I am at the cross roads of whether to go with the Pirelli RFTs that came with my car or switch to the non-RFTs. From the sounds of the comments going with the non-RFTs will give me a whole new experience. My wheels are the 21 inch rims (245/35/21 and 275/30/21) that came on the car from BMW. My only concern is the getting a flat and not having a spare.
Does anyone know of a 21 inch spare that would work on the 7 series? Or if the tire puncture inflation kit will work on the 21 inch wheels?
Thanks for your feedback!
