Can this tyre be repaired and, if so, would you?

[anonymous-user]

As you can see, plenty of tread left and, other than this nail, I can see no damage.

Edited to add measurements

The nearest edge of the nail head to the shoulder of the tyre is 10mm

Without seeing it in person I would say no, it looks like the damage is too close to the side wall so the patch won't fit.

If the patch will fit then it depends on the amount of tread that's left and how much a new tyre is as to wether it's worth it.

Thanks!

I edited the original thread to add that the shoulder of the tyre to the nearest edge of the head of the nail is 10mm

I've had one repaired closer to the rim and with far less tread.

If the tyre repairer is OK with it I would be. The head of the nail may be significantly larger than the shank which would mean the hole is not that bad.

Link above gives law on area of tyre that can be repaired.I would probably say that is borderline as to if that could be repaired or indeed if any tyre shop would repair it.

That said there are may numb nuts in tyres garages so go somewhere reputable, I used to sell tyres and a guy from my supplier of part worns said he would repair sidewall punctures if I wanted.... Errr no thanks

[redtwin]

A repair shop also wants to sell you a new tyre so won't get too silly, hopefully.

In your case, a repaired sidewall meant the sale of a scrap tyre, not the lost sale on a new one.

Little diagram here should help:

Work out the area "t" on your tyre then go measuring

[crolandc]

Yep' it will be borderline,but if poss I would have it repaired and stick it on the back.

[rallycross]

It can be done but the guidelines say its too close to the sidewall so its unlikely they will offer to repair it.

I have repaired similar punctures and used on track day with no problems but for safetly reasons would not recommend it on the road.

So, according to the diagrams on etyres

repairable area (T) = 70% of the nominal section width

In this case the tyre is a 265 so that's T = 185.5, leaving 79.5 / 2 = 39.75mm as the distance from either edge that can't be repaired.

This 'injury'is 10mm from the shoulder, i.e. 29.75mm too close to be repaired. And that's assuming the hole is less than 6mm (sure it is).

Any problem with those sums?

Or, go for a different kind of repair and have a hot Vulcanised repair. I have done this lots when I have damaged tyres on my off roader. Unless you are regularly running high speed or doing track days, get it repaired

Sounds about right to me.

[anonymous-user]

Or you could do it yourself with dynaplug. V easy, lots of folk on gtr.co.uk have used it with good results.

Costs about £30 too!

I think that "70%" is a general figure. The actual restriction on a repair will be the size of the "backing plate" on the plug that would be used. The plugs look like giant drawing pins, with a big wide head that gets "rubber welded" to the inside of the tyre. So the restriction will relate to centre of the hole being sufficiently far "in board" from the inside of the tyre wall such that the entire diameter of the head of the plug can lie flat. Nothing more scientific than that really.

Cheers everyone

I will let you know what a couple of places say after tomorrow

[shakindog]

where you take it for repair should have what is known as a puncture ruler which has a line down middle whichc you aline with center or tyre and will have markings to tell you dependant on tyre width if its a legal cold repair or not. if not as mentioned above find you local hot vulc repairer as will be cheaper than a new tyre

[CoolHands]

Tyre places will say no, I'm sure, even though IMO I'm sure it'd be fine. Get yourself a self-repair kit and do it, it'll be fine.
