Why it’s first: * — BMW and Mini: the star is BMW's approval: built to BMW's rolling-circumference tolerance so the driven wheels turn as one through the differential (and the transfer case on an xDrive). BMW says star tyres on all four, never a star mixed with a non-star. The approved sets come before the rest.
⚡ Electric specif yours is electric or a plug-in hybrid, this is the set to have — it carries the battery's extra weight, rolls easier for more range, runs quieter, and copes with the instant pull of an electric motor. On a petrol or diesel car the standard set does the job.
