Yes, though note that tire and road wear scale with the 4th power of the vehicle weight. If a person on a bicycle weighs 200 pounds and a person driving a car weighs 2000 pounds then the car is going to have roughly 10,000 times as much tire wear (and microplastic shedding) as the bike.

Now consider that people on bikes can even weigh less than 200 pounds and cars can weigh far more than 2000 pounds (I heard of a recent electric SUV that weighs 8000 pounds) and it becomes clear that bicycles are a complete non-issue, relative to cars. An 8000 pound car is equivalent to 6.25 million 160 pound bicycle + rider pairings.

Now consider the effects of 18-wheeler tractor tailors with a maximum weight upwards of 80,000 pounds. These things absolutely disintegrate their tires. If you’ve done any highway driving you’ve likely seen the shredded debris of tires on the shoulder of the road.

Edit: as an addendum I’d like to note that electric vehicles tend to weigh a lot more than ICE cars, by upwards of 1000 pounds. This is one of the reasons I’m dismayed at the rush to EVs: it’s going to accelerate the microplastic problem even as it reduces CO2.

also, why is it spelled that way?

British spelling of tire is tyre
