Rear Tyre Wear

[Tony 3263]

I took delivery of an ID3 in late February 21, the rear tyres need replacing after 7500 miles , evenly worn.
Has anyone else had the same experience?
Not much joy from the dealership or VW technical services.
Thanks

There have been others that have experienced tyre wear issues. Some have put it down to the tyres being over inflated at delivery.

What's the tread depth? Some dealers try to coerce you to replace at 3mm, the Bridgestones only come with 5.9mm tread instead of the usual 7.4mm or 8mm.

What brand were the tyres, some compounds are hugely softer (Continental are probably the worst of the big brands for this).

Don't forget that ID3 is RWD. Even so, I'd expect at least 15k miles from the tyres on the driven wheels.

Lost count of the number of 'discussions' I have had with VW Experts over tyre wear percentages... Also remember the rears are going to be responsible for far greater proportion of the braking (regen braking) in an ID.3 so I think rear tyre wear will be high potentially.

Not banking on getting more than 8k from the rears but if my experience of our BMW i3 unfolds with the ID3 8k will be best case. I thinks it’s just the nature of physics and current tyre tech: a very heavy car with a constant torque curve and regen breaking all through the rear.

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.

If I only get 7500 miles from a set of rears, My ID3 will cost me more for running costs in tyre wear than electricity on Octopus GO..

I've stumbled across this 10-year-old blog post about ICE car tyres:

Why New Car Tires Wear Out So Fast
http://oncars.blogspot.com/2011/11/why- ... -fast.html

Some extracts:

The tires that came with your last new car were [...] made to the specifications set by your car manufacturer.
[...] they will wear out much sooner than they should. This is because virtually all auto manufacturers specify very soft rubber which means they wear out too fast. Why would the manufacturer do that? They want that new car to have the smoothest ride possible, even at your expense of having to buy a new set of tires at half the mileage you should have to. When you test drive that brand new car and it rides very, very smoothly you’re more likely to buy it. You’ll find out how fast the tires wear out much later, and when you do you’ll blame it on the tire maker.

Could this be true at all, and for the ID.3 in particular? No idea, but it sounds plausible to me.

[Utumno]

By that “logic”, no manufacturer would ever fit Bridgestone.

Yet, here we are.

[shire-dweller]

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.

[monkeyhanger]

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.

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
