2/5

Bridgestone Ecopia EP500

I think the wet performance of the tyres is poor because of the heavy weight of the fully electric car and the narrow width of the tyres.

Bridgestone Ecopia EP500

The car drives noticeably better now. The previous tyres didn't have tread wear that would be considered bad, but putting new ones on this small vehicle has made a huge difference in its comfort and handling.

Bridgestone Ecopia EP500

They are average. There are not a lot of choices for a BMW i3, so they sort of win by default.

Bridgestone Ecopia EP500

I haven't tested them in the winter because they aren't winter tyres, but they've performed well on wet and dry roads.

These tyres offer me great peace of mind and also great confidence protection on the road. I would comment more but I'm at work right now.

The new set feels almost the same as the last one. Not much of a surprise considering they are practically the same tyres.

175/55 R20 Explained

The BMW i3s has wider rear tyres. The system is simple. 175 is the width in mm and 55 is the percentage of the 175mm as the sidewall. In this case, it is 96mm. R20 states that it is a radial tyre with a 20-inch rim diameter. Thus, the overall diameter is 700mm with a sidewall of 96mm. The i3s can comfortably fit a 20-inch wheel due to the short sidewall. Tyres.co.uk sells this size.
