out driving today and picked up a screw in the just off centre of the tyre(18 inch rim) it wouldnt be so bad but the car is only 5 weeks old and only done 800 miles.can they be repaired or is it a new tyre????might be wrong but i have heard you should not repair performance tyres?
I've had three or four repairs over the years. They put a patch on this inside of the tyre and vulcanise it.I have done 170mph several times on repaired tyres. Not an issue for me.

thanks guys for your fast responses the beers will taste that bit sweeter tonight knowing i wont have to fork £135ish for a new one.the strange thing in 6 years of owning a michelin equiped boxster i never had a puncture yet these are bridgestones and i still dont like the ride on them
I would never ever attempt to repair a tyre on a performance car despite the fact that it is very tempting indeed given the price of a new pair but I think the risk is too big for something to happen. Just went through the same thing last week picking up a nail in the thread of the rear 305 Bridgstone Potenzas. Can recommend Elite tires (no connection) who I got recommended on here last week. Came out and changed the pair without any fuss.
The patches have a rubber bit attached which sticks out like a hard on. Think they drill the hole to make it true and the correct size for the "c0ck" then apply lots of glue, shove the thing in and pull it tight through from the tread side then the patch bonds as you would expect on the inside - had one done recently with nail in one of my new ~470 quid rears - I'd be confident the repair is good as new 
This topic arose on pistonheads a while back - then the guy who sat on the british standard board for tyre repairs (or something along those lines), who also happened to be a PH'er, showed it was as safe thing to do as putting a new tyre on [except in extreme circumstances].
That said, if you feel uneasy about it (guess sometimes no amount of reassurance makes you feel safe) then its no use destorying smiles per miles of your PJ - just get a new tyre on.

You can also safely repair punctures in areas that most/all 'forum experts' state are irreparable. Proper vulcanised repairs are not available at tyre bays type retailers, in fact: most of these places seem to be completely ignorant as to their existance.
Im sure they are aware of them, I suspect they just are being greedy and trying to sell new ones!Sometimes the wait puts people of as they have to be sent away for a major repair, what we do is keep a stock of loan tyres especially for this situation.
these guys are routinely used by my dealer and successfully plugged a nail hole for me

Like Soovy, I have repaired a tyre and driven at 170 mph, but I wouldn't do it again...
For the sake of £150 (or less) I would rather not be thinking about it whenever I pushed the car - especially on track. Also stories of insurance assessors being paid big bucks to find reasons not to pay out would bother me if I was unlucky enough to have a prang with a repaired tyre on the car.
At least you only have to buy one as the other side is barely worn. When I had mine repaired the alternative was two new fronts as there would have been too much difference between the two.

Perfectly safe to repair up to a 6mm diameter penetration in the tread of any road car tyre, subject to, as correctly said earlier, the tyre having no secondary, particularly runflat, damage.
A few weeks ago my 911's left front deflated in the garage. I knew it was fully inflated when put away so no worries. Wheel off, tyre off, repaired and back on in a couple of hours. Fortunately for me, I can do this all myself, so don't run the risk of being misinformed or sold a new tyre, when it's unecessary.
I find it odd that Porsche refuse to condone repairs, except that I know they are covering themselves in case of a poor repair causing an issue. Most, if not all, of the tyre manufacturers approve the limitations and conditions of BS159, which sets repair standards and permits the type of repair earlier described.
No problem at all... with a proper bonded mushroom inside it... so long as the damage is limited to the tread area...
Sidewall damage from debris, kerbing, chunks out of it, or driving home on it can result in a replacement.. but normal nail induced tread repairs no problem...

Have had repairs done to tyres in the past. By well-known, large chain type places. Last one was done while on holiday, in Shropshire, about a year ago.
The tyre was a front on on my 944. Tyre was inspected carefully, the repair done, balanced, receipt for work issued. Since then I have done well over 140 on it (it's not as quick as a 911!) and I have full confidence in it.

If I did get them repaired, despite all the safety assurances, I don't think I could get it off my mind while doing 200 mph (or any boy, this would hurt speed) on the German Autobahn which would degrade my concentration. :-(
I've said this before but it's worth repeating:I challenge anyone to show me evidence or proof of a properly carried out repair failing. It doesn't happen.
Now if you want evidence of badly maintained (low pressure, worn out) tyres causing problems, that's a different story.
