This claim keeps circulating around and around and is not "EVs are producing more pollution", it's "if EVs are going at motorway speed, and if we only look at the pollution generated by the tires, then indeed they produce a little more".

But that's completely ignoring tailpipe emission, and the fact that in an urban setting it's still vastly more advantageous to drive an EV.
