10 best self seal inner tubes

Sure thing! Self-sealing inner tubes are a nifty invention for cyclists.They come equipped with a sealant inside the tube that automatically plugs small punctures, preventing air leaks. The sealant is usually a liquid latex that forms a protective layer over the puncture, keeping your tire inflated for a longer period.

These tubes are particularly handy for riders who want to minimize the hassle of dealing with flat tires during their cycling adventures. The self-sealing feature doesn't make you immune to all punctures, especially large ones, but it's great for those pesky little thorns or sharp objects that can ruin a good ride.

Just keep in mind that while self-sealing tubes offer convenience, it's always a good idea to carry a backup tube and the necessary tools in case you encounter a more significant issue on the road. Happy cycling!

Tube Size

First and foremost, you want to make sure the tube fits your tire. To determine the size you need to check the side wall markings on your tire where you’ll see two numbers separated by an 'X'. The first number refers to the tire’s diameter. The second number refers to the tires width. Select the tube that has the exact same diameter as your tire. Your tires width should fall into the range of widths listed on the tube packaging.

Valve Type

Standard (also called Schrader) valves are the most common valve type for bicycles. This short, sturdy valve is also used on car tires and other inflatables.

Presta valves are typically found on performance road and mountain bikes. They have built-in valve locks which you twist to open before inflating.

An easy way to remember is: 'S' is for Standard (Schrader, Short, Sturdy) and 'P' is for Presta (Performance, Premium).

All inflatable tubes are subject to deflation from mis-installation and certain hazards.

Flat Protection

Finally you’ll need to choose whether to go with a standard or self sealing tube. Standard tubes are fine for most riding conditions. Self sealing tubes have liquid sealant inside that provides an extra layer of flat protection by sealing holes up to 1/8 of an inch instantly while you ride. It doesn’t get much easier than that!

Question: for a 26"? Is this a 2 pack

Question: in the event you do get a puncture, do you just patch a slime tube up like you would a regular tube? (never used a slime filled tube before
