What room the results of placing a radial tube in a radial tire? Noticed this day that I had a mesquite thorn sticking in mine sidewall. Didn’t yes, really look too big so traction it out and air followed!! Tires space relatively brand-new with only around 13k miles on them. A local tire organization (the huge one) desires $110 to replace the 205/65R15 Kumho Solus KR21 tire. Bought these tires native Treadepot critical year and did not take the road peril warranty. What are my options? thanks for any type of helpful ideas. John

I think the ideal bet is just to replace the tire. A tube (provided girlfriend can uncover anyone willing to mountain them, and also you wheels will accomodate them) is not practically as durable as the proper tire. Due to the fact that your tire will have a hole in it, the presents a severe weak spot that could potentially fail additional down the road.

You are watching: Can you put a tube in a radial tire

A pipe is so old institution it is downright dumb. Sidewall damage usually requires a brand-new tire, the is a safety and security issue, sidewall damage is the death knoll for a tire.

I have to agree with FoDaddy. You’re much better off to replace the tire itself. A cheap fix will simply put you and others at threat of a blow out. If you do replace the one tire make certain you put the brand-new tire ~ above the earlier of the car, detailed you have average wear on the existing tires.

A small pinprick indigenous a thorn and the tire becomes structurally unsound! Wow! How vulnerable that tire is! wherein does this kind of reasoning come from?There space a pair of points you could do. You can put the thorn back in, and cut off the excess. You could use a tire sealant.Yes, ns know, you will do it hear, “Horrors, a tire sealant!” And, “The tire will explode in ~ 70 mph!” The declaration are started on what? The many rational the thought? Or, space they, “I’ve always assumed…”

You deserve to use pipe in tubeless tires. I perform that ~ above a motorcycle with spoked wheels. However, i would never do this through a tire with a damaged sidewall. Over there is only one solution for sidewall damage, and also that is to replace the tire.

I wouldn’t think a mequite mandrel would do too much damage to the sidewall but the trick might be finding someone to do anything around it.

Personally, i think it would be fine v a patch and a tube. Numerous years earlier on a cross nation motorcycle pilgrimage a behind tire blew on me during an embarassing and also emotionally ache escapade and stuck in between a rock and a difficult place, I had actually to download a 185 X 15" radial vehicle tube in a 5.00 X 16" Harley Davidson motorcycle tire.In theory, this should have dumped me on mine head within 10 miles. In practice, that tube carried me 900 miles home and stayed in there because that 2 more years v no problems. (clean forgot around it.)

(As an addendum, sprinkling talcum powder inside the tire can help when a tube is used. The talc prevents tube chaffing.)

Holes space stress concentrators - and since the sidewall undegoes a very facility motion - so complex patches tend not to organize - the hole end up being the place where the crack will start. What you desire to stop is the suddenly sidewall failure at high speed. Cracks will certainly take a while come develop, however they ultimately will failure the tire. For this reason it’s finest to replace the tire.

If you desire to know much more about stress and anxiety concentrators or cracked propagation, Wikipedia walk an OK project of explaining them.

Go to some location that does heavy truck tires. Ask them if they will do a “section repair” for you. The is done all the time. Back a ar repair is tho going to cost you around 40 bucks.

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

If it no work, change the tire. Don not use Slime or and also other goo, as they’ll squirt the end the valve as soon as you readjust the pressure and also gum that up, and also they leave so much mess that several shops won’t work on wheels v that ingredient in them.

I doubt the anyone all over will no recommend versus the use of a tube. It’ll readjust the tire’s handling and performance qualities to where it might be unsafe.

A small prick is a major stress allude which have the right to lead to catastrophic tire rupture!?Is that due to the fact that a rubber tire is so brittle?But, that ok to have a have actually a little nail puncture in the tread area, ream it out v a 1/4 customs reamer, and force a bigger plug into it? Structurally, that huge hole is benign because that the tire since it was make deliberately with a tool?

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

CapriRacer, I’d it is in glad to check out your article on stress and anxiety concentrators if friend would provide a an ext specific reference than, “in Wikipedia”.

I would certainly patch the inside of the tire v a an easy tire job kit and then go v a tube. Follow OK’s advice and shake in some talc flour . . . The continuous rubbing the the tire versus the tube could create heat . . . And the talcum powder will dial this down a bit. Provided to usage this procedure in dirt track racing, never ever once had actually an worry with it. I can’t imagine just how a thorn would certainly make a feet bigger than a nail hole. Keep an eye ~ above it and also move on. Rocketman

Thanks everyone who responded to mine question. Take it the tire down this morning come a smaller tire shop that had Kumho tires–Rick take it one look at wherein the thorn went in and also declared: patch the tire!! Evidently was not far enough down the sidewall come cause any kind of problem. Drove away 15 minutes later a happy guy. I extremely recommend O’Malley’s tire Sales ~ above the eastern side of san Antonio. Thanks all again. John

Ah … well … ah… ns typed in the words “stress concentration” in the Wikipedia search box and also it take it me appropriate to the article. I did the same for “Crack Propagation” - and that took me to “Fracture Mechanics”. I don’t recognize what the difficulty is.

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

In the job of prejudice ply tires, you can patch the sidewall and get away v it. That is since the stamin in the sidewall to be omnidirectional. In radial tires, many of the toughness is unidirectional. A little break in the sidewall weakens the currently weak longitudinal direction. Its favor a timber board, that breaks easier with the grain as opposed to against it.

Since her thorn to be close to the tread, the sidewall still benefited from the proximity the the belts. If the thorn had been further up the sidewall, the repair would not hold and also the tire would fail. It would certainly be dangerous come drive yet I think girlfriend lucked the end this time.

I situation someone is reading this. The usage of tube in motorcycle tires is welcomed practice, but NOT passenger auto tires.

Since the tire is now over 11 year old, it has probably been replaced by now.

Would be amazing if


The usage of tubes in motorcycle tires is accepted practice, but NOT passenger vehicle tires.

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

When a pipe is provided a puncture usually results in a blowout when a tubeless tire typically deflates slow sufficient that the driver reduce speed and avoids a catastrophe. And also a pipe in a tubeless tires invites a blowout. A flap is needed to protect the pipe from chafing ~ above the wheel and also talcum flour is needed to permit the pipe to on slide onto a ideal fit and also withstand typical flexing. And the tube have to be partially inflated then deflated repeatedly. Tube chafing is a far-ranging cause of blowouts ~ above tires utilizing tubes. It is a mistake to think that utilizing a tube in a tubeless tire outcomes in a more reliable, puncture proof tire.
