Tire maintenance | Mitas

Tires are the only part of a motorcycle, which are in contact with the road. Safety in acceleration, braking, steering and cornering thus depend on relative small contact area between the tire and road. This is a reason that tires should be maintained in good condition through all lifetime. Tires may only be replaced by the authorized personnel. Changes in tire size, type and construction should not be made without advice of a motorcycle or tire manufacturer, while wrong tire fitted can have a very strong negative effect on motorcycle handling, safety and wear. Always read the motorcycle manufacturers’ handbook. New tires have very smooth surface. It is recommended to drive especially carefully for about 100 km to make tire work properly. Drive reasonably. Excessive acceleration, braking and cornering shortens tire life considerably.


Assure a sufficient distance between the individual motorcycle parts (mudguards, forks, transmission chain) and the tire mounted on the rim.

During rides at higher speeds the outer dimensions of a tire enlarge as a result of a centrifugal force. The increase can be even larger with a diagonal tire; therefore, do not change the nominal tire dimensions.

Due to a danger of a contact between the tire and the motorcycle parts, and developing uneven wear and tear, make sure that the wheel base is correctly adjusted after transmission chain becomes worn-out.


Suitable flaps have to be used with spoke wheels. Regularly maintain flaps since the protruding spoke head can damage and puncture the tube.

Correctly balance the tire on the rim and regularly examine it. In Slovenia, the legally specified tread depth amounts to 1 mm (in Germany to 1.6 mm) over at least ¾ tire tread width, however , we recommend to replace the tire earlier, since worn-out tires are more likely to get damaged, and have poorer road grip, particularly on wet surfaces. Damaged tires can be very dangerous and should be immediately replaced.

Immediately eliminate rocks and nails pushed into the tire tread, since they can puncture the carcass, cause a failure and, consequently, an accident. The main benefit of a tubeless tire is that despite being punctured with a nail, an abrupt pressure drop is not possible. Yet, if a driver is not aware of a tire failure and continues the ride, the damage can spread and become hazardous.

If the pressure drops, the tire has to be removed from the rim and inspected, the reason for a pressure drop is to be established prior to any repair.

We strongly advise against any repairs of the tire shoulder and sidewall area.

Furthermore, we strongly advise against any repairs of the P speed category tires or higher.

It is not allowed to repeatedly use a damaged TL tire with a tube.

The tire can behave differently in contact with oil or fat, therefore clean it with a cloth soaked in benzene.

MITAS tires are manufactured with a minor mass imbalance. To achieve a perfect mass balance of the tire and rim construction an additional balancing procedure is required for driving at higher speeds.

Motorcycles may be used only with the rims specified by the vehicle manufacturer. The use of suitable rims is of importance for a stable ride and other driving characteristics. If the tire is mounted on a too narrow or a too wide rim, this can lead to a change in the tire tread shape, which negatively impacts the driving characteristics in general.


Different factors can cause an abnormal tire wear and tear:

Insufficient pressure or overload can deform the surface and result in incorrect wear. It can come to a sudden defect in the carcass as a result of excessive bending and a sudden air release.

High speed, heavy accelerating and braking.

The temperature of driving surface (higher temperature results in higher wear).

A rough driving surface (the rougher the surface, the higher the wear and, consequently, the shorter the service life).

Mechanical irregularities such as deformed wheels, incorrect brake adjustment, poor-quality shock absorbers, a too large gap between the wheel bearings, etc.

Unbalanced rotation mass of the tire and rim construction.

Incorrect adjustment of the rear wheel when replacing or adjusting the transmission chain. Each rotation of an incorrectly adjusted rear wheel causes additional and uneven wear of the tire tread surface and has a negative impact on driving characteristics of a vehicle, which can lead to a loss of stability during the ride.
