EV are much heavier than petrol cars, maybe the offset weight will help regain some grip? Normal tires wear out so fast on EVs.

That extra weight will also mean that more force is required to accelerate and change directions.

The nimbleness of a vehicle can be expressed as the ratio:

(Tire Contact Area * Tire Stickiness) / Vehicle Mass

Increasing the vehicle's mass while making the tires harder will lead to longer breaking distances and will cause a vehicle to understeer at lower speeds.

Just staple Post-Its to regular tyres.

the staples will tear up roads and tires

it sounds like these wheels need to be much larger to offset the lower grip. Wonder how that affects the environment.

Much heavier than petrol cars if they’re not on a bespoke EV platform or designed poorly. Slightly heavier than petrol cars if they’re designed properly.

Eg a Model 3 and a Toyota Camry are the same weight and almost identical dimensions.

It’s weird to me the weight thing keeps coming up when discussing EVs but not the petrol cars which have been growing bigger and heavier for years.
