me not using spare tyre since lng long time ago...my previous swedish marque chenge to 4port brake kit,and the ori spare tyre cannot accomodate due to big brake kit,and i just remove the spare tyre from the car,another way to reduce weight summore
As for current F10,am using RFT but soon will change to non RF tyre,what i do is just keep a small compressor in the car,if kena small nail,then use the compressor for emegency and go to nearest tyre shop
