What Is A Foldable Bike Tire?

A folding bike tire is exactly what it sounds like – a tire you can fold down, so it is compact enough to carry around in a bag. This type of tire is ideal if your mountain biking discipline requires long travels and high-quality gear. For instance, if you are into cross-country mountain biking, having a folding bike tire is ideal so you can quickly get back on track if one of your tires pops.

Folding bike tires feature a high thread per square inch (TPI). For this reason, it makes rides smooth and comfortable. These tires do not weigh much and take up a lot of space, making them convenient to carry around.

In addition, foldable bike tires are an excellent option if you want to stock up on an extra tire or two but need more storage space. You can simply fold the tire twice and roll it into a ball. This way, it will fit into the pockets of your bag or in the drawers if you are storing it at home. (source)


Learning about Mountain Bike Tires could take years. Let me help you just a bit quicker with some articles.


What Makes A Folding Bike Tire Foldable?

You can fold and flatten a foldable tire because it does not have the wire bundles commonly found in regular tires. Instead of wires, they use Kevlar strands bundles, making them highly flexible and durable.

Kevlar strands are durable organic fibers developed by combining phenylenediamine and terephthaloyl. They commonly find use in protective clothing, such as bulletproof vests. Although flexible, Kevlar strands are more robust than steel, so even aircraft have parts made of organic fibers.

Moreover, Kevlar strands are ideal for bike tires due to their resistance to:

  • abrasion
  • high temperatures
  • acids and bases
  • stretching (source)

Differences Between Regular And Foldable Tires

Choosing and installing the wrong bike tires can ruin the quality of your ride. While a high-quality tire can make your ride smooth and comfortable, a tire that does not fit your riding style’s demands can make your adventures less enjoyable. So, before switching your regular tire to the foldable variety, it is crucial first to understand their differences.

The Material Used

As mentioned, the bundles of steel wire called beads are present in regular bike tires but not in foldable ones. These fabric-covered wire bundles run throughout the circumference of a standard tire. They are responsible for locking the tire onto the rim and making it strong since rubber only has little strength.

On the other hand, a folding bike tire has Kevlar strands instead of beads. While a foldable tire is just as durable as the regular one, the Kevlar strands give it more advantages, such as the flexibility needed to fold it down.

TPI Count

Regular bike tires have a low thread per square inch or TPI count. TPI refers to the density of rubber or nylon for every inch of the tire.

Since regular bike tires have low TPI, their threads are large, making them sluggish and heavy. However, these large threads are also beneficial as they make standard tires highly durable, causing them to have a long lifespan.

A regular tire with low TPI is ideal for cyclists who want high mileage.

Meanwhile, folding bike tires feature a much higher TPI count than regular bike tires. Apart from the Kevlar strands, the high TPI counts make foldable bike tires flexible. It also helps the tire conform to the trail surface, especially when passing through corners.

Folding bike tires have high TPI, making them ideal for cyclists who want their bike tires to have more traction against the ground.

Moreover, the higher the TPI of folding bike tires make them lighter than regular tires. The reason is that higher TPI uses tiny threads, which are significantly lighter than the large threads used in tires with low TPI.

Flexibility

As mentioned, the Kevlar strands used in folding bike tires improve their flexibility. These organic fibers also make the tires foldable and easy to pack.

Extreme flexibility is a characteristic that regular bike tires do not have. Since this type of tire consists of steel wire bundles, it is impossible to fold and roll it down into a compact. So, switching to foldable bike tires is ideal if you are into long-distance cycling and want to bring a spare tire during your trip.

Rubber Material

Regular bike tires feature a durable, rigid rubber material that does not quickly wear out. This rubber compound accounts for the tires’ durability and high mileage.

On the other hand, the rubber compound that makes up foldable bike tires is softer. Apart from the Kevlar strands, this soft rubber compound also makes folding tires flexible. It also improves the tire’s traction when passing through corners.

However, the soft rubber makes foldable bike tires wear out faster than regular tires.

