Wheels and tires — general information and designation (Opel Corsa C)

General information

1. The tire sizes approved for installation on the models described in this Manual and the standard air pressure in the tires for the front and rear wheels are given in Specifications to the Chapter "Controls and operating techniques". The plate with the values of the standard air pressure for a specific model is pasted on the inside of the fuel filler cap. Tires of the same size, the same design, with the same tread pattern and the same manufacturer must be installed on one axle of the vehicle. The authors of this Manual strongly recommend that, if necessary, the entire set of tires be replaced at the same time.

Tyre designation

Example: 155/80 R 13 79 T

• 155 — Tire width in mm
• 80 - Cross-sectional ratio in % (the height of the cross-section of the tire is 65% of the width)
• R — Radial design
• 13 — Disc diameter in inches
• 79 — Load capacity indicator (for example: 79 corresponds to 437 kg)
• T — Designation of the permissible maximum speed (the decoding of the letter designations is given in the Specifications)

2. The most optimal tire size for a specific model is installed by the manufacturer. Before installing tires of a different size on a vehicle, it is imperative to consult with specialists at an Opel service station. Remember that installing other tires may change the handling characteristics, affect the braking properties and the functioning of the vehicle's electronic motion control systems.

Note: When using tires of a different size, it may be necessary to reprogram the electronic speedometer and some other electronic systems. Do not forget to change the plate with standard air pressure indicators in the tires.

3. When using tires with a directional tread pattern, when installing them, it is necessary to ensure that the direction of the pattern matches the direction of movement of the car. As a rule, the direction of rotation is indicated by a special symbol (for example, with an arrow) on the sidewall of the tire.

4. Some types of tires have protective thickenings around the entire perimeter of the disk, designed to protect alloy wheels from damage. When installing such tires on regular steel wheels, only original protective/decorative caps from Opel can be used.

5. Some models may be equipped with a special compact type wheel or a tire repair kit instead of a full-size spare wheel. Remember that the compact type wheel is intended only to be able to get to the nearest service station - at the first opportunity, repair the damaged wheel and perform a reverse replacement.

Note: Similar requirements apply to the use of a spare wheel with a summer tire instead of a wheel with a winter tire. When using tires with a directional tread pattern, as soon as possible (if necessary) remount the tire so that the tread pattern direction matches the direction of travel.

7. When installing wheels with winter tires on a vehicle, they must fully comply with the design, size and load capacity of the wheels being replaced (see Specifications to the Chapter "Controls and operating techniques"). It is permissible to install only the front or only the rear wheels with winter tires, but the greatest effect is achieved by replacing the entire set of tires - when driving on snowy or slippery roads, winter tires have better grip and traction characteristics.

Attention: The maximum permissible speed for winter tires is lower than for summer tires - follow the recommendations of tire manufacturers and the requirements of the Road Traffic Regulations (RTR)!

8. If necessary, anti-skid chains can be installed on the front (drive) wheels of the vehicle. The chains must match the size of the tires and be securely and tightly fastened to them. After installing the chains, remove any excess links to avoid damaging the body surfaces when the wheels rotate - the vehicle must be driven at low speeds of up to 50 km/h. If the caps of the steel wheels come into contact with the chain links, the caps must be removed. The authors of this Manual recommend using Opel-approved small-link anti-skid chains, the height of which, together with the connecting link of the chain, on the running surface and on the inside of the tire does not exceed 15 mm. Anti-skid chains are used when driving on heavily snow-covered road surfaces and are not effective on dry roads, in addition, this may lead to chain breakage.

Note: Local regulations may prohibit the use of chains - please check with your local authority for current regulations.

Note: For emergency wheel (compact type) and for tyre sizes 185/55 R 15, 185/60 R 15, 195/45 R 16 and 205/40 R 17, the installation of snow chains is prohibited! If, in the event of a puncture of a front tyre, it is necessary to continue driving with snow chains, the compact type wheel must be mounted on the rear axle and the rear wheel on the front axle.
