was a road tyre (because we have to race with street legal tires).

I would it as grahame said it was a proper mushroom repair. Dunno about one of those kits where you do not have to take off the rim (plugs?) they were always a bit marginal.

Zef I have your stuff with me here at the shop just got to remember to get the courier in!

My tyre repair rules -

A proper repair on a road tyre, no problem.

Anything on a proper race tyre, no way. I'd be surprised if you would even find someone to do it!

Can of tyre weld (or similar), only to get you through a race then change the tyre before the next meeting.

I had a small puncture (from a nail) in a slick tyre when I raced F750. One of the Austin 7 boys fixed it with a bicycle repair kit and popped the bead when refitting the tyre with a length of rope and a piece of wood. I must admit being a bit nervous as it was at Snetterton with the old flat out Russell, but it lasted the race and I replaced the tyre for the next meeting.

I don't recomend it though!

Yeah maybe not on a slick as I do not know much about them but I have done it in list 1a and would do it again, I really don't see the problem if it is OK on a 150mph road car which will have far more devestating consequences if it fails then surely it must be OK for a track car. Depends on the severity of the puncture of course but a simple nail hole I see no problem repairing it. Put it this way it could easy if tubeless, have that nail in there and stay inflated, you would be none the wiser. Now a mushroom repair vulcanized from the inside must be safer than that surely.

you will be fine on a control tyre and a road tyre, if the tyre your doing it on has been known to have tyre blow outs then its all a bit iffy, remember tyres work in tension, when they dont they tend to go pop

our crossplies struggle to hold reliable pressure when theyre new let alone old and repaired

when we went to LeMans few years ago one of our part had a puncture in his Elise . . . a French guy fixed it with what appeared to be string and a corkscrew, Chris being the tight ar5ed chap that he is never changed it and infact sold the car before the tyres wore out !

Al Weyman · 6 Jun 2006, 11:11 (Ref:1628383)

Thats a plug by the sound of it Zef and IMHO is plain daft as they are not legal as a road repair now I don't believe. By forcing the plug in with no mushroom behind it that will naturelly be held in by air pressure that type of repair is at best marginal.

BTW Zef did you get your clutch disc today?
