With Boxster alloys they are run flat anyway. With only 2 psi in one front the car drove fine & the sidewall was stiff enough to keep shape! Who needs a spare with these tyres. Joke is it went for MOT like that & passed!

I have a 944 S2 which has been fitted with 17" 205 and 255 wheels. The space saver rear wheels is however currently the original 16" collapsible 20 year old space saver. I take it that this will not work with the larger wheels...i see many 944,s with larger wheels fitted now, what do you all do with regards to spare wheels etc. |

The outside diameter off the wheels should remain the same, and there for not propose much off a problem using the space saver in a jam. However were or not 20 year old rubber is safe is another issue all together. I went with runflats all round a bit heavier, but no chance off a blow out and can be used 2 get home. Iv actually drove around on one 4 3 days without relising due 2 a leaky valve after fittment. |

That's why the tyre manufacturers always recomend tyre pressure sensors when using run flats. I believe you only notice when you start giving it a bit in the twisty bits and that's a bad time to find out you have a flat tyre. |

If you don't have tyre pressure monitoring systems on your car, run flats can be really dangerous. I know this from personal experience! |
