Sent in by MF reader Richard W: It looks like we’re starting to see the new tire pressure monitoring sensors showing up on R56 MINI in the United States. According to

>The phase-in has changed slightly: 20% of all new cars must comply by Sept. 1 of 2005, 70% by Sept. 1, 2006 and 100% by Sept.1 of 2007. NHTSA did not address RMA’s petion on reserve inflation pressure although they indicated they will in a separate rulemaking.

That makes them mandatory on all vehicles sold in the US effective Sept 1, 2007. It looks like it is affecting MINIs built during the end of August.

Something that you might want to keep in mind when looking at aftermarket wheels.

Thanks Richard for sending this in!
