How to change bike tires
7 signs to change bike tires
Tires are the most commonly used consumable when we ride regularly. Whether it’s long-term wear and tear, or being rolled to the curb by an idiot’s broken glass bottle, it needs to be checked and replaced frequently.
When you start clocking your weekly mileage, you’ll be amazed at how quickly your tires wear out or fail completely. Preempting catastrophic failures on long rides “from the back” can save a lot of frustration and walking. Read on for some tips when it comes to checking your tires and deciding when to replace them.

When you change tires, be sure to recycle old tires and tubes. Many stores offer tires as a free or cheap service when you buy them. This will keep them out of landfills and give new life to your old rubber for uses like playground rubber floors.
1. Worn tread
easy to spot. On an MTB or general-purpose tire, not having any tread remaining is a good indicator that it’s ready for replacement.
2. Flat point along the center of the tire
Road tires don’t have a noticeable tread pattern, but one way to notice wear is by creating a flat surface below the centerline and a square on the sidewall. Using tires on a stationary trainer can speed things up. Once this “ridge” occurs, you may notice that you get more punctures, it will be harder to maintain top speed, and cornering will become unpredictable. When a worn tire affects your bike’s performance, it’s time to replace it.
3. Cracked rubber on bicycle tires
The bike sat idle in the house for five years, really more. Rubber can become brittle with age and can be dangerous if not replaced. If cracks appear (they usually start in the sidewall), throw the tire away and get a new one.
4. Constant Units
On a road bike, a good indicator is a sudden increase in units. If you suddenly notice an increase in punctures, check your tires for wear, holes, and even make sure they’re seated correctly.
5. Cuts and Holes
There are all kinds of rubbish and debris everywhere on the roadside, especially after the rain. Even if you don’t get pierced right away, you’ll notice a constant accumulation of small nicks and cuts. It’s a good idea to check to see if any of these holes have punctured the casing, if so, you may need to replace the tire. Tubes inflated to 100 PSI will squeeze through any available holes, which often results in perforations.
Another important thing to watch out for is a sidewall cut or tear near the tire bead. This can lead to a puncture and any tire with a damaged casing (especially near the bead) should be discarded immediately.

6. Wear to the shell
As mentioned earlier, the lack of a discernible tread pattern on many road tires means that it can be difficult to determine wear. Once past the flat point mentioned above, you may wear down to the nylon thread (TPI), which strengthens and shapes the shell. If you see white fibers, throw away the tire and get a new one before you hurt yourself!
TIP: Many tires actually have “wear indicators.” This could be a groove or small dimple in the tread. Once this goes away, it’s time to get new tires. Some brands use different colors of rubber to indicate wear levels.
7. Bubbles or deformities
I went out for a bland ride on a sweltering summer day and didn’t realize something was wrong until the next day, when there were regular bumps 3 miles away… bumps… bumps. Upon inspection, the tire appears to have melted, thinned, and the inner tube is about to explode from the casing! When riding in extreme weather, check your tires for not-so-immediate catastrophic problems…something unseen may appear!
The reason why this type of tire is very popular among recreational riders and mountain bike riders is that it can meet the needs of traveling riders who want to avoid flat tires. The cyclist knows that if his tire bursts, he can quickly put on a folding bicycle wheel.
Foldable tires have higher threads per inch or TPI, which makes riding smoother and more comfortable.
I like this type of bicycle wheel to give me peace of mind when I go on off-road or off-road trips.
What makes folding bicycle tires compact
Foldable bicycle tire
It is well known that the wheels of folding bicycles can be folded into a compact and relatively flat shape. What makes this possible is that these tires have no wiring harness. Instead, they use bundled Kevlar cords to ensure the best flexibility.
What is Kevlar wire?
Kevlar is a tough and durable organic fiber. Unlike the steel wire used in ordinary tires, it is foldable. Due to this advancement in tire engineering, current folding tires are lighter and easier to transport than rigid equivalent tires.
Folding tires and ordinary tires
Now that you understand what a folding bicycle tire is, we will focus on the difference between folding bicycle tires and ordinary bicycle tires. This section is useful for people who cannot decide which type of bicycle to buy.
First, as described above, foldable tires use Kevlar fiber cords, which are easier to bend than steel cables used in ordinary tires.
Another difference between the two is weight. The TPI of ordinary tires is lower than that of foldable tires, and lower TPI means higher weight. Depending on the model, folding tires can save about 2 ounces per tire, so they are suitable for riders who want to pack lightly.
Third, the two types of prices are another factor that buyers should consider. Because foldable tires are more expensive than regular tires ($6 to 30 per piece), they are not very cost-effective, especially if one person has multiple bicycles.
Last but not least is the rubber composition. As a rider, I noticed that the softer rubber compound of the tire tread is often used in combination with foldable mountain bike tires. Softer treads have better grip on most surfaces, but they degrade faster than traditional tire treads.
In other words, it is still possible to find folding bicycle tires with sufficient service life. This model has two or three rubber mixtures instead of one.
In general, the choice between folding tires and ordinary tires is entirely up to personal preference. The light weight and easy storage of foldable tires may satisfy long-distance riders, but it may not matter for people who use bicycles only for short commutes.
How to fold folding bicycle tires
Suppose you get a folding bicycle tire, but you have trouble packing it. This section is useful to you. You can fold the tire in half twice, or fold it once and roll it into a ball. Then it should be compact enough for transportation.
When to replace folding bicycle tires
Folding bicycle tires
Since we already know that folding bicycle tires are not as durable as rigid bicycle tires, it is a good habit to look for signs of damage to avoid accidents and maintain optimal safety. Here are some common signs that your tires need to be replaced.
Cuts are the most significant sign. Therefore, if you find one of your tires, please replace it as soon as possible.
The second sign to look for is a bald tread. Take a moment to look at your wheels and see if the wear indicator is still visible. The excessively worn tire wear indicator has faded; to avoid accidents, if this is the case, I strongly recommend upgrading your bicycle tires.
Generally speaking, defects cannot be ignored. Always check your tires for faults or irregularities, whether they are caused by careless manufacturing or use. Most bicycle tires are folded when they are packed, and bending for a long time may cause difficulties. High temperatures can also weaken rubber tires.
