At Tyres.co.uk you can find some BMW i4 options with Pirelli P Zero (PZ4) or Hankook Ventus S1 evo3 with 245/45 R18 100Y XL in their 18-inch square-wheel fitment. As this is a factory fitment, other wheel options may require either run-flat tyres or different front and rear specification tyres. Ensure you check the BMW i4 placard or registration prior to purchasing.
To find the BMW i4’s tyre and tyre pressure information, check the placard on the driver’s side door pillar (by the open driver’s door). You will find approved combinations of wheels, tyres and the ideal pressure. Combined with the tyre sidewalls and BMW i4, there are several options of wheels that may have different fittments for the front and rear.
Replacing all 4 tyres will not be necessary for the BMW i4 as long as you make sure to match tyre combinations to the same axle. However, for xDrive models, BMW suggests that you maintain the same tyre manufacturer and design, though it will not necessarily be a requirement to purchase 4 new tyres. If you are only replacing 2 tyres, install the new set of tyres on the rear axle.
