How lovely and clean London’s air will be once that nice Sadiq Khan’s Ultra Low Emissions Zone (Ulez) has been extended across the entire city and the Government’s ban on petrol and diesel cars has taken effect. Well, not quite. In fact, was there ever such a misnomer as a “zero emission vehicle”? Far from cleaning the air there is evidence that in one respect the adoption of electric vehicles could make pollution worse.
Electric vehicles might reduce carbon emissions (though far from eliminating them – indeed their manufacture involves carbon emissions). They might not have exhaust pipes spewing out nitrogen oxides. But growing attention has been paid in recent years to pollution from tiny particulate matter, which can penetrate deep into human lungs. Long-term exposure has been linked to an increased risk of heart disease and lung cancer. Trouble is that a fair amount of these emissions from cars emanate from tyres, not engines, and electric vehicles could possibly emit more because their heavier weight causes greater tyre wear.
While huge attention has been paid to emissions from exhausts, which quite rightly have been cleaned up over the years thanks to progressively tougher regulations, rather less attention has been paid to tyres. The Euro 4 regulations for petrol engines and Euro 6 regulations for diesel engines – on which Ulez is based – take little account of emissions from tyres; they are based on emissions from exhausts. Yet it doesn’t take too much to wonder if a heavy electric car driven around the streets of London could be emitting more tyre pollution than a relatively light petrol car.
Everyone wants clean air and air pollution has fallen dramatically in many respects over the past half century. But regulations which fixate on one form of pollution and ignore others ultimately help no-one.

It’s a means to an end.
Tires have Carbon emissions?
Who knew? [Why do they wear out anyway?]
Great, now they’ll install tank tracks on EVs and try to sell us on them.
Even bicycle tires emit Carbon.
But calling CO2 a 'pollutant' is disingenuous at best. Every human exhales CO2.
The market will prevail.
The market will determine the success of the Tesla auto market disruption
Aside from being electric, Tesla has revolutionized auto production and manufacturing
However, I'm not sold out on the belief that EV's eat up tires faster than ICE cars. I just recently replaced the tires on our EV after we put 24K miles onto it. IMHO that's not bad.
Don’t give them any ideas! They’ll either want to replace humans with “carbon free” life forms or require us to all wear carbon dioxide scrubbers and devices for our methane emissions.
Seems like NASCAR drivers, pit crews and regular race & practice personnel would be at greater risk than the general population.
I’ve gotten 30/40/50k miles from tires. Michelins used to be the best for tread life.
Tire design/construction is an art as tires have so many performance attributes to consider.
“Every human exhales CO2”
They’re working on that......whataya think covid was for?........and covid shots as well for that matter. 😏
24k miles? If I don’t get 80000 km’s on my tires, I don’t buy them again. That’s on a one ton diesel pulling trailers and lots of gravel. I weigh 10,000 lbs with no load.
EV’s aren’t “zero emission” vehicles. They just move all their emissions upstream to the power plant, and probably generate more emissions once you figure in the inefficiencies involved in generating the power constantly even when its not needed, and inefficiencies in transmission, storage, etc.
The government sponsors electric cars for their own reasons. Not for the environment. They can track and turnoff an electric car. They can listen to the driver. They can see what you did after you crash and die. They can see if you were speeding a month ago. They can track every cell phone that entered the car. They can track your listening by any source. The fact that its electric means they can control it. And monitor you. The environment is a very small reason for promoting electric cars.
Yes. The only relocate the emissions. Keep those nasty fumes out of my city and move them to China and India.
Another case of NIMBY.
Vehicles of the future!
Except not good on long trips.
Or in cold weather.
Or with heavy loads.
Or during peak usage times.
Or for high-mileage applications.
Or, or, or, or ........
CO2 is a pollutant.
Humans exhale CO2.
“They” want to eliminate CO2 emissions.
Therefore...
What a study in crowd control, that we can convince most of a planet that carbon can harm us.
According to news this morn when the batteries in electric cars die there is no way to recycle them and they cost $10K to $20K to replace. Gee, sign me up for one.
