Comment on How to make an EV tire that won’t pollute the environment

  The cars might be, but their weights are their weights and that is an apples to apples comparison in the context of

  And now to make lighter EVs that don't wear on the road so much.

    Why not just compare the model 3 to an 18-wheeler then? Those weigh way more. Would have made his point better.

    And it’s a completely meaningful comparison, as long as you throw away the fact that different vehicles are used for different things.

      They’re designed for different things. While I’ll agree that the many F-150 drivers are using them for their appropriate grade of work or towing, I’m guessing there are more F-150s that are used as grocery-getting-pavement-princesses than all the Tesla Model 3s ever sold.

      In that way, F-150 is identical to Tesla Model 3 as far as use case.

  Alternatively, the model 3 is ~700 lb heavier than a Toyota Camery (which is actually a vehicle with the same use case as the Tesla)

  Seriously. We are talking about tire tread compared to weight. Both use multiple sizes of tire depending on the year/model. There are a few that overlap in diameter to get the closest to comparison but they still have a very different width. We are talking about a 235/35R18 vs a 235/75R18. That is a huge difference in wall height/aspect ratio and changes how the tire gives under power. Those numbers massively change depending on model as well. Something like an f150 raptor could have a 315/70R17, almost a foot wide. So comparing just the weight and saying they are close enough is far from a fair comparison.

    A model 3 to an f150 is absolutely apples and oranges.

    Seriously. We are talking about tire tread compared to weight.

    Are we? I thought we were talking about tire particulate pollution. Why have I never heard the conversation raised that truck tire pollution is a problem? Why is it only EVs that its suddenly an issue?
