Great video. I’m curious about winter tires for EVs. If you check manufacturer websites, they simply say “made for EVs”. I understand that trying to provide all these benefits as well as a capable cold weather/ice/snow tire would be difficult, I’m sure. I’ve gone to looking at aerodynamic wheels for my PHEV to at least gain back some rolling efficiency with the heavier winter tires.
I did not know the weight of my original FWD HEV wheels and ended up replacing them with another set of OEM Hybrid wheels from 2014 used for snow tires made by the same manufacture vehicle I owned for years. The old set was 23 lb and the the OEM alloy wheels with aero covers are actually only 19 lb total now I can weight them after been taken off tires. What I found is odd to me: the OEM is quieter maybe due to the offset as the old set had +51mm (further out to the fender) and the OEM is +54mm but I find the car feels much grounded, better cornering and the regen break is producing more energy to fill up the battery when breaking. they even have better hydroplaning resistance than the lighter rim set. Lighter wheel "should" be more energy efficient during acceleration and that does show a bit as well; however, when costing on the road the extra weighted wheels actually produces more momentane and requires less need of applying extra energy to keep up with the constant speed. At the end, with my slow acceleration, relaxed driving style and the small hilly countryside terrain I drive in daily about 60miles/100KM per day, it's is just very little better than the OEM set so far! Interesting results
I would say they are just making better tires now. Its being marketed to EVs but should be on most cars. Who doesn't want quieter more fuel efficient tires!
I love the innovation of EV that requires tire manufactures to make tires that are "compatible" for EV vehicles. I am using a set of "Made for EV" All-Weather 3PMSF rated tires with 100,000KM/60,000 miles warranty (now used on Europe Volvo EV). Because they are designed to be compatible with EV, I found that the tread actually also last longer if the tires are manufactured with "Full Depth Treads". My first H-Speed set had 6mm left just before they reach the end of the warranty and sold them for 50% of what I paid for to purchase the same second set V-Speed (softer compound/harder sidewall) now at 7-8mm tread depth after 50,000KM/30,000 miles. For less rolling resistance, since these much safer All-Weather tires are not as efficient as the OEM Micheline Energy Saver A/S (usually with less tread depth/better millage as a factory tires) from my FWD HEV, by adding 4psi on top of the normal pressure level it closes the millage differences to none and still more comfortable and safer in any poor weather conditions.
Great video.

Interesting parameters. I suppose it's all about trade off. Longevity, rain traction, cost? Thanks for the primer.
