Me and a friend were talking about this a few evenings ago. My first car (back in 1991) was a MK2 Escort, this had 13 inch diameter wheels. My current car's (Ford Focus) brake discs are 363mm (so over 14 inches)! Edited by zetec on Sunday 26th July 12:32

Do they never look at the weight of BEVs compared to their ICE equivalents?Aside from it being bks, as alluded to by a poster above when referencing trucks, it's all about ground pressure....and that's weight/footprint....and footprint has grown faster than weight - bigger wheels = a longer tyre footprint than a smaller wheel, and wider tyres = yes of course it does....so a 2.5t SUV with 21" 285-section tyres probably has a similar or lower footprint than your Dad's old 1t Cortina with 165-section tyres on 13" wheels.Yes. Agreed. But I wasn't comparing Cortinas with 2.5t SUVs. I was talking about the typical SUV which could be a RAV4 or a CHR or a Kia Sportage etc with an average (non SUV) BEV, which could be an Ioniq5 or an Ioniq 6 or a Tesla Y etc.To take two that are of a similar footprint and physical size:(data from quick search)Model Y - 2,088 kgRAV4 - 1,630 kgModel Y - 255/35R21 - could be as small as 19RAV4 - 235/55R19Heavier and bigger wheels and tyres, but I do not say that EVs are bad, only that they are conveniently ignored when people bang on about SUVs being too heavy and ruin the roads.
