Wheels and tyres

The new BMW 3-Series Sedans are factory-fitted with attractively styled, high-quality alloy wheels. The BMW 335i and BMW 328i run on 17-inch Star-spoke wheels carrying 225/50 R17 tyres. The BMW 320d and BMW 320d EfficientDynamics Edition diesel models ride on 16-inch V-spoke or Streamline-style alloy wheels and 205/60 R16 tyres. The rolling resistance of the tyres in the basic sizes quoted above has been reduced yet again - this time by approximately 15 per cent, while still maintaining the customary high BMW standards of driving dynamics.

Model versions of the new BMW 3-Series fitted with 17-inch - or larger - wheels are supplied as standard with run-flat safety tyres and the Tyre Puncture Warning System (TPWS). This solution provides additional convenience and safety benefits. Should a puncture occur, there is no need for a roadside repair or tyre change. What's more, the warning system informs the driver of any loss of tyre pressure, so he can usually take precautions to avoid being stranded. Even if a tyre becomes fully deflated, the vehicle maintains directional stability and can continue to be driven on the run-flat tyre at an appropriate speed. A further advantage of this system is that a spare tyre and a jack can be dispensed with, thereby saving weight and creating more boot space. Vehicles which do not have run-flat safety tyres are equipped as standard with the BMW Mobility Set, including an air compressor, tyre sealant and other breakdown accessories.
