How run-flats work, why your BMW has no spare, what they cost to replace and whether switching to conventional tyres makes sense here.
Run-flats have reinforced sidewalls stiff enough to carry the vehicle's weight with no air. After a puncture you can typically drive about 80km at up to 80km/h to reach a safe place.
That is why many BMW, Mini and Mercedes models ship without a spare wheel. The tyre is the spare.
Stiffer sidewalls mean a firmer ride, which Nairobi's road surfaces amplify. They cost more to replace and fewer shops stock them properly.
They also must never be mixed with conventional tyres on the same axle, and the TPMS must be working, because you cannot feel a run-flat deflate.
Some owners do, for ride comfort and cost. If you switch, you must carry a spare or a proper repair kit, because you no longer have the run-flat safety margin.
We will fit either and we will be straight with you about what you gain and lose. What we will not do is mix the two on one axle.
If any of this raises a question about your own car, bring it in. The tyre safety check is free and takes ten minutes, and we will give you a written summary whether or not you buy anything.
Tread depth at three points, DOT dates on all five tyres, pressures set and wear patterns explained. Ten minutes, no charge.
See what's includedUsually not. Most manufacturers advise replacement, because sidewall damage after running flat cannot be reliably assessed.
Typically about 80km at speeds up to 80km/h. Check your vehicle handbook for the exact figure.
Yes, on all four wheels, but then you must carry a spare or repair kit. Never mix run-flat and conventional on the same axle.
