Bike tyre sizing is a horrible mess. Your wheel is a 700c - that means the diameter of the whole wheel. you have to get a tube that is a 700. The second number on the tube relates to the width of the tyre, and is often given as a range. Racing tyres are 18-23 mm, the next band is often 25-35, So you need to read the writing on the sidewall of your ...

You need to know what caused the flat first (recommended reading here); it may merit replacing the tire itself depending on cause. The tube will be 700c x a-b where your tire size is between a and b. The rim strip needs to be matched to the rim width. See this question to measure it. Depending on why the rim tape snapped, you may need to make some ...

I'm going out on a limb and suspect you have removed the end nut and have pushed the valve core down into the tube to allow the sealant liquid room to move past and into the tube ? Short answer is, don't do that. Use tubes that have a removable valve core. These can be identified by two flats on opposite sides. Since you've probably already got the ...

If you purely have a puncture by a pin, small nail, or fragment of glass, and the hole in the tire is just a puncture and not a slit, then there is no need to do anything special with the tire -- just put in a fresh (new or repaired) tube and go. You do need to be concerned if the puncture somehow causes a cut in the tire, with a dimension of more than ...

The size of the puncture really dictates whether a new tire is in order... that being said, if you patch your tube and inflate the tire (the one with the puncture) you want to make sure the tube is not exposed through the puncture hole. If you need to ride and the tyre is questionable... an old trick is to put a dollar bill or power bar wrapper on the ...

I would check your tire for tiny tears along the sidewall. I had a problem with my tubes leaking as well until I figured out that the tube was expanding into the tear of the sidewall and getting pinch flatted. Although, a slow leak is a little strange. If you don't see any tears in your tube, try replacing your rim strip, since it does seem to be acting ...

Check inside of tire for a prick with finger. Do the same for rim liner and rim. It could be a metal shaving or glass.

There are two ways for air to leave a tube - an actual slow leak in the rubber or a faulty valve. Since you've checked the tube and changed it. this could be a technique thing where you're pinching the tube creating a small hole that is not big enough to show up in a water test. Try inflating your naked tube to a pressure of about 10 PSI. It will double ...

What can you afford? If you're not really struggling financially you should replace the tire. If you cannot afford that (or if you need a temporary fix while you're obtaining a new tire) then you need a "boot" inside the tire. A "boot" is some piece of flat material (typically about 5 cm x 5 cm, though size can vary based on tire size) that is flexible ...

No harm in trying to get some more life out of it. You'll need to patch the tube normally, and test it overnight. Then you need to provide something to stop the tube bulging out through the tyre when inflated. Personally I'd put the largest thickest patch you have on the inside of the tyre, but others would use a piece of plastic or something else ...

Presta valves are fairly fragile things. It's easy to bend the stem once it's unscrewed. They work by the tube pressure being higher than the atmospheric pressure. This causes the valve to be forced closed. It is not until you either loosen (unscrew) the valve and depress the stem or place a pump on it and increase the pressure above the valve until it is ...

When I deflate the tube, often a bit of slime comes out as well at the end, and you can see the residue at the valve. Most brands seem to be very bright colour (green or orange) so it is very noticeable. Also when I inspect the (inflated) tyre for cuts and damages (good idea to do that every week or so), I can sometimes see green goo where I had a small ...

take the wheel off, put is verticaly and spin it. A tire with slime rotates "differently". You may feel the slime circulating in the tire.
