So tyre manufacturers of all types are now offering their ranges in "EV" specific fitments, but, like V-Power diesel, I'm not buying it.

Weight:
They say: EVs are heavy, so all that weight needs to be supported properly.
I say: Most SUVs weigh over 2T, and still have normal, XL or SUV tyres, Urus for example, RRS, etc

Instant power, vtech yo:
They say: That instant torque will shred a normal tyre to pieces within 5m or 0.5 seconds of accelerating, whichever comes sooner
I say: So these "EV" tyres would start appearing on 911 GT3, Turbo S, Urus etc, where grip is king.

Basically, when the time comes to replace my whatever EV tyre I have on the Enyaq, I'm trying to decide if I really really need to care about being EV specific.
 
Nope. No black magic. As you suggest, like SUV tyres they have heavier, thicker sidewalls. They're also reinforced to deal with the instant torque.

The reason you won't see them on the cars you list is the weight. Even though they're powerful, heavy and have rapid torque application it still isn't instant like an EV. Check out the torque curves if you don't believe me!
 
I went through this when I got mine. however now looking at the tyres on my car, they have done 47000 miles and going on the dates I think they are factory tyres.
given how long they last and they are barely a few quid more than other branded tyres I have decided it doesn't matter I may as well just get them.. my understanding is EV tyres are made with a view to balancing handling with a toughened sidewall whilst also considering range.
yes there is probably marketing bull in there as well and they would be just fine on any SUV I am sure.

Goodyear eagle sport all season for me I think.

Michelin have a lot of spiel about it but ultimately say you can use any of their tyres on an EV.

Their 'EV' tyres have various characteristics desired by manufacturers - stiffer sidewalls to try and hide the weight, better rolling efficiency for increased range etc.

You may find a small reduction in range/efficiency by using a normal tyre, but that's about it. Add an extra couple of psi and you'll get the same effect.

It's an Enyak, not a Plaid.
 
The torque delivery of an EV is a lot kinder than that of an ICE, don't forget that a gearbox acts as a torque multiplier so absent weight issues tyres have an easier time on an EV than an equivalently powerful ICE.

Sound is a factor as well (Dampening, tread pattern arrangement etc)

OP: Just put a tyre on that fits the required specification. If you dont "buy" EV specific claims then dont buy EV specific tyres.

Either you look at the manufacturers claims and other research/reviews or come to your own conclusion. I very much doubt any end users can give any useful feedback from anecdotal sources. The differences in range, noise etc without scientific testing will likely be outside of your/our perception.

The headline figures that you see look high on an EV but because they run a fixed final drive ratio you aren't multiplying the torque actually going to the wheels to the same degree as an ICE would in first and second gear, meaning tyres slip less and wear less than you would expect.

An EV has instant torque and ‘revs’to 15k-20k too so they are still relatively short geared. They kill tyres which is why my cupra born needs new tyres at 15k but my M3 did 25k with twice the power

EV tyres are mainly about efficiency

Errrrrr no?
 
don't see why what he says absolute torque from gearbox multiplier isn't true - 3400NM from M3 in first ... which would suggest any ev additional tyre wear is mainly due to additional weight,
also have the faster/more-efficient ev traction control systems too, to not scrub them as much.

yes the efficiency desire for lower rolling resistance on the ev tyres is another driver with a trade-off vs handling/compliancy - like buying hard michelin eco tyres for my ice, w/ low rolling resistance, poorer handling.

so is an M3 putting down 2000 or 3000Nm for a limited part of speed range better/worse than an ev with a less max torque.
 
310Nm on a 8:1 isn’t far away from a MEB rear motor and that’s pretty average. For more of the speed and from instant too

While I went with pilot sports on my model 3 performance (mainly as I didn't want the foam as punctures can't be repaired), having the tyre walls disintegrate due to power is an interesting thought, although tyres aren't rigid so I'd expect the force to not do any lasting damage. Be an interesting claim against a tyre company if their tyres did fall apart.
Fwiw the car came with kuhmos on and they survived a year without exploding and fairly sure they're a bit of a budget tyre.

I always considered kumho to be an upper midrange tyre.
am sure some who only insist on the most expensive premium tyres would claim they are ditch finders... but I had them on 2 fiat coupes and a nissan 350z and always found them great. I even had one very hairy moment in my 350z where I thought I was in trouble and the tyres massively over performed my expectations (80mph full on panic uncontrolled swerve around a box falling off a lorry). the tyres screamed but the car was amazing - less so my driving skills!.

At least on the SUV type EVs slightly stiffer sidewalls and better rolling efficiency are not insignificant factors. Driving heavier, taller, vehicles with plenty of torque you'll start to really hate tyres with too soft sidewalls if/once you've experience of the difference side by side.

Although it can't touch their 0-60 times, people forget even the old Nissan Leaf can match or beat most performance ICE cars 0-30, unless you have quite fine accelerator control pulling away even "normally" in an EV is more demanding on the tyres.

I always put Kumho on my Corsa VXR as I found them to be a decent balance between performance and price. Didn't ever seem to cause me any issues, sure it's not a 400BHP car (touch under 200) but it's a brand I would go back to.
 
Pirelli have developed special tyres for the BMW iX - Pirelli P Zero Elect, with a focus on low rolling resistance, a revised shape to help aero and it uses Pirelli Noise Cancelling System (PNCS).

NEW PIRELLI P ZERO ELECT TYRES FOR THE ALL-ELECTRIC BMW iX BAVARIAN FLAGSHIP

Milano, 16 March 2022 -- Pirelli will supply P Zero Elect tyres as original equipment to the new BMW iX – a 100% electric SUV from the renowned German car manufacturer – for the xDrive50 version and the more sporty M60. P Zero Elect tires are available for the BMW iX xDrive50 version in...

My Polestar had special Bridgestone tyres with foam inserts to reduce noise too.

see I am a stickler there so I am out. I always insist on round tyres!

;)

one thing I don't get. all the focus on aero for EVs and low rolling resistance. whilst the effect may be more visible in an EV, that is good for all cars really. take the wheels that EVs often have, they can affect the range quite significantly. surely if they were on an ICE car if they give an extra 5 miles out of every 200 for an EV it would give an extra 15 miles out of a 600 mile diesel tank of fuel?

same with tyres.
