Extreme Ti(y)re Puncture

Ok so the tube is the literal rubber of the whole wheelset? And the tire is just tube+rim…?

I feel really dumb right now.

geeeez, noob :smiley:

the tire is the outer peice of rubber that contacts the ground. Your tire is reuseable. The tube is the $3.00 tube that fits inside you tire and holds the air and keeps the bead of the tire locked into the rim.

Ok so, how do I change out the inner part of my reusable tire with a new, supposedly stupidly cheap tube?

I suggest you go to your local bike shop and ask them to teach you how to change the tube. Also, buy a few spare tubes and some tire levers from them so that you can fix flats in the future.

the first is a picture of an uninflated tube and the second is of a tyre …the tube goes inside the tyre and then the tyre goes onto the rim.


Aight well, I found this post by MikeFule, so I’m gonna head out to buy a set or two of tire irons and a new tube (maybe another just in case) and do it myself for cheaper. Do I look for a specific measurement (my tire is a 24x1.75 Kenda)?

Edit: Forgot to put in the link.

Sheldon Brown has a good web site on various bike repair topics, most of which are relevant to unis as well. This article will tell you everything you’d ever wanted to know about pneumatic bike/uni tires, and there’s a link to his article on how to fix a flat tire.

Flat tires happen; you should figure out how to fix them. It’s quite simple.

if your current tire is 1.75 then almost any 24" tube will fit…theres usually one thats just says 24" on it and it fits anthing from 1.75 up to 2.175.

Sweet…my set of bike tools already has one tire iron on it…and the deflated tire was easy to get off. I even found my hole.

I think I’ll just grab a patch kit tomorrow and fix 'er up, cause it’s just a very small, single hole.

Thanks for the help, guys. Now I know this stuff for the future! :slight_smile:

yeah changing tubes and tires will be a good skill to learn for riding…even more so muni which from your title line i can see that you are interested in.

I am suprised that you didnt already know how to fix a tube… But I am glad you now know and it willl be a very useful skill to practice (dont puncture a tYre for practice.

I agree with you that you should just patch it. It’s way cheaper and its easy to do, it isn’t a permanent salution but you will be getting your dx soon which once you get it, I doubt you will do much with your old uni.

Quick question: For buffing, does the seamline need to be completely gone if it’s on the patching area?

I’ve never taken it completely down and I’ve never had a patch fail. Some seams are pretty noticable and I take em down to where they’re just a small bump, then I put on the patch. Just be sure to press it down really well.

I don’t know if somebody else has said this or not 'cuz I just skimmed this thread, be sure you run your hand around the inside of the tire to make sure there’s no thorn or nail or staple or little piece of wire sticking through or you’ll just get another hole in your tube. Also, be real careful when you’re levering your tire back onto the rim that you don’t pinch the tube.

Good luck. This is an important yet basic skill any cyclist should know. And don’t feel bad if you make a mistake and have to do it a second time. We’ve all done it.

Yes, sounds like you never dealt with a flat tire on your bike before. But some of us just didn’t get to ride bikes when we were kids I guess. :frowning:

Cars don’t use innertubes any more, but they used to. Same for most motorcycles these days.

Hopefully you will read the Sheldon Brown stuff. I know it’s outside the world of Unicyclist.com, but you’ll notice he gets referred to an awful lot here. Unicycles are composed of a majority of bicycle parts.

Lastly, if you change out your tube, make sure to search the inside of your tire for any thorn or other protrusion that might be stuck in there. Feel around the inside of the tire (carefully) for anything that’s not smooth. If you forget this step, you may continue to get flats.

Nah, I never rode bikes that much before unicycling, really. Skating, rollerblading, and scooters were more my thing. But I’m glad I know how to know.

I did read a good amount of that link - lotsa helpful stuff.

And I did check my tire, inside and out, even with a flashlight just to be sure.

Just my 2 cents. It’s always better to replace the blown inner tube with a fresh one and keep the patched one in your backpack for emergencies. The patched tube is good but not as good as a new one. And buy a few tubes while you are buying them, I’ve found that 24" tubes are hard to find in my area.

Sounds like you are going to start muni-ing. If you plan on riding any significant distance from home, knowing how to change a flat is great knowledge to have, even for helping out the lady riders (oh yeah!). Keep a backpack stocked with tubes, an air pump, the right wrenches for your ride, and believe it or not, zip ties always come in handy. Just in case.

Cool tips, I’ll keep those in mind.

I actually think that once I finish patching up my CX, I’ll keep the patched tube in the tire, and only use that uni for freestylin’, and just not do any more muni or learning to hop or anything with it - I’ll save that abuse for my DX. :wink:

Bleeah! There’s no need.

Haven’t you ever repaired a tyre before? Try a tyre repair kit? About £3 anywhere. Why would you need a new unicycle?!


…new unicycle? I don’t recall saying that…that would just be dumb.
