If you've ever looked at a bike tire before, you probably know that it comes in two parts -
the inner tube and the outer rubber tread.
Most problems happen with the inner tube, and these are fairly easy to repair. There are some cases though, where the tube may need to be replaced.
A good puncture repair kit will patch up most holes that are small in diameter. Obviously if the hole is larger than the patch, it's a bit more difficult. A common one is with a blowout. This is when a large section of the inner tube (usually along the seam) bursts suddenly after an impact. You will know if this is the case at the time of the damage as you will hear a small explosion from your wheel.
Another reason to replace your tube is if you have several punctures. (Did your angry neighbour throw down a bunch of wall tacks again?) Not only will most repair kits only provide for one or two holes, but these multiple breakages will weaken your tire for when you next ride.
Similarly, if your tube already has several patches, or is simply a few years old, it may be time to get a new one. Aged tires usually hold less well against further damage, even if you do a proper repair job. Check both wheels every few years, regardless of whether you've had any punctures. The tube should look smooth, tight and spring back when you pull on it. If it appears worn, you need to replace it.
These are all reasons to replace a damaged inner tube, but what about the outer tire? Outer tires are more resilient to damage, but they are also a lot harder to fix. If you suspect a problem - such as a large tear in the tread - it's a good idea to replace the tire straight away. Outer tires can be more expensive, but ignoring it could risk injury to yourself. Replacing them is well worth it, and you can still keep the same inner tube.
Luckily for us, most damages don't require you to replace a bike tire - but it's good to know what to look for and to be diligent if a replacement is required.
