How to change and fix flat bike tire Trek Bicycle How to Fix Flat Bike Tire

the tire size is molded into the side wall of the tire. It will look something like: 26 x 2.125 or 700 x 35c
If the bike does not get a lot of use, you will notice after a few weeks that the tires are soft, this is because butyl rubber tire seep air, just like you car tires do over time. You may have picked up thorn or multiple thorns or glass and this could be imbedded in the tire. The tubes manufacturers spec on new bikes are notoriously thin and very prone to flats. Try replacing your tubes with Thorn Resistant tubes or tubes that have tire sealant in them like Slime Tubes (brand name). Remember to rub your fingers on the inside of the tire before installing a new tube to make sure you have removed the offending thorn, or else you are going to have another flat, sure as shootin'.

Take your tire to your local tire shop they can install a tube for you i would recomend doing both tires i had this done on my MTD snow thrower

Canadian Tire...you need a 12" bike tire tube. You should find them near the kids bikes.

Not a guru on Bertini but most strollers with pneumatic tires use standard tyres and tubes as used on kiddy bikes. I get tyres for Bugaboo's at my local K Mart. The size should be on the side wall of the tyre.

You need a set of tire levers to begin with.. anyplace that sells bike parts/tubes tires will have these.. they are just a nicely set of angled thin yet dull levers.

Using the levers you will need to lift one edge of the tire off the rim so the tire is half way on the wheel. To simply replace the tube.. continue on to B.

To completely remove the tire off the wheel.. flip the wheel over and using the levers pry the tire the rest of the way off the wheel. working your way around.. it will be snug then suddenly free.

Replaceing the tire is the same..except you only want to put it on half way before inserting the tube..


B. Remove the air stem cap and if you have the tool to remove the needle valve from the stem.. do that too as to let ALL the air out of the flat.. then pull the bad tube out.

Put the new deflated tube inside the wheel as flat and wrinkle free as possible starting with placing the air stem through the wheel.. and working it around until well seated.. some folks will use a bit of talcum powder on the tube.. usually they come dusted to allow them to properly fit when inflated.

Once you have the tube in the wheel.. start pressing the tire bead back under the rim.. depending on the wheel.. you may want to partly inflate the tube.. just a tiny bit.. so it will not get trapped between the tire and wheel rim when you re-seat the tire.. you can usually re-seat the tire to the rim with your fingers..becareful not to pinch yourself.

Inspect the wheel to make sure no parts of the inner tube is visible.. inflate to proper psi.. put on the stem cap.. replace the wheel.

You can buy a set of tire liners that will prevent punctures.. but of course this involves doing most of the above times four.

Lastly.. if you feel you just can't get it done.. stop by a good bike shop.. they will do it for you in just a few minutes.. possibly for no charge or little charge.

Best of luck!

I recommend replacing the inner tube, the size is on your tire. I think that you should pay to have it done at a repair shop if it has gears, it will be worth it in the long run

You need to either have a new inner tube put in it or you can try adding a flat repair gel in the tube to fix the leak. You can get what they call "Green Slime" their are other brands also available under different names but this is most common. It can be purchased at Walmart, Home Depot, Ace Hardware and Auto Parts Stores. This is easy to pump into the tube valve stem without removing the tube or wheel and should fix any holes or leaks on it. Then just pump it up and you should be ready to go.

True Goo inner tube sealant! Go to a bicycle repair shop with your stroller, and honestly, have all the tires shot up with this goo and then pumped up to your desired firmness...

I have a different jogging stroller, but I know the Maxi Cosi's Mura has the same air pump access as other bicycle tires like my jogger does. I kept getting flats, and this goo has kept my tires firm for 6 years now, I used to have to bring along a pump, but never again after this repair, it plugged up a small leak for one of my tires that kept going flat quickly and keeps the others from the eventual softness that was recurring.
