The classic split five spoke design is produced in classic “polar silver” paint, which is a great choice for the winter season. The paint is extremely hard-wearing and will protect the wheel from the harshest winter weather. Alutec are so confident with the quality of this wheel and its paint finish that they offer a 5 year guarantee for added peace of mind. This wheel is also TUV approved (European quality certification approval) for use on this vehicle which eliminates any insurance/warranty issues.

The wheel is great quality and is finished in polar silver paint which is particluarly hard wearing to cope with harsh winter conditions. The W10 is designed to take the original bolts and will generally also take an Audi centre cap. This wheel is also TUV approved (European quality certification approval) for use on this vehicle which eliminates any insurance/warranty issues and even comes with a 5 year guarantee on the paint finish. -TPMS, Lot’s of new vehicles are fitted with a tyre pressure monitoring system, this can be one of two systems direct and indirect. Direct systems are fitted with the valve sensor measuring the pressure of each tyre, the indirect system runs of the ABS calculating the rotation speed the theory behind this is the speed of the wheel changes when the tyre is deflating. You will find the sensor valves in the extras box below the tyres.
