Is this car tire repair too close to the sidewall or not?

May 19, 2018 19 Replies

Just repaired this tire and was wondering since it seems borderline.

What do you think about the sidewall proximity?

I plugged it with a string tie from the outside.

After cutting both sides flush, I patched it from the inside.

I accidentally got the rubber cement on the patch, but it seems to hold.

The main question is whether the hole is too close to the sidewall.


  As long as it's in the tread belt you should be OK .

Looked OK to me to. Not sure tire would pass the Lincoln penny head test though - looks pretty worn.

You're fine with that repair, but the tread looks worn down beyond safe depth- unless of course you never drive a a wet road. Time for new tires!

That would be my concern too. I'd be out tire shopping this week.

Most certified repair facilities will not plug/patch a tire within 1" from sidewall edge as they say "liability issues", but I believe they mean "potential sale".

I've done several repairs even closer and they've held up to the life of the tire. Your repair looks fine but as others have said, treadwear doesn't look well. Be careful in wet weather.

It's not down to the replacement wear indicator that you can see in the pho to. Exactly how much is left, hard to say because it's a vertical shot. They would definitely pass the penny test on the section we can see, I'm guessing there is about 4/32 left. The Lincoln test is 2/32, which is the wear indicator.

According to the tire repair association rules the tire is technically "unrepairable" but I've seen MANY successfull repairs in that portion of a tire and have repaired many my self.

Keep an eye on the tire, but I wouldn't lose a lot of sleep over it.

The tread wear indicator bars are still below the tread level - so it should pass the "penny test" - but the tire IS getting worn.

Depending on the usage, it could well last another season, but wet traction will be compromised somewhat. I'd be more worried about the AGE - and hardening of the rubber. Check the sidewall date code. If over 6 years old, go shopping.

Borderline!!!!???? It's d'd near the middle of the tread.

The tire's done wore'd out, but other than that...

What does d'd mean? The plug sure isn't near the middle of the tread. I think it's still OK, I'd plug it there, but it's not in the middle.

Insert your preferred middle :)

OK, I only looked at one of the pitchures; in it thought looked like the center tread bar rather than the outer. It's still well down into the tread away from the sidewall, however, as far as the patch location; it's still an already wore out tire, though. :)

I think my earlier pictures must have been really bad

because the tire has, I think, plenty of tread,

as you noticed,

where the tread is nowhere near the wear bars

unless I'm missing something.

I'm more worried about two things that could signify "danger".

  1. I put glue on the patch after peeling off the blue plastic, where I think I wasn't supposed to do that (the patch seems to be holding though).
  2. I'm mostly asking about how close is too close to the shoulder.

This graphic shows it is clearly too far over the edge of the safe area.

But this graphic shows it is right on the edge of the safe area.

The problem is that there isn't any consistency to that advice. Which is why I ask you and provided the pictures.

What do you think about the proximity to the shoulder on that repair?

Though not directed to me, I'll answer,

Agreed. Must have been bad angles and/or lighting. Tread looks very good.

As I stated in my reply below, Too close is within the 1" from the edge. You provided a link with the description, why are you then asking?

As others have said and agreed, your repair looks good. I think you're worrying too much about it. If it's holding air, burn rubber, drag race it, do stunts on two wheels, the tire will be fine.

I'm directing the question to everyone who can help me.

The first set were taken indoors last night. The second set were taken outdoors in the trunk of the car.

For some reason, indoor lighting universally makes tread disappear! :) Outdoor lighting brings it all back! :)

Did you look at both sets of links? Some show 1/2 inch. Others 1 inch. One looked about 1.5 to 2 inches.

I would have driven it to Goodyear who patches tires free but I needed the car today so I didn't have time to set up an appointment.

Plus I wasn't sure if they'd patch it since there seems to be a HUGE leeway in what is considered too close to the sidewall by the looks of the conflicting articles.

It's my first patch so I didn't know you're not supposed to but the rubber cement on the patch itself after peeling away the blue plastic.

I'm leaving for a long trip so I wanted the patch to hold. I have a spare but it's a different tire brand.

Looks OK. We could only judge by your first pictures.

d'AMNEd near.

Clears things up for ya?

Like I said - officially it's on the edge -according to the tire industry association. It is beyond the outermost tread cut - in otherwords "outside the tread area". That said, I would still repair it.

If it is a "speed rated" tire the repair would negate the speed rating

- in my opinion - but it is still a useable highway tire at legal highway speeds. The tread is definitely well within range.

He needs to go buy a used replacement tire with no plug or a new set of tires. I can already tell that's the only way his mind will be at ease.
