330e Wheel Size vs Range

[pault76]

Hi, As an owner of a 67 model plate 330e I’m wondering if any other 330e users on 18 inch wheels can help.

I’ve recently popped on the winter steels, as such the original 17s are stored safely away. I’ve been thinking about selling them whilst off the car and upgrading to a staggered 18 setup (used to have it on an old F30 and liked the handling).

With only 16-19 miles range on electric, any loss in range is likely to be felt a bit more than an EV with 200 miles range... Am I looking at a noticeable loss in range were I to upgrade wheel sizes?

Current tyres are 225/50/17s and looking to move up to 225/45/18s front and 255/40/18s rear.

Thanks!
