I'm planning to remove the Bridgestone runflats from my '05 Z4 2.5L within the next week or so. I'll be buying a spare and a set of Dunlop Direzza Sport Z1 Star Specs. My old tires just don't grip well on an auto-x course. My question - Is removing a runflat tire from the wheel any different from removing a conventional tire? I work at a non-BMW German new car franchise and my techs are experienced with conventional tires. I'm just curious if there is anything they need to be aware of. Thanks, Myron M. Ft, Worth, Texas
