OK to Use a tire patch for leak that was repaired but has slow leak

[Captn Conch]

I had a very slow leak that had a rectangular about 1/8 x 1/4" little piece of metal down in between tire lug tread. installer used the tire plug but has very slow leak. they said can't fix it. the tires have little wear but a new tire of that brand is not being made anymore. Could a rubber oval inner tire patch that is glued in and a tube do the job? I don't want a new set of tires. If this is not possible. I am going to put on 2 new tires of the same type with somewhat similar lugs. Current tires are Dick Cepek Extreme Country 33x10.5 r15 new tires are Mickey Thompson Baja Legend MTZ. would put on same axle of course. Is that a problem as there my be a little difference in diameter d/t some tread wear etc...

Depends on the hole… I pin hole could be successful… yours sounds more of a tear …. So not really … there’s not much meat there and the sidewall flexes to much … making the spot susceptible to separating later

You don’t have a matching spare?

I would, I have also used a second plug with long term success!

Slow leak - clean area as best you can with a good solvent mek, acetone, break clean both inside and the outside. Paint with several coats of patch adhesive - you could try to work the glue in with an old syringe on the first go.

Sidewalls don't patch well - especially for highway speed or extreme off road.

There were patches made like mushrooms that were installed from the inside - the stem was pulled threw the hole from the inside the cap did the sealing. Then there were the heat vulcanizing ones that were clamp in place and set on fire. Big metal cup about 1/4 inch deep full of some sort of burning compound with the rubber patch on the other side of the cup.

I fixed a buddies 4 wheeler tire with like 14 plugs in the hole - they lasted years until the tire wore out and never leaked. Buy extra plugs and a big can of glue - those little tubes dry out after the first use.
