What are the aftermath of placing a radial tube in a radial tire? Noticed today that I had a mesquite mandrel sticking in mine sidewall. Didn’t really look too big so traction it out and air followed!! Tires space relatively new with only about 13k mile on them. A neighborhood tire service (the huge one) desires $110 to change the 205/65R15 Kumho Solus KR21 tire. Bought these tires native Treadepot last year and also did no take the road hazard warranty. What are my options? thanks for any helpful ideas. John

I think the finest bet is simply to change the tire. A pipe (provided you can uncover anyone ready to mountain them, and also you wheels will accomodate them) is not virtually as sturdy as the proper tire. Due to the fact that your tires will have a feet in it, that presents a significant weak spot that can potentially fail further down the road.

A pipe is therefore old school it is downright dumb. Sidewall damages usually requires a new tire, that is a security issue, sidewall damages is the fatality knoll because that a tire.

I have to agree through FoDaddy. You’re much better off to replace the tire itself. A cheap solve will just put you and others at hazard of a blow out. If you carry out replace the one tires make sure you put the brand-new tire on the ago of the car, listed you have average wear top top the current tires.

A tiny pinprick native a thorn and the tire becomes structurally unsound! Wow! How fragile that tire is! whereby does this kind of reasoning come from?There are a pair of things you might do. You might put the thorn back in, and cut turn off the excess. You might use a tire sealant.Yes, ns know, you’ll hear, “Horrors, a tire sealant!” And, “The tire will certainly explode at 70 mph!” The declaration are founded on what? The many rational of thought? Or, room they, “I’ve always assumed…”

You deserve to use tube in tubeless tires. I carry out that on a motorcycle through spoked wheels. However, i would never do this with a tire through a damaged sidewall. There is just one solution for sidewall damage, and also that is to replace the tire.

I wouldn’t think a mequite mandrel would do too much damages to the sidewall yet the trick might be finding someone to execute anything about it.

Personally, ns think it would be fine through a patch and a tube. Numerous years earlier on a cross country motorcycle trip a rear tire blew on me during an embarassing and also emotionally painful escapade and also stuck between a rock and a difficult place, I had actually to download a 185 X 15" radial car tube in a 5.00 X 16" Harley Davidson motorcycle tire.In theory, this should have actually dumped me on mine head within 10 miles. In practice, that tube lugged me 900 miles home and also stayed in there for 2 an ext years through no problems. (clean forgot around it.)

(As an addendum, sprinkling talcum powder inside the tires can assist when a pipe is used. The talc stays clear of tube chaffing.)

Holes space stress concentrators - and since the sidewall undegoes a very facility motion - so complex patches often tend not to organize - the hole become the location where the crack will start. What you want to stop is the suddenly sidewall fail at high speed. Cracks will take a while to develop, however they at some point will fail the tire. Therefore it’s best to replace the tire.

If you want to know an ext about anxiety concentrators or crack propagation, Wikipedia go an OK job of explaining them.

Go to some ar that does heavy truck tires. Ask lock if they will do a “section repair” because that you. The is done every the time. Although a ar repair is still going to cost you around 40 bucks.

Too bad it was in the sidewall. They flex too much for a plug come hold. However for only a few bucks risk it’s precious trying one.

If it no work, replace the tire. Don not use Slime or and also other goo, together they’ll squirt out the valve when you adjust the pressure and also gum the up, and also they leave so much mess that numerous shops won’t work on wheels with that ingredient in them.

I doubt that anyone all over will not recommend against the use of a tube. It’ll change the tire’s handling and performance features to whereby it might be unsafe.

A tiny prick is a major stress allude which deserve to lead come catastrophic tires rupture!?Is that due to the fact that a rubber tires is so brittle?But, it’s ok to have actually a have a tiny nail puncture in the tread area, ream it out with a 1/4 customs reamer, and force a bigger plug right into it? Structurally, that big hole is benign for the tire due to the fact that it was make purposely with a tool?

Yes, I’m mindful that the ARA(?) American Rubber Association supporters tire plugs.

CapriRacer, I’d be glad to read your post on stress concentrators if friend would offer a much more specific referral than, “in Wikipedia”.

I would patch the within of the tire v a an easy tire spot kit and also then go with a tube. Follow OK’s advice and also shake in some talc powder . . . The constant rubbing of the tire versus the tube can create warm . . . And the talcum powder will certainly dial this down a bit. Offered to usage this procedure in dust track racing, never once had actually an concern with it. I can’t imagine exactly how a thorn would make a feet bigger than a nail hole. Keep an eye on it and also move on. Rocketman

Thanks everyone who replied to my question. Take it the tire down this morning to a smaller tire shop that had actually Kumho tires–Rick take it one watch at whereby the thorn went in and declared: patch that tire!! Evidently was no far enough down the sidewall come cause any type of problem. Drove away 15 minutes later on a happy guy. I highly recommend O’Malley’s tire Sales on the east side of san Antonio. Many thanks all again. John

Ah … fine … ah… i typed in the indigenous “stress concentration” in the Wikipedia search box and it took me right to the article. Ns did the same for “Crack Propagation” - and also that took me come “Fracture Mechanics”. I don’t understand what the problem is.

Here walk again. I simply wrote a prolonged explanation as to why you don’t patch sidewall however when i hit submit, I acquired a DNS lookup error and all is lost.

In the days of bias ply tires, you can patch the sidewall and get away with it. The is due to the fact that the toughness in the sidewall to be omnidirectional. In radial tires, many of the stamin is unidirectional. A tiny break in the sidewall weakens the currently weak longitudinal direction. Its prefer a timber board, that breaks much easier with the grain as opposed to versus it.

Since her thorn was close come the tread, the sidewall still benefited from the proximity that the belts. If the thorn had been more up the sidewall, the repair would certainly not hold and also the tire would fail. It would certainly be dangerous to drive but I think you lucked out this time.

I situation someone is reading this. The use of tube in motorcycle tires is accepted practice, however NOT passenger vehicle tires.

Since that tire is now over 11 years old, it has actually probably been changed by now.

Would be exciting if


The use of tube in motorcycle tires is embraced practice, but NOT passenger auto tires.

I’m pretty certain the Ford/Edison Museum in fort Myers is still using tubes in the tires as soon as they journey Edison’s design A and Model T Fords because that parade duty.

When a tube is provided a puncture usually results in a blowout when a tubeless tire normally deflates slow sufficient that the driver to reduce speed and avoids a catastrophe. And also a tube in a tubeless tire invites a blowout. A flap is necessary to safeguard the tube from chafing on the wheel and also talcum flour is needed to allow the tube to on slide onto a ideal fit and withstand regular flexing. And the tube have to be partly inflated climate deflated repeatedly. Pipe chafing is a far-reaching cause that blowouts top top tires utilizing tubes. That is a mistake to think that making use of a pipe in a tubeless tire results in a much more reliable, puncture proof tire.
