New System Description





BMW Run Flat Tire (RFT) Technology which was first introduced on the Z8, is standard on the (E85) Z4. RFT technology offers large advantages to the customer in dynamic stability with slow or sudden air pressure loss and Deflation Warning. In addition, the spare wheel and jacking equipment in the trunk is deleted which provides additional storage space.
A tire with back up running ability (RFT) will be differentiated from a nonrun flat tire by the encircled letter designation on the sidewall (for example: RSC Run flat System Component).
