Tips for wheels
A : Geometry value
B : Support value
C : Identical axle
I : OE wheel with a 30 ET
II : With new wheels, ET = 0
Tips for fitment
- Check the nuts and bolts are adapted to the vehicle.
- Try to mount the wheel on the vehicle before mounting the tyres.
- Check he fitting after 200km.
- Some wheels (called "winter") are especially designed to reresist to the salt effects.
- Make sure the load index corresponf to the vehicle (in particular for SUV).
Care tips
- Regularly wash the wheels (every 15 days) with water and soap (maximum 1 bar if you use high pressure wtare jet).
- Avoid classic wheels cleaners (because they have an acid pH, caustic soda and other alkaline components).
- Avoid cleaning wels with hard brush and in automatic car wash stations.
- Avoid polish and other diluents.
Terminology
Spigot: part in the centre of the hub that you rest inside the centre of the wheel. It is different for each vehicle.
Wheel width: generally, a model in 17' will always have the same width. The tuning wheel never has the same width and same offset (ET) as the orginal alloy wheel.
Number of holes: 4 or 5 holes for ars
PCD: diameter of the studs from the centre of the wheel.
Offset (ET): is the distance between the imaginary centreline of the wheel (as viewed from behind the wheel as it would roll away from you) and the inside face that bolts up against the wheel hub on the car. Generally goeas from ET15 to ET60 (except in extreme tuning where ET0 is fitted). Higher the offset is, less materia there is betwen the hub et wheel's axle. It is usually not written on the orginal steel wheel and is not necessary to place an order.
Lip depth: rim border depth.
