Plug a screw hole in Cooper STT or not?

I noticed a screw in the tread of one of my STTs which I think has gone through as I've lost a bit of pressure.

If using a tyre off road is plugging advisable?

Best choice is a professional repair and you will be safe and legal.

If you use something like a sticky string plug that is only for emergency use offroad and is not a legal repair. So best advice would be to get a proper repair done as soon as possible.

Sticky string type repairs do not like very cold temperatures below -20C. They tend to pop out at very low temperatures.

Thanks Brendan.

I should of mentioned that I did mean a proper repair at a good fitter who does a lot of farm vehicles. Craig Rogers

Hi Craig, one of the problems with forums etc can be to fully understand everybody's meaning.

A plug is a temporary repair. A good repair will be vulcanised and road legal.

A proper repair carried out by a trained repairer should be absolutely fine for normal road use. Part of the repair should be a proper examination of the tyre to ensure that no other damage has occurred.

Am pretty sure that the ARB Speedy Seal kits states that the use of sticky string is illegal for road use.

However can not quickly find a definitive official statement on the legality of sticky string.

However according to Tyre Association here

Quote:

d) The following ‘repair’ methods are not recognised as acceptable:-
* Liquid sealants.
* Plugs applied externally to fitted tyres.
* Inner tubes fitted to tubeless tyres.
* Inner tubes fitted to ‘tube type’ tyres which have
sustained penetrations and which have not been
repaired in accordance with BS AU 159.
* Temporary repairs.

So sticky string unacceptable but illegal???

Maybe we should ask someone with more knowledge, say Andy at AJS or Ken

I know any hole has to be plugged now , so you can't use just a patch on inside

if you use a patch the hole has to be filled , some places use a silicone style sealer in hole and a patch

best way really is to fit a mushroom plug from inside ( a patch with long stem of rubber in the centre that you pull through the hole to block it )

I know at one time the string style repairs were for off road only , not sure now

sidewall or near curve of sidewall is a no no

They normally happen to the sidewall or near though as usual.
Before by BFG's my GG's had a puncture in one of them, caused by driving over a bottle some

left in the middle of a car park that I went over reversing.
That was on the tread but near the sidewall and the tyre was non repairable, luckily if had just bought the KM2's anyway.

ahhh democracy and the games of liability we are asked to play to be legal.

I think leeds has the correct path, the ARB type plugs are for repairs in woop woop as there is no shop. But a vulcanised plug repair at a tyre dealer is the correct legal procedure. Repairs are only for the flat treaded road surface of the tyre.

The odd thing is though. After you plug your own tyre at woop woop and finish the rest of the trip over all sorts of terrain, speeds, weights, and pressures, and the tyre is holding air and working fine, the desire to go spent $50 getting it "fixed properly" doesn't inspire.

I have a mate who buys a new set of rubber for his drag car every season. He picked up a screw in a tyre early in the season and fixed it with a sticky sting plug. Probably some 200 passes were then done and the tyres finished out the season without incident.

Had another friend put 15 into a side wall hole in woop woop, long remote off track solo trip and didn't want to use the first of his two spares so early in the trip. That tyre did another 500 mile before it was eventually retired.

legal of not they are a remarkable bit of kit. My Defender and travels
