Does the i3 need 175/60 rear tires?

[Dick Bunce]

Bought my 2018i3 a month ago. Dealer just told me I have 155/70 tires all around, all with lots of tread wear remaining. Does it matter? Must I replace the perfectly good rear tires with 175/60?

No. Base i3s came with 155 all around. Your door sticker should indicate what was originally installed.
