All the online forms suggest my tyre size should be 155/70/r19 tyres. Tyre price and available option vary a lot depending on the size, what width and profile options will work on the turbine wheels?
To date, only Bridgestone makes tires of the size and low rolling resistance property needed by an i3. The base BEV model with the 427 pizza slice wheels had 155/70/r19 tires mounted both front and rear. Some online tire Websites seem to suggest that this is the situation for all i3's whereas all but the BEV model with 427 wheels use 175/60/r19 tires on the rear.
Bridgestone did offer both all-season (Ecopia EP500) and summer tires (Ecopia EP600) in 175/60/r19 in the U.S. with the all-season version being what BMW installed originally in the U.S.
For the best driving range (i.e., the lowest rolling resistance), the i3 tire choice is limited to the Bridgestone Ecopia.
