How to Change a Flat Bicycle Tire

1) Begin by looking at your old bicycle tire, and find the dimesions of the tire on its side. Write down these dimesions, becuase you must then go buy a new innertube for the tire that is the same (or about the same) size. I suggest going to a bicycle store; at the one near me tires run about 5-10 dollars.

2) With this new innertube in hand, you can begin changing your bike tire. You must start by taking off the entire bike wheel. To do this you need a hexagonal-shaped wrench thingy that looks like this:


See the hexagonal wrenches on the left side? You're ging to need something like that to remove the wheel. If you don't already have one, you can get this one from here (Walmart.com), or you can look up 'bike tool' on Amazon or Ebay.

3) You then use this tool to remove two hexagonal bolts, one on either side of the wheel; shown here:


Then use a flathead screwdriver or another falt object/tool to pop the outer tire off to expose the old innertube inside, like this:


4) Remove this old innertub, and put the new one around the wheel. It might seem a little big, but that's okay. Proceed by slipping the outer tire back on over the new innertube, using the same tool you got it off with.

5) Put the wheel back on the bike, screw the bolts back in, and inflate the tire to whatever PSI (Pounds per Square Inch) it says on the side of the tire.

6) You're bike is ready to ride again!

here what you want ? An why you are doing this? how are you any way a


First, I would suggest going back to third grade and learning how to spell. Then look at the side of your tire for the size. It will be a set of numbers such as 26 x 1.75 or 700 x 40 c. Go to Walmart, buy the same size tube for your bike, take old one out and put new one on.

bike rim change 26x1.95 to 27x1.25 on Mountain bicycle


If you're saying you want to keep your old hubs and install roadie-sized rims so you can use road-friendly and efficient tires you're looking at an expensive and wasteful project. The hubs would be the only parts that are potentially re-usable. I seriously doubt the rims you have right now are 1.95" wide. I have several mountain bikes and many wheelsets and not a single one that I can't put anything from 26x2.25 to 26x1.10" tires on. At 100-plus psi the little tires are hard as rocks and roll nice.

If you DON'T have disc the whole project is a non-starter becuase you can't arbitrarily change wheel sizes on a rim-brake-equipped bike. Disc brakes would require you to have disc-specific hubs so search the web for "700c disc wheelset" that match your disc size (if you have disc).

If you want to DIY you'll need some special tools and skills.

Then you'll have to select rims and find an online spoke length calculator so you can order the precise lengths you'll need, assuming you have data for your rims and your hubs.

Look online or eBay, too.

A Bike Shop might be willing to lace on new rims and spokes to your hubs but it will be expensive and you would be destroying presumably fucntional MTB wheels. By the time it's all ordered and installed it would probably have been cheaper and more reliable to have just purchased new wheels.

Can you buy spare tires for an old baby jogger performance, the tires are 16


I'm sure you can, but some more details would be necessary. Look at the sidewalls. There should be a set of numbers molded int othe rubber that goes something like "# x ?.??". Copy it down verbatim and look for that same spec. A real Bicycle Shop would be glad to assist you in identifying and obtaining what you need.

Or look on eBay.

I just needed to know what the recommended air pressure is for an avalon 7 speed men's bike from Walmart?


Look at your tire,on the side wall it will tell you what amount to put in. Do not fill at a gas station, it is made for a car tire, and will blow the tire off the rim. Buy a tire gauge and a decent pump, and watch the bead on the tire to seat evenly as you add air.
