Would you have any concerns running a 450bhp lightweight on nearly new tyres that have had a puncture repair???
A repair in that area would almost certainly never just "Let Go" so you could run it with any horsepower as long as you kept your eye on
it.
Having said that, why don't you just replace it? That way you will never be wondering about that rear corner letting go...
Steve
it "should" be fine
i had one in a similar place on a car tyre bug with alot less horsepower on tap

Depends on the speed rating but I'd assume not. If they're above H then only the centre 80% with standard patch's.

Proximity to edge would make it specialist repair only depending on angle of penetration. IF repairable at specialist, then cost would have to be weighed against cost of new tyre and how comfortable you would feel about it.
I had a puncture repair there on my tintop (previa) cost £18 with the balacing etc.
What if I told you that the tyres had 7mm left and the cost to replace both with shiny new ones is over £500

If it was mine and I was repairing it, I'd do the first one but not the second. If I had to let someone I didn't know do it then neither.
Seek out a specialist tyre repairer (not just KwikShit) and see what they say. £500 or risk yours and everybody else around you's lives?

Ive had 2 tyres let go on me that have been repaired like that with a little mushroom plug. Both were on my diesel pug106, which is a very slow
underpowered car.
One tyre started to bulge where the repair was, and one went bang and fully deflated whilst driving on the motorway luckily it was a back tyre, and
not a front one
i have vowed to myself that in future i will always just buy a new tyre instead, but my tyres were a lot cheaper than £500
Cheers!
Some food for thought there!

if the repair is done correctly then there is no problem trouble is there are 2 many people in the trade that think they know what they are doing when they know nowt
No - not chump money to me... it's a bloody lot! Hence the reason I'm debating going down this route! Unfortunately, 315 section tyres
don't come cheap, so you HAVE to pay what they cost.
PS - It might surprise you how prudent I've been with my build costs on the Ultima. It's being built to a definite budget - hence the
reason it's taking so long to complete!
If I was indeed 'man of very obvious means' then it would have been finished a long time ago, and I wouldn't be farting about with
second hand engines, repairing OEM manifolds and discussing plugging tyres!

For tires rated to 130mph, you are typically allowed to repair one puncture per tire w/o affecting the rating if:
Hole is less than 6mm
Hole is between the outside grooves (yours are not).
You use a plug and patch system (combi patch)
Tires above 130mph, no repairs permitted while retaining the speed rating.
While you could safely patch those holes for normal street use w/o any worrys, I would not use them for high speed events. Certainly not a track
day. If in doubt, email the tire manuf for repair info.
Cheers.

[edit] btw, this would be a good chance to buy some track wheels/tires and just run the damaged ones on the street

(1) Both holes are on the tread area of the tyre
(2) The tyres are steel belted radials.
This type of puncture would normally be repaired by vucanising a plain patch on the inside of the casing.
During repair UK law demands the tyre be visually examined internally and externally for damage and any debris clean out from the casing.
Mushroom type repairs are not suitable on steel belted tyres because to insert them damages the steel belts and in any event the edges of steel belt
would cut through the stalk part of the plug.
Having said all that with the ammount of power you have using tyres that you could have any possible doubt about is silly.

10 rons for a full set of tyres inc spare. my!
with that much power tyres can rotate on the bead of the wheel rim sometimes the inside and outside beads do not rotate at the same rate thus twisting
the tyre hence why drag racing cars sandwich their tyres between two beads which could dammage the securing pad of the plug
im my experiance i would have refused to repair that puncture because it is not in the central portion of the tyre although i must admit if it was my
own car i would plug it and fill the tyre with the puncture repair gue you can buy from halfrauds just in case
That way if it goes which as people have rightly said they seldom do it will go down slowly a blow out is not a pleasnt thing
i cant remeber the exact reason for only repairing the canter section 75% of the tyre width but that advise came from the dunlop training rep when i
did my apprentaship
i know the tyre is going to be silly money but if you write off the car for a 500 quid tyre you are going to be even more pissed off
besides im sure somone will give you stupid money for the repaired one on good old ebay
