If you're sick of those dang TPMS alarms going off - MoS has added nitrogen - the benefit is it keeps your MINI tire at a more consistent tire pressure and less vunerable to the vagaries of our always fluctuating temperature.
Cost is $69.00 - the techs drained my tires of normal air last week and replaced it with nitrogen and green valve stem covers. Car corners a lot better and I'm getting better gas mileage.
See your SA (service advisor) at MoS if interested in having it done.
Krutty.
