What do you do if dressed up and on your way to an event, then BOOM! You have a flat tire. What next? Change the tire or drive to your event and then later on to the work shop and get it repaired? Below explains the advantages and reasons behind BMW creating run-flat tires on most of their new models.
The following text was published on babybmw.net, an UK fans forum, in response to a customer’s concern.
BMW aims to provide our customers with a premium product that provides ultimate safety with optimum performance and it is always a concern to receive feedback of this nature.
We chose to include Run-flat technology on our vehicles for the following reasons:
- It is dangerous to stop on any road to change a tyre, especially on a motorway or at night.
- There is no need to have to wait for a breakdown service to arrive.
- Safety and security of the driver and passenger(s) is maintained.
- Alloy wheels are difficult to detach from steel hubs.
- On most cars the spare is under the contents of the boot, and uses boot space.
- It can be tricky to line up the wheel bolt holes with the hub screw holes and match the thread.
- The dirty punctured tyre needs to be removed and stored in the boot.
- Another puncture before the punctured tyre is mended means one is stranded.
- A driver can continue for 150 miles at 50mph with a punctured Run-flat tyre.
All of our vehicles that use Run-flat technology have their suspension and braking components set up to accommodate Run-flat tyres. Should you decide to change to non Run-flats, it may alter the driving and handling characteristics of your vehicle. It is for this reason that this modification is not recommended by BMW as a manufacturer.
However, it is possible to have standard tyres fitted. You will additionally need to purchase either a spare wheel with jack and brace set or a mobility kit which can be ordered from the Parts Department of your nearest BMW Approved Dealership.
