Wheel/tire question

for the 2004 3.0, the spec sheet for the sport package option says 225-40-18 front and 235-45-18 rear, Tire rack has the same front size but rear as 255-35, what is the correct size? Anticipating delivery next week.

235 is correct I believe. You can find the width on your current tires.

245/35-18 (not 235/45-18) may have been the sport package tyre on the Z4 3.0i in 2004 (as this size was commonly used on the E46 then), but 255/35-18 is actually closer to 225/40-18 in diameter, so is typically the staggered rear tyre of choice now on many BMWs. The 2006+ Z4 3.0i and si sport were certainly fitted with the 255/35-18 rear tyre.
