Maximum endurance.

Run-flat tyres on the BMW Z4 Roadster.

Run-flats make roadside tyre changes a thing of the past. Their specially reinforced sidewalls allow the car to keep going at up to 80 km/h - for as much as 250 km with careful driving. And because you no longer need to carry a spare, the standard run-flats on the BMW Z4 Roadster mean more luggage space and less weight. The tyres have also been tailored to suit the Z4 Roadster's sporty character and now offer a more comfortable ride - without affecting the car's agility.
