Tire wear causes massive pollution... now what?

As tires rotate, they squirm a little bit. That's because the cords pantograph through the footprint. That little bit of movement is like your hand laid flat on beach sand, then wiggling it - the hand sinks into the sand.

On concrete, there is mostly rubber bits rubbed off, but on asphalt, the stone particles are pushed deeper into the binder. Ever notice ruts in asphalt? The road is moving!

It sure is.

You've already forgotten Dieselgate ?

VW screwing the already unrealistic NEDC test cycle because its cars couldn't meet the test conditions - even at the lower-than-low test standards ?
Let alone during real-life road conditions (where NO diesel comes even close to meeting the pollution standards).

You could get a CNG up and run it on biogas in the Netherlands.
They're indeed light on their tyres, and take realistic tyre sizes rather than black road rollers .

I see that with GasDwarf you practice what you preach. Do you have a thread that describes living with the up! and the fueling infrastructure?

I liked the concept up!s because they were rear engined, but just like with the New Beetle, which went from the Polo to the Golf platform, VW dropped the ball.

phys.org/news: Car tires shed a quarter of all microplastics in the environment. Urgent action is needed

Every year, billions of vehicles worldwide shed an estimated 6 million tons of tire fragments. These tiny flakes of plastic, generated by the wear and tear of normal driving, eventually accumulate in the soil, in rivers and lakes, and even in our food. Researchers in South China recently found tire-derived chemicals in most human urine samples.

These tire particles are a significant but often-overlooked contributor to microplastic pollution. They account for 28% of microplastics entering the environment globally.

It won't be the CO2 that gets us, but the microplastics.

Don't remember there being much plastic in my tires. Could be, would have to take a sample for analysis and wouldn't suprise me if there was anymore
