A tire’s function is to reliably transmit the propelling and steering forces to the road and to absorb all impacts acting upon your vehicle driving on an uneven surface. Tires have a very significant impact on the safety, reliability and ride comfort of your vehicle.
Tire air pressure
- Check tire air pressure regularly, at least once every 2 to 4 weeks. The pressure must be checked when the tires are cold. Even if the tires are heated only slightly, the pressure measurement will be inaccurate..
- If you lose or damage the valve elements, replace immediately. Tighten all valves properly and check whether the function surfaces are not damaged.
- Check air pressure in the spare tire regularly. A rule applies that the spare tire pressure must be about 0.5 atmosphere higher than the prescribed pressure. Adjust the pressure after the spare wheel has been fitted to an axle.
|Example ||Possible cause |
|Grater wear in the tread center ||The tire pressure is too high |
|Greater wear in the treat shoulders ||Greater wear in the treat shoulders |
|Considerably worn patches around the tire’s circumference ||Defective suspension, Defective shock absorbers, intensive braking |
|The tread worn on one side ||Incorrect wheel alignment |
- Check regularly whether the tire has the prescribed pressure and whether it is not damaged
- don’t forget that every tire has also its inner part which may be checked by a specialist with necessary technical tools only,
- have the tires checked by a specialist at least 4-times a year, to see whether they are OK.
Don’t forget that even new tires will be worn out quickly unless any defects in the steering and chassis are not rectified by a specialist !
Tires must be replaced at the latest when the worn our tread has reached the minimum height of 1.6 mm.
- To ensure correct functioning, we recommend to replace summer tires already when the tread height is 2 mm, and winter tires when the tread height is 4 mm.
- In wide tires the tread height must not be less than 3 mm.
- When a car or a trailer is to be unused for a protracted period of time, relieve weight on the tires and cover the tires
- Replace tires of mobile homes and less frequently used tires after 5 to 7 years!
- Use spare tires older than six years only in emergency situations!
What does the alphanumeric marking 195/65 R 15 V on the tire mean?
|195 ||the tire width ||Irrespective of the tire construction, this information is always given in mm |
|65 ||the tire height-to-width ratio in % ||This is calculated by dividing the tire height by the tire width in mm, and multiplied by 100 |
|R ||the tire construction identifier ||[R identifies a radial tire, D or a hyphen (-)identifies a diagonal tire |
|15 ||the rim diameter ||This is usually stated in inches, but may be also in mm. |
|V ||speed symbol ||The tire highest permissible speed is specified by an alphabetic code. |
Highest speed in km/h
