FAQ

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

A typical motorcycle tire size, such as 120/70 ZR17, breaks down as follows:
1. 120: tire 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 tires represents the aspect ratio, which is the height of the tire’s sidewall expressed as a percentage of the tire’s width. For example, in a tire labeled 120/70 ZR17, the second number (70) means the sidewall height is 70% of the width (120 mm).

Wider motorcycle tires 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 tire width should depend on riding style, bike design, and manufacturer recommendations to balance performance and safety.

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

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

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

Motorcycle tires can be either with an inner tube or tubeless, but most modern motorcycles use tubeless tires. Tubeless tires do not have a separate inner tube; instead, the tire itself forms an airtight seal against the rim, keeping the air inside. This type of tire 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 tires are generally safer than tubed tires 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 tires are also easier to repair with tire plugs, eliminating the need to remove the tire. 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 tires are typically more reliable and convenient for regular riding.

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

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

Breaking in new motorcycle tires 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 tires until you become accustomed to their performance.

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

The ideal air pressure for a motorcycle tire depends on the specific make and model of your bike, as well as the type of tire you are using. Check the owner's manual or the tire sidewall for the exact recommended pressure for your motorcycle.

To measure the tire 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 tire. This value should be compared with the values listed in the maintenance manual provided by the motorcycle manufacturer.
