Run flat puncture plug repair within the tread area ?
Discussion
I was in Germany last month and had a puncture ran it for 10 miles to a garage they were unable to source a replacement and used this system to repair the puncture without removing the tyre and said it would last the life of the tyre.
Back in the UK with no issues I did some research looks like a quality product rubber fuses vulcanises to the tyre rubber.

The plus system has a slightly lower risk of future leak and involves removal of the tyre the standard system repairs the tyre on without removal of the tyre.
Is it more dangerous to have a nail or bolt in your tyre sealed ie not leaking or equally are dangerous to have a plug repair?
Obviously if the run flat has been driven for a long period then the side wall may have been damaged.
But if it’s repaired using these high quality plugs immediately the puncture warning light comes on is it a big deal?
Worth buying a kit?

If the tyre was repaired within 10 or so miles it'll be absolutely fine.Back in the UK with no issues I did some research looks like a quality product rubber fuses vulcanises to the tyre rubber.

Had a few runflats repaired in the past, no issues whatsoever. I will add that none of these had been drive far 'flat' just 2 or 3 miles.

I'm puzzled as the images show applying the compound to the inside of the tyre. I have had tyres fixed a few times for punchures and have been told they are as good as new. Doubt this is any different just you can buy the kit.
Yes that's the "plus" kit which requires removal and inspection of the tyre from the rim.The standard kit uses the same product without the applying the compound internally.
I think the idea is use the standard kit to get you out of trouble until you can get the tyre inspected at which time you remove that repair and use the plus kit to make a repair which has less risk of developing a leak although they told me they'd never had anyone with a standard repair come back.
My thinking is for personal use I can carry the kit to repair as soon as I'm aware of the puncture re inflate and continue on.
If I can't repair it for say 20+ miles “ie until I can get to a suitable lay bye” then still make the standard repair but get the tyre inspected when convenient whilst driving at no more than 60 mph until I can get to a tyre centre which would mean being able to continue most or all my trip.
I'd also need some sort of pump or would need to get to a service station with an airline.

Puncture repairs to Run-Flat tyres
(Minor tyre repair to the BSAU 159 standard)
The position regarding puncture repairs to run-flat tyres is muddled. Originally most tyre manufacturers stated that their run-flat tyres should not be repaired under any circumstances. The reasoning behind this was that when a run-flat tyre is punctured the weight of the car is supported by the specially strengthened sidewalls. These are designed to carry the weight of the car and withstand speeds of up to 50 mph for a limited distance. However the exact nature of the damage, the speed at which it occurred and the distance subsequently driven are all factors that would effect the internal integrity of the tyre and it’s subsequent safe use of the tyre following a repair. As these “known unknowns” represent a serious safety issue the policy was that repairs were prohibited.
Michelin were the first manufacturer to modify this directive and now most other leading tyre state that their run-flat tyres can be repaired as long as there is no visible internal damage and no more than one repair per tyre is executed. As some Michelin run-flat tyres carry a sidewall notice prohibiting repairs the company state that this should still be complied with. Consequently most run-flat tyres can be repaired, to BSAU 159 specification as long as the sidewall markings do not contradict that advice. Michelin have published their run-flat tyres directive in a question and answer form. This is as follows:-
Why may Michelin ZP be repaired?
We have examined many ZP tyres after they have been punctured in order to establish a position on reparability. This statement is the result of considerable study to ensure that ZP tyres may be repaired safely.
New Michelin ZP tyre lines, such as PRIMACY HP ZP, are repairable once and once only following the same rules as standard car tyres such as Michelin PRIMACY HP. Michelin have prepared this statement which dealers should follow when dealing with the repair of ZP tyres. However, it is the dealer’s responsibility to decide whether an individual tyre is repairable or not.
What about existing ZP versions of tyre lines such as Pilot Primacy, Pilot Sport PS2, PILOT Alpin PA2?
Existing ZP tyres from tyre lines such as PILOT SPORT PS2 / PILOT PRIMACY / PILOT ALPIN PA2 are still considered NON-REPAIRABLE when, “Do not reuse or repair the tires after a low or zero pressure operation” or equivalent is written on the sidewall.
Pirelli on the other hand adopt a completely different approach and state that their run-flat tyres should not be repaired under any circumstances. Their directive is as follows:-
After low pressure warning is shown, the condition of the remaining tyres and the TPMS should be immediately checked by a specialised dealer. (Such as etyres)
A tyre should always be changed and not repaired after a loss of pressure, as it is not always possible to establish the time and conditions under which the tyre has been used with insufficient inflation pressure.
Damaged Run-Flat tyres, or Run Flat tyres that have experienced a loss of pressure should be immediately replaced with another Run-Flat tyre of identical size and service description (Load Index and Speed Code). Pirelli recommends that a tyre of a different type, or which contains a different load index or speed code, should never be mounted on the same vehicle.
After a loss of pressure, the rims should be inspected to ensure they haven’t been damaged. Damaged or deformed rims should always be replaced prior to mounting a new Run-Flat tyre.
etyres’ position on the reparability of run-flat tyres is that we will comply with the official policy of the manufacturer concerned. We will therefore carry out minor repairs to Michelin but not to other brands. If the position of other manufacturers changes will comply with whatever recommendations they may make.

This is also a cheap option and I can confirm has saved me a couple of times. No need to remove wheel or tyre just load the device and insert.
