Rear Tyre Wear

Note that the blog suggests that a factory-fitted Bridgestone-branded tyre (or Michelin, Goodyear, etc) would not be made of "standard Bridgestone rubber", but rather a softer rubber as specified by the car manufacturer.

I call "bollocks" on that blog. Custom manufactured tyres specific to a car? No way, not unless you're in a Ferrari. When I've bought a replacement tyre "off the shelf" of the same type that came with my car, never noticed any difference.

Every time I've ditched Bridgestones for Michelins or Goodyear, pretty much every aspect attributable to tyres has improved - road noise, softer feel, far better traction and turn in grip.

As Utumno says - no manufacturer would fit Bridgestones to improve the car. Picking Bridgestones will be a decision based on cost and/or reliable availablity.

Conspiracy theory. Ignore.

EVs are angels when it comes to CO2 emissions but devils when it comes to particulate pollution from tyre wear, especially at higher speeds. This is due to being quite a bit heavier than an ICE. All the same, 7500 seems awfully short.

This old chestnut again?

https://www.eea.europa.eu/publications/ ... life-cycle

Using emission factors used in a range of national emission inventories, Timmers and Achten (2016) concluded that BEVs likely produce levels of PM10 and PM2.5 pollution similar to or only slightly lower than those of ICEVs.

The rationale for this is that tyre and road wear and resuspension combined make up around 80 % of PM emissions from Euro 6 petrol and diesel vehicles, and that BEVs tend on average to be heavier than the equivalent ICEVs, causing greater rates of road and tyre wear.

In contrast Hooftman et al. (2016) found that, when using data on real-world exhaust emissions of PM from ICEVs, BEVs emit only around half and one eighth the total amount of local PM10 compared with Euro 6 petrol and diesel vehicles, respectively.

A further consideration is the effect of driving conditions. For example, in stop-start urban driving where speeds are low, brake wear particles can constitute up to 55 % of total PM10 emissions from ICEVs, so regenerative braking by BEVs is likely to provide a large reduction in local PM emissions relative to ICEVs in these conditions (Hooftman et al., 2016).

In contrast, on motorways brake wear particles may account for only 3 % of total PM10 emissions from ICEVs (Hooftman et al., 2016), so the advantage of BEVs over ICEVs is smaller, being based mainly on their having zero exhaust emissions.

Make your own mind up

That's interesting. So no contest in slower, urban environments but reduced benefit on motorways. That's a better situation than I have read before. I don't really drive on local urban roads because I can get everywhere I need to go on a bicycle, so pretty much all my EV journeys involve motorways. And so this is good to hear!

Rear wheel drive with high torque electric motors https://en.wikipedia.org/wiki/Electric_motor and regenerative braking https://en.wikipedia.org/wiki/Regenerative_brake creates more wear of the tires

Also some new BEV drivers like to race away from traffic lights putting even more stress on the tires

So it's you right foot controlling the wear and tear of you tires

BTW my wife had to replace her rear tires after 25k Miles
