flat tire on bikes?

Question

im not such a fan at buying bicycles anymore because i have it for a week and then the tire pops. is there anything i could do or buy to prevent my tires from popping.and yes i am very careful not to ride on sharp objects.

Answer 1

I've been riding bikes for 26 plus years and having flats is part of riding a bicycle. You will have flats, it's inevitable.
I have looked through the postings and I agree with some, but most I don't.
Making sure your tires are inflated properly is a must. Inflation should be done before every ride.
The use thorn-proof tubes I don't agree with, all they do is add weight to the bike
Use tire sealant, and slime, I don't think so. Ask yourself a question, where does all this slime go if it doesn't seal? That's something I'll never put in bicycle tires. It's goop alright and it is not bullet proof and only works about 50% of the time and the other 50% you will have the biggest mess you have ever seen.
You can really have fun cleaning the inside of your rim and trying to get the stuff out of all the spoke nipples, say nothing about cleaning the tire after the stuff comes out of the tube YUK.
If you have a flat mark the location of the valve stem on the tire, remove the tube and inflat and find the puncture that will tell you the location of the puncture on the tire and you can remove the problem and install a new tube, it's a five minute job at best.
BTW bicylce tubes only cost $3.50 to $5.00

Answer 2

There are few things to do to keep away from flats:

1. Make sure your tires are inflated properly. Tires that are not inflated enough can "pinch flat" when hitting sharp bumps, edges, etc. Tires that are over-inflated can blow off the rim and pop as well.

2. Use thorn-proof tubes. They're much thicker / heavier, and less likely to flat.

3. Use tire liners. Slime makes some good ones. Just buy the right size for your tire (27" / 700c or 26" most likely), take off the tire and tube, and install the liner in the tire between it and the tube, and then re-install.

4. Use tire sealant. It's goop you put inside your tube to help it seal up punctures before your tube goes flat. You can even buy tubes with it already inside.

Answer 3

the first response pretty much covers it, but here are some more, the first few of which I have found to be repeat offenders.

You can check to make sure there isn't any glass (most tenacious) or other material embedded in the tire, or a sharp edge on the rim somewhere.

Make sure there is something protecting the tube from the spoke nipples... rim tape can be bought pretty much anywhere, or sports strapping tape works well as well.

Worn tires are also more susceptible to flats, especially worn slicks.

And finally, when 'seating' the tube and tire on the rim (installing) make sure the tube's lightly inflated (to mouth pressure works fine), so the tube can't pinch itself as you inflate it.

Answer 4

Firstly, check your tyre pressure. You can get things called pinch flats if your pressure is too low.

Next: I always ride with a spare inertube. That way, if you do ride over a big thorn, you should be OK. (Typical change times = 2.5 - 5 min(Don't forget the tyre irons)).

I also use Slime. It weighs a little bit, but will self repair small punctures.

If you go tubeless the self repairing stuff for this is very, very good.

Answer 5

I'm not really sure of the details of this,
but there's these kinds of tube that when popped
theres a gel inside the tube.
its called like a slimetube or something like that
and what happens is when the tire is punctured
this gel is forced into the hole by the wieght of the bike on top of it.
preventing most flats
very useful if you ask me
so useful that i havent getten a flat in over 3 years!
if this wasent helpful or didnt work, maybe look to see if the rim isent bent, causing the wheel to slowly move out of place and lose air very fast...making it look like a flat?
hope it helped!

Answer 6

Well, you can get a thicker innertube. A regular inner tube should cost about 8 to 10 dollars. A thick innertube costs from 16 to 20 dollars. I have the thicker one on my rear tire. they are really good. I prohop(jump) off curbs and stairs. I also do bunny hops, wheelies, and manuals on my bike. but yet, no air escapes and it doesnt pop. I just wish my front tire were more like my back tire. You can also buy a regular inner tube and buy slime which is 5 to 8 dollars. it comes in a bottle. thick inner tubes sometimes already have slime in them.

Answer 7

Make sure none of the spokes on the inside of the rim are poking through the rimstrips.
Get a roll of electrical tape and wrap it around the inside of the rim.
