Hi all,
Is it possible to get sidewall repaired ? I have a BF Goodrich mud that has a slice in the sidewall its about 20-30mm long and is midway between the tread and bead. I am not sure if its all the way through - haven't had as good look yet.
Cheers,
Pete

As Al posted they are now not allowed you cannot even run them as a spare on road as they are no longer classed as a legal tyre.
This means next time I get a set of 4wd tyres I will be buying an offroad warranty with them, this limits who I can get them from and may make the offroad warranty's a lot more expensive.
I understand this came about from a few accident investigations on Truck's, in some cased the tyre repair had failed causing the crash and when tyres were repaired and sent to Austrailia and Firestone for testing they did not meet new tyre standards.
Commercial tyres are being built with far stronger side walls now to reduce the risk of trucks tearing or pinching the tyres on kerbs loaded.

Legal disclaimer: Any information I may have provided is worth exactly what you paid me for it.
When I worked at Firestone, you could only repair a tyre if the radial plies were undamaged. From memory, the rotational plies could be partially damaged, but not completely cut. The "repair" was only to keep water, dirt etc from entering the plies and causing further damage. We then put a radial bead patch, essentially runs from the bead right up to the tread on the inside of the tyre, to help stengthen the area. Seemed to work good, mind you, this was 13 years ago.....
(jesus, how old have I got??!!) If you had a repair done, we used to buff off the speed rating on the tyre (a letter at the end of the tyre size, S, Z etc) and the customer was told the tyre was only "rated" to 120kph..... as were all retreads.
If it's purely cosmetic, it might be worth checking if it can be repaired. That was easy, buff it back a little, add some uncured rubber, then put a "hotplate" on it to cure it. That would depend on if the new reapir law is for ANY repair or for damaged plies only.
Hope this helps.
