I also wondered what you folks think about DIY tyre repairs like this: http://www.safetyseal.eu/en/products/safetyseal-tyre-repair-external.php


But these state that they are tested by the TUV to 300kph and also on run flat tyres....


I have used them a couple of times, apart from not being able to inspect the tyre from the inside for damage I see no reason not to use them....

Very debatable subject, due to the many Manufacturers fitting their much loved RunFlats---which is great News for the Tyre replacement market.I have UltraSeal solution in my Falkens on the ZMC, second set .The Multi Billion mile history-GreyLine- of this product in USA, and many other countries  including UK,s  Multi Nationals says it all.

B7 has that Old timer solution----------A SPARE wheel.Wink If you need to change a flat.

Unless the  deflating tyre is on the Front, when you can feel an increasing load on the steering, you wouldn't have much warning of a tyre starting to deflate.

 I had experience of a slowly deflating rear tyre on my Z3, and even though I was cruising at about 75/80 mph with lane changes, and I had no idea of what was happening.  When I stopped for fuel outside Boulogne I could smell hot rubber, and was surprised to find a totally wrecked rear tyre. The torn sidewalls had folded neatly around the rims, and had protected them from damage.

Finding a new 245-40 X 17 on a Sunday morning in France - particularly a Falken - would have been virtually impossible, so I had to drive home - over 500 miles - on the spacesaver spare, which took ages, but was otherwise without problem.

The tyres were almost new, and I had checked the tyre pressures at Dover while waiting for the ferry, but the next morning found the cause to be a small nail, probably picked up in the Dunkirk ferryport, which is quite scruffy.  It was the type of damage which Puncturesafe/Ultraseal would have sealed easily, but  I had delayed treating the tyres  until they had covered a few miles to check for any balance problems . . .

A Z3 is not just for Christmas - it's for life!

Clearly, if the tyre has been run for any distance whilst deflated you will need a new tyre regardless of whether it is standard or run flat, however, we have probably all seen the screw/nail in the middle of the tread and then had to go and get it repaired. My question is whether you would be happy with doing the repair yourself?

The British Standard describes the tyre being removed to check for internal damage, but I doubt f there is very often any internal damage if the tyre has remained inflated, indeed, if you were using Puncturesafe you may not even notice as the object that caused the puncture may have come out whilst driving.

So would you use one of these kits to repair your tyre at home or at the side of the road?

Well

As someone who's been involved in the regulations as written in the British Standards document, I wouldn't use these string type repairs under any circumstances.

From our testing, the only safe and reliable repair is a proper plug type mushroom patch, and only if the damage is within the repairable zone and to hole isn't any bigger than 6mm. These "string" type options don't block any dirt or water ingression into the belts which through time can lead to anything from the belts distorting to the whole tread belts coming away

What you always need to remember with any damage is you can't see whats happened to the inside of the tyre without it being stripped from the wheel to allow adequate inspection.

As someone who's a competent amateur mechanic myself, you can't repair tyres yourself without the appropriate equipment or repair materials.

Plus you'll probably find that if you had an accident with a tyre that has had a repair that isn't to the appropriate standard you probably aren't insured..

A proper repair is only between 10-20 quid. You can't value your own safety .. Often you could do a tyre more damage by not getting it checked and repaired properly.
