Depending on the model and configuration, Opel Vectra/Calibra cars can be equipped with different wheel rims and tires.
The discs have a pressing depth of 49 mm (the pressing depth is the distance from the plane of symmetry of the wheel to the surface where the wheel disc meets the brake disc).
The disc is centered on the hub using the central hole. To protect against corrosion, the disc's centering surface should be lubricated with bearing grease.
All wheel rims have lugs on the rim that prevent the tubeless tire from coming off the rim during sharp turns.
Attention! Wheel bolts for both regular and light alloy wheels have the same parameters: thread - M12x1.5, spanner size - 17 mm, tightening torque - 110 Nm.
The pressure in the spare tire must correspond to the maximum pressure in the rear tires.
All pressure values are given for cold tires. Do not reduce the pressure, which increases by 0.2-0.4 bar as a result of heating of the tires during driving.
The pressure in winter tires must be higher than the value indicated in the table (by 0.3 bar and more). Follow the winter tire manufacturer's recommendations.
For sporty driving, it is recommended to increase the pressure in all tires by 0.3 bar.
When towing a trailer, increase the tire pressure to the value given in the "full load" column.
If you install discs other than the factory ones, when using flat wheel caps, pull the long wheel valves inward. Make sure that sufficient airflow to the brakes is ensured through the ventilation slots in the discs.
