Bike tires are the only grip your bike has with the ground. There will come a time when replacing them becomes inevitable.
Replacing a bike tire could arise after you passed a certain mileage threshold or by damage appearing on your tires. The most common sign that your bike tires should be replaced is a sudden streak of flat tires.
What kind of tire does my bike have
All tires have the dimensions written on the side. The bigger number is the diameter of the tire, from numbers ranging between 26″-29″. The other number being the width of the tire ranging between 13-27 mm is the width of the tire
Do bike tires differ for different bike type
Yes, bike tires differ. Even for different seasons, you could have different tires. But fear not, buying the same diameter and width will limit your choice and you can go from there. On the subject of tire width, now could be an opportunity to test some narrower or wider tires. Your wheel could handle some 1 or 2 mm wiggle room. The general area left to look for when buying new tires is at the thread pattern. You can find this information when you choose for the right activity you’re doing. As an example, touring and downhill will have different patterns. These need different grips in specific situations. As for the seasonality aspect, MTB tires made for the winter are much wider than normal ones.
How to spot a damaged bike tire
A tire can be damaged in several ways so be sure to check every case.
For an MTB:
- Worn out center pattern. The side pattern and the center pattern are different in style and height. This is for good reason as they’re used for different cases. The side ones are for cornering. Even if your side pattern looks good, you may need to replace the tire.
- Seeing the threads. If you see threads, that’s a bad sign. That means that the protective rubber is now gone and debris will damage your tire even further. Not to mention that you now have no grip in that area.
- Cuts around the tire. This can be especially seen around the side. These may appear when riding with low-pressure tires or poor storage conditions. Like having the wheel with no air completely the tire has the whole bike weight on it further damaging it.
- Inconsistencies. Check if some pattern threads are cut off. If there are several, it’s a good time to change the tire.
For a road bike:
It’s trickier for a road bike to check for damaged tires since there are not patterns that can be worn out. It’s also more dangerous to have damaged tires since it’s a guaranteed falling.
- Wheel symmetry. Rotate your wheel in the air and look if the wheel is slanted in one direction.
- Puncture streak. Having a streak of punctures will raise the question of whether the tire is damaged. And that is letting debris in and damages the tube.
For both types of tire:
- Check for a bulge. A tumor-looking bulge is something to worry about and needs replacing.
- Wear indicator. Some tires have a wear indicator for you to easier know when a tire to be replaced.
- Sidewall cracks. Storing a bike wheel with no air will damage the tire on the sidewall and create cracks. Always leave your wheels with some air in them in storage.
- Check both wheels. You may have doubts about one, but while you’re at it check the other one too.
You can also check your manufacturer’s website for specific tips about bike tire wear.
Even though your tires do not show any sign of wear or damage, that’s not enough. Tires need replacing after a certain mileage has passed.
