if my tire width is 2.1" then how wide should my bike tubes be?
20282
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.

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.

My tires are 26 X 2.125 (57-559). My bike is a 7 speed cruiser. I hope this helps.

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

you need to go to www.planetbike and look at their size chart. You can also call them and they will be glad to help. They go by size and tire width.

The tire I got was 20 x 1.75. (That is 20" diameter & 1.75 inches wide)It was an exact replacement for the one I needed. Most 20" bikes will use tires from 1.75" to 2.50" width. Hand brakes may need adjusting for width of tire.

Here is the long answer that should tell you everything you need to know about tubes and tires. First off, let's decode some of the numbers. 700C or 29" are both the rim size ISO 622 (that is 622mm in diameter where the bead of the tire seats on the rim). When you're looking at road tires, they're more likely to say 700C (from an old French system of naming tire/rim sizes) and when you're looking at mountain tires, they're more likely to say 29". Occasionally, some European tires, especially Continental, will try to confuse the matter by calling them 28" - but look fir the 622 to be sure of the size. 23/25 or 18-23 on a tube indicate a range of tire widths with which the tube is compatible. Since an 18mm wide tire has a much smaller cross section than a 25mm tire (just imagine those as the diameter of a circle), a tube designed to fit a 25mm tire can be much too big for an 18mm tire. In that case you'd risk getting the tube folded on iteself or pinched under the tire's bead - both of which can cause a flat. So, when selecting a tube, you should get the narrowest range that will fit. If you had a 23mm wide tire, 18/23 would be a better choice than 23/25, though both will be better than a 28/32, for example. The 48 or 42 mm length listed below is the length of the presta stem. Different manufacturers measure stems differently, so it's hard to get an accurate comparison, but a 32 will be shorter than a 42 will be shorter than a 60 and so on. You just need 12-15mm of stem to stick beyond the rim so you can get a pump onto it, though, for some people, a little extra length isn't a bother. If you've got a deep rim, you'll need a longer valve stem. But if the 48mm stick through with plenty of extra, a 42 is a safe choice. ORDER ROAD RACE TUBE. Thus is your present tire is a 25, I would get the 20-25 tube, less chance of the tube folding over or pinching it because it is too big. Hope all of this information is useful in the future.

I cant answer for sure because my son's bike has 1.5 inch tires. However it appears to be big enough to go around 2.25 tires if you have a cable release it will help on install. Otherwise you may have to release the cable to get the caliper around the tire.

The measurement between the wheel loop is 3 1/2". 4" tires sound extremely wide. Most average mountain bike style tires are about 2-3". Did you physically measure your tires? Maybe you could let some air out and they would fit if they are that big. I'm very happy with the rack. Good luck!!

My tires are 26 X 2.1. They are working fine. I had not trusted the rubber ties that came with the fenders so I placed enough plastic ties on the to hold them in place and they haven't come off. My bike has disc brakes front and rear. I had to take the fender holder on the front forks off because it would cause the tire to rub the fender. I hope this helps.

As long as the rim is 26", they should work. I have them on a rim size 26" x 1.5" and they work fine. I'm sure they would work on a rim with 2.1" wide tires as well.

I run 2.3 x 29 's on my bike and one cartridge is enough for a tubless fill so more than enough for a 1.95 tire

1.5 inches... if your putting bigger tires on I wouldn't go bigger than 32's

you need tires that are 26x2.125 if you have a 26 inch bike.most tubes will say on box.26x 1.75 to 2.125 put a little air in tube,then put in tire to,install easy..if its late 50s could be 26x1.75 make sure of 26-25 size wheel make sure of your size put wheel next to other size wheel on a other bike keep riding!!

You don't want to put more liner in than you need. 29 inches of liner in a 26 inch tire. Nor do you want too skinny liner if your tires are fat, or too wide liner if your tires are skinny. Your tire should have a size written on the side. Get liners that have a range that includes your tire size. 700 is a road biking tire size. it is however identical in diameter to a 29 inch tire...622mm in diameter. the 700 are generally more narrow for skinny road biking rims. You probably want blue for very skinny 26 inch tires, Silver is for "regular" or "normal" width 26 inch tires, and brown is for the wider 26 inch tires.

It should. I have 26er with 2.1" tires and there is plenty of width left. Only issue I had was disc breaks not fitting well (had to modify the unit).

I am not for sure, never heard of 1.92, a 2.25 is a big balloon tire, next is 1.75, medium size, then like 1.38 schwinn s/6, for cruiser's all, need to check fender allowance
