if my tire width is 2.1" then how wide should my bike tubes be?

Each tube has a minimum/maximum tire size. click select to see the different options. a 2.1 tire would be just under the max width of 2.2 which means the tube will expand almost fully before filling the cavity

Most tubes give a min max tire size. A 2.0 to a 2.25 would work fine for a 2.1 tire.

The tube should list the size range that it supports. The range should cover the size of your tire. So Presta, 26" X 1.75"/2.2" would fit 26" tires from 1.75 to 2.2 and would fit your tire. I love my Serfas tubes. They seem to hold air better than most, therefore I don't have to pump them up as often.

Not sure what size bike you have or tire you need. If your bike uses 26" tires them yes this is a great tire.

The inside diameter of the loop is 3 1/2 inches that your tire sit into. Most bicycle tires have a crown I think the crown should recess down inside the loop your tire should be just fine if not you can probably spread the loop a half an inch and get it to fit better.

These fit only small diameter tubes as on a standard bike rack. I'd say they are about 1/4 inch.

Make sure it is a 26x2.1 you are trying to fit. A 26" tire will fit any 26" rim but you have to watch the width. A 1.75 will not fit a 2.1 so make sure you have the right width tire. Match with the numbers on the tire you are trying to replace, they will be on the side of the old tire.

I purchased new tires for my wife's Schwinn Beach Cruiser but they were the 26" x 2.125 and they were a perfect fit for the wide rims. I would also suggest getting new tubes.

The main dimension is the 20", and will only fit a 20" rim. The second dimension 1.75"-2.125" is the width of the tire, some bikes have thinner rims (1.75" tires) and some bikes have wider rims (2.125" tires). This tire will fit both. In my opinion this tire is on the thin side.

Just Curious- If you want a tube for a 26x2.35 tire you need a tube that is 26x(range includes 2.35). Amazon's search engine will send you on a wild goose chase if you let it. This tube is not right for your tire. Jim

Sorry I don't know the answer. tube size, I have several different bikes, I use is marked on the side of the tire. I am guessing by information that you should check for marking on tire itself. The 27 x 1 1/4 fits only one of my bikes and I fill them to about 100psi.

I tried using the 26"x2.1" tubes on these tires to try to save money. I think the tube was too big cause the tire blew up. You need the right tube. I ended up getting 26"x1.5" tubes and it worked great. I did the Trans America three years ago on these tires, and only had one flat. I still have these tires. They wear very well.

I am running 2.3" Geax Tattoo tires with plenty of room. I dont know the max width you can run. They are very nice forks. Light and stiff with a remote lockout for 200. Can't go wrong.

Look at the tire size that you will be putting it into. Buy a tube to fit the tire.Jim

There is usually a range of tubes that will work. Sunlite Bicycle Tube 26 x 1.95 - 2.125 from Amazon will do fine. 26" is the rim diameter and the other is the tire width. You also need to determine which valve you need. Schrader or Presta. Presta is the smaller one.The Schrader is the larger one.

This tube will fit 8" - 8-1/2" outside diameter tire, 2-1/2" wide on a 4" wheel.

More than likely. The second number in the tire/tube size is the tire width. I can't see how one inch width would make a big difference.
