Good job EVs barely use their friction brakes.

How are the anti EV brigade going to spin this one? They jump up and down about weight although roads are designed for heavier vehicles, and tyre wear etc.

That reminds, I think I will be having to replace my tyres this year at the service time, mind you 22+ thousand miles off one set is better than what I get out my RAV 4 tyres generally so I can’t really complain.

I wonder if the author is of the anti-EV brigade given this statement

"Dr James Parkin, from the University of Southampton and lead author of the study published in the journal Particle and Fibre Toxicology, said: “People generally associate pollution from cars as being from exhaust pipes and think of electric vehicles as having zero emissions. However, electric vehicles still produce particulate matter due to friction and wear of the road, tyres, and brakes."

Having had a quick scan of the study I wouldn't say the author is of the anti-EV brigade at all, as the study is more into highlighting that the emissions from exhaust are not the only ones that are of concern and that the switch to EV's wont cure the problem of particulates that can cause us harm.

Very true, and the kinetic energy in a vehicle is half mass x velocity squared, so regen does even more of the work than we may realise.

30mph vehicle has 2.25x as much energy as 20mph, so even if you do have to brake, the re-gen can remove much of the energy first. And with one pedal driving, if you can avoid using the brakes, then the last bit done by the friction brakes is minimal. For example 30mph has 100x the energy of 3mph, rather than an assumed 10x.

I get the issue of tyre wear, but the article seems to focus too much on brakes and EV's .... weirdly?

I got 20k out of the set that came with my iD4. Considering EV-specific tyres don’t have as much tread as normal tyres to start with that isn’t bad at all.

Replaced the OEM Hankooks with e-Primacy. I wasn’t too bothered about EV-specific tyres but the Michelins were too cheap to turn down. So far performance has been great with the new tyres being much better getting away from the line. Horrendous in snow though, but the Golf GTE has CrossClimates on so I just use that when it’s white out.

38k miles and I am still on my original OEM tyres on my ID4. Confident that they will get through the 4yr service and MOT in April.
But then, I always get good mileage out of tyres.

I shall change them when the first one gets down to 3mm or before next winter which ever is first.
