Can You Patch The Sidewall Of A Tire? (Warning: Beware)

When you get a puncture, you have several options for repairs, one of which is using a patch to seal it up.

This is common knowledge for the tread, but is it something you can also do for the sidewall or shoulder? We’ve compiled everything you need to know about patching a tire sidewall.

Can You Patch The Sidewall Of A Tire?

You could patch the sidewall of a tire in some situations, but its effectiveness depends on the kind of damage you’re looking to fix. If the tire has suffered a puncture from something like a nail or screw, then patching should be an option. If the tire has been sliced and has developed a gash, then you should get rid of it and find a replacement as soon as you can.

You should also avoid patching the sidewall on run flat and self sealing tires because their enhancements are meant to help in the event of a puncture to the tread, not the sidewall.

If you get a puncture on your sidewall, you could patch it but this is not a recommended course of action.

Your sidewall holds in a lot of the tire pressure and supports a lot of the vehicle’s weight without the aid of a belt of cords like the tread, which is why any time it gets punctured you should just look for a replacement.

For this reason, in the U.S., the DOT has made it illegal to attempt repairs on the sidewall when the issue is a puncture.

Even on a run flat tire where the sidewall is reinforced, you should look into getting the tire replaced when it gets punctured because the reinforcements are only there to help you get to the shop.

It’s the same on self sealing tires when the sidewall gets punctured because the self sealing mechanism is only available on the tread.

You can’t patch too close to the sidewall and a good rule of thumb when patching a puncture on the tread is to make sure it’s at least 1 inch away from the tire shoulder.

In a nutshell, it is possible to patch a tire sidewall but we do not recommend it because a punctured sidewall presents a significant risk regardless of repairs.

Any patch work on the sidewall should be done in an emergency when you have no other options available, and it should be a placeholder until you get a replacement as soon as you can.
