Repair Patch Leaking

[artbuc]

Earlier this year repaired tire with combo patch/plug because damage was more of a slice than puncture. Did fine for a while but now has slow leak, maybe 1 psi every couple weeks. Tire has 8k mikes.

Can you redo those combo patch/plugs or should I buy new tire? Will get opinion from shop that did repair today. Thanks.

Buy a new tire.

I wouldn't attempt to "refix" it, because you might make it worse. 1 PSI every 2 weeks isn't a big deal. Especially if it doesn't involve a lot of high speed driving over long distances.

With only 8,000 miles that tire most likely isn't worn very badly. If your heart is set on a new tire, that's always an option. But if you took the tire off yourself, and took it to a tire joint, they could break it down and repair it from the inside.

That's most likely the best, and the most economically sound option that you have at this point.

If you mean the sticky string repair, then yes you can remove it and start over again. This is sometimes done when the first repair is not done properly.
If the puncture it not a hole but a slice, then it may have spread. In which case I would have the tyre removed and repair done from the inside with a mushroom patch

Since it's a slice, It is best to replace the tire.

It's also possible you've picked up another nail.

Patch close to the tire's shoulder ? They don't last long there due to tire flexing.

It was repaired from the inside.

It was in middle of tread. After talking with shop I bought a new tire.

Nope, I checked it carefully. It is leaking around repair.

Question for you. Using this case as a example. If you replace one tire with 8,000 miles of wear on the rear, could the difference in circumference cause undo wear on the limited slip differential at highway speeds over distance?

This is more a vehicle question than a tire question, so I don't know. But if I assume the tire is 20% worn (8,000/40,000), that's about 2/32nds and that level is within what sensitive AWD units are supposedly tolerant to, and I would think that would be OK for a limited slip differential.

1 psi in two weeks, to me, means, deal with it. Tires are expensive, and some leak down that much regardless.

I would have dealt with it, 1 PSI in a few weeks is nothing. Here in NY, once the temps drop near the end of the Fall season, I'm always filling up tires every 2-3 weeks. Never fails, new tires or old tires. End of spring and summer, tire pressure rarely goes down.

I manipulated the plug when I checked for air leak…nothing dramatic, just pushed back/forth with my finger looking for bubbles. Next morning it had dropped 10 psi. No way I am getting on interstate with that tire.

Buy a new tire. You can't re-repair a patch/plug especially if it's a long plug.

My car is FWD. Will keep new tire in rear.

[50yr Street Mech]

That's a different ballgame. If it dropped 10 PSI overnight, just because you wiggled the plug a bit, then the patch inside failed, and the plug was doing nothing. I would have gotten a new tire also. You had said it was a "slice" in the tire. Maybe the slice got a bit longer. Patches / plugs work well for small holes. Good move getting a new tire

 

[bonjo]

I consider 1PSI a week too much; a month is acceptable.
The mushroom plug repair from the inside is permanent repair and your was not done properly or you should've been told the tyre is not repairable.
Traction controls, ABS allow a certain difference in tyres rolling radii before activation. Tread wear differences would not be an issue.

That was the right call.
