Think i may have a puncture in one of my tyres as it is going from 30psi to about 18psi in about 2 weeks. Ima bit paranoid about having tyre removed now tho as i had to have a new tyre done at audi when it was new and they ruined my wheel on the machine left big dents in the rim where the machine had gripped the wheel. (Made them replace with brand new wheel and tyre.) But... a puncture needs sorting nonetheless - has anyone ever used event mobile tyres??? my wheels are absolutely perfect and never been marked or repaired and although i would like to get the puncture fixed i do not want to even chance the wheel getting damaged. Tyre machines make me cringe cos i dont know how they manage to pull the tyre over the rim without damaging the wheel?!?!