Fortunately, bike tire engineers were able to come up with a way to make folding bike tires wear out slower. They utilized a dual–compound tread, which reduces the tires’ rolling resistance, thus preventing it from wearing out fast.

If you need your bike tires to last long, go for regular tires. If you want better traction and convenience, folding bike tires are ideal. (source)

Advantages Of Folding Bike Tires

While a folding bike tire’s soft and flexible body causes it to wear out faster, it still boasts advantages that you cannot find on regular tires.

Lightweight

The steel wire bundles present in regular bike tires not only make them unfoldable but also make the tires heavy. On the other hand, Kevlar strands are lightweight, making folding bike tires lighter than regular tires. This benefit allows you to bring an extra tire during the ride.

The lightness of foldable tires makes them ideal for long-distance cyclists and those who want to reduce the overall weight of their bikes.

Durable

Kevlar strands are abrasion-resistant. For this reason, the sharp objects, like rocks scattered throughout the trail, will not penetrate folding bike tires easily. This factor reduces the chances of your bike tire blowing out as you pedal.

Apart from abrasion resistance, extreme heat does not affect Kevlar strands. So, you can go on an adventure on a hot sunny day without worrying that the heat may damage your folding bike tires.

Smoother And More Comfortable Riding Experience

Since foldable tires make your bike lighter, they also improve your riding experience. Bike tires need to be as light as possible so that cyclists only need to exert minimal pedaling power. The lighter your tires are, the less tiring it will be to keep them moving.

Use folding bike tires if you want your adventures to be smoother, more comfortable, and more enjoyable.

Listing The Disadvantages

It is undeniable that folding bike tires are advantageous. But just like any other bike equipment, they also have some disadvantages that you should consider.

Price

Folding bike tires are more expensive than regular tires. The reason is that this type of tire consists of premium materials and construction. These factors contribute to their benefits. So, if the high price does not bother you, getting a folding bike tire is a worthy investment.

Lifespan

As mentioned, folding bike tires’ soft and flexible composition contributes to their short lifespan. Folding bike tires are more prone to wearing than regular tires, primarily when used on trails with many obstacles. Standard bike tires last longer than foldable ones, consisting of steel wire bundles and rigid rubber material.

But if you aim to have a better riding experience, sacrificing the lifespan of your bike tire for one that provides a smoother ride is ideal. (source)

How To Install A Folding Bike Tire

Whether or not a folding bike tire is easy to install depends on your capabilities as a cyclist and mechanic. To help you make the process seamless, below is a step-by-step guide to installing a folding bike tire:

1. Make sure that the foldable tire has the correct size

Your folding bike tire must have the same size as the old tire you want to replace. You can find the tire size written on its side wall.

2. Unfold your foldable tire

Remove the folding bike tire’s tie and wait for it to take its shape. The creases from folding the tire should be gone after you unfold it.

When flattening your new tire, lay it down on a clean surface. This way, you can ensure that sand, dirt, stones, and any sharp object will not get inside it and damage the tube during installation.

3. Install the folding bike tire to the rim

Now that your tire is ready, take your rim off the bike and remove the popped tire and tube. It is also ideal that you check the rim to ensure that it does not have any significant damage.

Next, place one side of the folding tire to one side of the rim and press it down to install it. Do this step throughout the circumference of the bike rim until the entire tire covers it.

4. Insert the bike tube

Please get a new bike tube and do a quick inspection to ensure that it does not have any damage. Inflate the tube so it will be easier to hold. Inflating the tube will also give it a bit of shape, making it easier to insert into the tire. You do not need to inflate the tube to its maximum pressure. Just give it a bit of air so it will not be flat.

After inflating the tube, carefully insert it between the rim and folding bike tire, ensuring that it does not crease during the process.

5. Fix the tire into the rim

Now that you have installed the bike tube, the next thing you need to do is to insert the edges of the folding bike tire into the rim’s flange. You can do this by hand or using a tire lever. Regardless of how you want to fix the tire into the rim, ensure you are not pinching the bike tube, as it can cause holes.

6. Inflate the tire

Finally, inflate the tire to the recommended pressure and install it back onto your bike. (source)
