As I understand it a standard Z4 has run flat tyres. The Z4M however (as I'm sure you already know!) has normal tyres, but rather than having a spare wheel for when you get a flat, you get a pump and a bottle of sticky goo which is supposed to seal the puncture from the inside out. My question is this... To adjust tyre pressures on my Z4M I've been doing it at my local garage which charges £1 a go. Now don't get me wrong, I'm reallyno fussed about a quid, bit I was just wandering if its actually possible to use the supplied pump to check the tyre pressure and top it up here and there without attaching the goo bottle thingamee-wotsit?
