FAQ

The measurement of motorcycle tyres is based on a system that indicates the size and characteristics of the tyre itself. The size of a motorcycle tyre is typically expressed in a sequence of numbers and letters that indicate width, aspect ratio, construction type, and rim diameter.

A typical motorcycle tyre size, such as 120/70 ZR17, breaks down as follows:
1. 120: tyre width in millimeters (120 mm)
2. 70: aspect ratio (sidewall height is 70% of the width)
3. ZR: speed rating and construction type ("Z" = over 240 km/h; "R" = radial construction)
4. 17: rim diameter in inches (fits a 17-inch wheel)

The second number in motorcycle tyres represents the aspect ratio, which is the height of the tyre’s sidewall expressed as a percentage of the tyre’s width. For example, in a tyre labeled 120/70 ZR17, the second number (70) means the sidewall height is 70% of the width (120 mm).

Wider motorcycle tyres can provide better grip, stability, and comfort, especially for sport or touring bikes. They offer a larger contact patch with the road, improving traction and absorbing road imperfections. However, they can reduce agility, add weight, increase costs, and may cause compatibility issues with certain bikes. The choice of tyre width should depend on riding style, bike design, and manufacturer recommendations to balance performance and safety.

Motorcycle tyres should be changed at a specialized workshop or by a professional mechanic. These experts have the necessary equipment to ensure that the new tyres are mounted correctly and balanced for safe riding. Find the nearest Metzeler dealer to you.

The cost of tyres depends on the type of tyre and its quality. The size of the tyre, the type of motorcycle, and the specifications required by the manufacturer can also affect the cost of motorcycle tyres.

Yes, motorcycle tyres need to be balanced. Balancing the tyres is essential to ensure a safe and comfortable ride. If the tyres are not properly balanced, the motorcycle may vibrate, especially at higher speeds, causing stress on the suspension, increasing tyre wear, and reducing stability.
Balancing helps to evenly distribute the weight of the tyre and wheel, reducing vibrations and improving handling, tyre lifespan, and safety during the ride.

Yes, a tubeless motorcycle tyre can be repaired, typically for small punctures. The repair process usually involves using a tyre plug kit, which seals the hole from the inside. The general steps include:
1. locate the puncture: identify the hole, which is typically caused by nails or sharp objects
2. prepare the tyre: clean and enlarge the puncture using a reaming tool to create a smooth surface for the plug
3. insert the plug: insert the rubber plug into the hole using an insertion tool, then trim the excess
4. check for air leakage: reinflate the tyre to the recommended pressure and check for leaks

Yes, it is possible to temporarily plug a motorcycle tyre in case of a puncture using a repair kit. These kits typically include a rubber string or sealant to insert into the hole, sealing it temporarily. However, this is not a permanent fix and should only be used to reach a mechanic.

Plugging a motorcycle tyre is a temporary solution to a puncture and can be done with a tyre repair kit. However, it's important to note that this method is only suitable for small, punctures in the tread area, not on the sidewall. Here how to plug a motorcycle tyre:
1. remove the wheel (if necessary)
2. deflate the tyre
3. locate the puncture
4. ream the hole
5. insert the plug
6. trim the excess plug
7. reinflate the tyre
8. check for leaks

Motorcycle tyres can be either with an inner tube or tubeless, but most modern motorcycles use tubeless tyres. Tubeless tyres do not have a separate inner tube; instead, the tyre itself forms an airtight seal against the rim, keeping the air inside. This type of tyre is safer in the event of a puncture, as the air escapes slowly, allowing the rider to stop safely. Additionally, it is easier to repair since there is no need to remove an inner tube.

Tubeless motorcycle tyres are generally safer than tubed tyres due to several advantages. They reduce the risk of sudden air loss because they can self-seal after a puncture, allowing you to ride for a short distance. Tubeless tyres are also easier to repair with tyre plugs, eliminating the need to remove the tyre. They avoid the risk of "pinch flats," improve heat dissipation, and offer better overall performance, especially at lower pressures. While not immune to issues, tubeless tyres are typically more reliable and convenient for regular riding.

Tubed motorcycle tyres are not inherently dangerous, but they do have some limitations compared to tubeless tyres. The safety concerns generally arise from certain conditions or issues that can occur with tubed tyres:
1. slow leaks: tubed tyres are more prone to slow leaks because of the inner tube, which can be punctured. If the tube is punctured and the rider doesn't notice it quickly, it can lead to a flat tyre, causing unsafe riding conditions. With tubeless tyres, the seal often allows air to remain in the tyre even after a puncture, giving more time to safely stop
2. risk of tube pinch: if the tyre is under-inflated or improperly mounted, the inner tube can be pinched between the tyre and the rim, leading to damage or punctures. This is less of a concern with tubeless tyres, as they have a more secure seal against the rim

Motorcycle tyres heat up with the throttle and brake, in a straight line. More specifically, most of the heat in the tyres is generated during hard accelerations and strong braking, with the bike as upright as possible.

Breaking in new motorcycle tyres requires a simple ride of at least 100 km, following these guidelines: start slowly, accelerate and brake gently, and corner without excessive lean angles. Gradually increase the stress on the tyres until you become accustomed to their performance.

The small strips of unused rubber that extend from the outer edges of both tyres are commonly known as "chicken strips" among motorcyclists. These strips are visible on brand new tyres and are a remnant of the manufacturing process. They form because the tyre was produced with a smooth surface that hasn’t yet made contact with the road. "Chicken strips" are usually visible only on new tyres and disappear as the tyre is used, with the rubber wearing down and adapting better to the road surface.

Cleaning your motorcycle tyres is essential for both appearance and safety. To clean them, start by rinsing the tyres with water to remove dirt and brake dust. Then, use a mild soap or tyre cleaner and a soft brush to scrub the surface, focusing on the sidewalls and tread. Rinse thoroughly and dry the tyres with a microfiber cloth. Optionally, you can apply a tyre shine or conditioner for protection against UV rays but avoid applying it to the tread. Regular cleaning also helps you inspect the tyres for damage, ensuring both safety and longevity.

The ideal air pressure for a motorcycle tyre depends on the specific make and model of your bike, as well as the type of tyre you are using. Typically, the recommended tyre pressure for most motorcycles ranges between 30 to 40 psi (pounds per square inch) for the front tyre, and 32 to 42 psi for the rear tyre. However, it's essential to check the owner's manual or the tyre sidewall for the exact recommended pressure for your motorcycle.

To measure the tyre pressure of a motorcycle, first unscrew the cap on the valve and connect the pressure gauge hose to the valve. Now you can see the air pressure value inside the tyre. This value should be compared with the values listed in the maintenance manual provided by the motorcycle manufacturer.
