What makes EV tires different, and why should you fit them.

 

(ignore the constant talk of range concerns by the petrol head)

 

I found it interesting there's so much difference differences between the tyres of same made and model (difference of EV vs regular).

Very interesting as these are the exact tyres my ID.4 came with. 

 

And he's talking *******s about recharge time in that Audi, it's one of the fastest out there.

E-Tron charging times are nothing special when you have just a 50kWh charger available. 

It is actually much a muchness as the charging speed of any other EV on a CCS 50 kWh charger.

I am aware of that!  

 

 

EDIT: Audi E-tron 55 charging curve.

I have yet to hear an Audi EV driver say when i ask that they are unhappy with their Audi.

The only comment i hear is how poor the charging network is in Scotland and how few real Rapid Chargers there are. 

 

That could be changing though. 

Then this winter there might be more of them fitting All Weather tyres.

I wonder if he had his units right when he stated Audi require 30K miles from front tyres and 35K miles from rears? That seems very high. Also, with most EV being RWD (or AWD with rear bias) I would have thought the rears will wear quicker due to the heavy accelerative and regen forces involved. 

I'll be happy if I get 20K out of my rears.

?

Are most EV's RWD or AWD with rear bias?

In the UK the numbers of RWD EV's will be mostly made up of Tesla or RWD BMW i3's & latterly JLR that might have racked up high miles.

 

The Majority of EV's in the UK or even Globally & on the roads racking up miles / km are surely Front Wheel Drive, so Leaf, Zoe, Niro / Soul,  Ioniqs / Kona etc. 

 

The AWD & RWD ones are not yet in the majority are them. 

JLR, Audi, Tesla, BMW & now the latest from rest of VW Group / Hyundai / Kia etc.

Yeah, I'd be very happy if I can get 30k out of any tyre. Even the expensive Micheline CC+ on my Skoda is now down to 4mm after 16k. (rear are still 7mm though) 

 

But Hankook are known for lasting higher mileage among mid-range brand. So I think their EV tyres are worth a shot. 

Question for manufacturers and importers of EV,s to the UK.   Why are they not all being delivered with EV specific tyres?   Why are some just coming with Suitable ECO tyres that can eek out range but are not performing well as All Season / All weather / all year round if you use all around the UK?       Many will have tyres that might not require changing within the lease period so before handed back at 2 or 3 years.  Lease / fleet / Motability etc will know how many miles as an average  EV,s they own are getting out of a pair of set if tyres.  So will the Tyre industry / tyre centre companies and so should the AA / RAC and SMMT.

One must presume the volumes are low and they use what they can and is readily available when they do the PDI which is done sometimes partially at the docks where the come in and at the dealers when a clients might spec larger wheels.  One would hope and EV driver spec smaller more efficient winter wheels and even narrower ones again for winter to help get as many miles as possible.

 

I change my tyres at 2 to 3 mm not 1.6 mm as do the cops.

 

Where is a good source of EV tyres as Tyreleader do not look like they specialise in EV tyres or they are difficult to find on the site as there is no filter for EV tyres ? 

 

@lol-lol

The issue with 'Centres for PDI / Optional extras and then distribution' is.

 

The Transit Blocks should not be removed, or the tyre deflated from the factory pressure before the car left the factory if it is then going on a Transporter to the Dealership or Click & Collect collection anyplace around the UK.

 

If the car is being driven by a delivery driver then the Blocks should be removed and the tyres set at a safe pressure.

But then the car will no longer be set in 'In transit mode and the mileage should be at zero again' from it being First Registered or being moved on Trade Plates.

 

PS

For a while i worked in a major manufacturers premises in Scotland where vehicles came all the way north and were prepped including Body Styling options fitted and even Leather Interiors fitted so cars were to the UK spec.

They had fluids in, a limited amount of fuel and were well protected and wrapped and then were prepped to go to Dealerships.

The Transit Blocks were left fitted, or fitted if the Springs were changed, and the tyres were left over inflated so there was still PDI actions required when the cars got to Dealerships.

There should be more Articles & Vids like this coming.

Hopefully covering Summer / All Season tyres & All Weather or Winter EV tyres.

Looks like the Michelin Energy EV are the ones for the Zoe unless one opts for the 17 inch rims which loss the car a few miles in range according to Renault's old range calculator... 

 

Sounds like a good idea to hold some personal stock of these tyres as well as maybe a set of 15 inch winter tyres.   

 

@lol-lol

I was going to post this earlier but Briskoda was down.

Michelin do make crap tyres sometimes.  I think there are some rubbish Primacy 4's about, more to do with range rather than grip / traction / safety.

 

2019.

 

2012.

Interesting.  also that 40 PSI si the stated recommended pressure for the tyres, do think I have ever run fronts that high.  Be interesting to see what the Renault garage set it to when I pick it p.

 

The salesman runs a R135 hp Zoe to and travels from Birmingham to Worcester each day so will ask him what he runs on tyre pressures.

 

Never use Primacy as did not like the write ups.  

 

The tearing in the first video looks so bad I would have stopped using those tyres and that is on an old Zoe with less Torque etc it would be.

 

Time moves on and maybe they have got a bit better since the video, I will do some research on the specialist forums.

 

PSA so now Stellantis and Kia /Hyundai put lots of EV;s out on Michelin Primacy 4, far too many really.

Not "EV" marked tyres on the Zoe I picked up yesterday.

 

The Usual Primacy 4s in Heavy Duty/Load spec.

 

All 4 tyres set to 36 PSI by the dealer so I corrected those fronts to 38 PSI to help prevent torque ripping and outer edge wear that is associated with the lower tyre pressures.

 

Left the rears at 36 rather than drop to 33 psi as the sticker states.

 

No advised tyre pressure for when one is carrying several people plus luggage, again a bit odd, hence 36 seems OK or maybe even 38 in the back tyres too if the ride is not too firm.

 

Some more miles today and continue to think about some winters maybe in the 15" size 185 width, not sure whether they will be All Seasons or full winters, probably All Seasons, keep those nice Diamond cut OE rims in pristine condition. 

 

On Thursday I upped the tyre pressures on my Michelin Alpin 6 from the 34psi I have had them at since last November and instantly could see that made a difference of energy use. Around town 3.1 miles kWh before increase was up to 3.6 having driven just a couple of miles.  Done 300 miles since and easily that slight increase in pressure has been helping get a bit more range.

16 inch Alpine or 15 inch?

 

I was getting near 4 miles per kWh but then decided to do my first full power test up a dual.carriageway hill and 84 mph came up quickly, not as quick as the 150 hp octy but quicker than the 90 up Clio or Davis despite it's 1600 kg running weight.

 

I see the cash still saying full regen is not available as battery full, battery says 95 % full after 18 miles.

 

I am suspecting one can charge the battery to about 102 % of nominal but it shows 100% for six miles rather than dropping 1% per two miles as I expect.

 

I top to 100% just when heating the interior (when plugged in to 3 pin at home, topping up from arriving from public charger with 98% in)

but really 98- 99% is fine as no regen for a few miles after setting off is not always good and setting off with regen available can get you just as far as setting off @ 100% and needing to use the brakes.  I seldom go to 100% at a public charger, just to 99 on a DC, of on a AC it is sometimes at 100% before i notice.

It does give the brake discs a bit of a clean off when setting off at 100% though so useful that way. My discs are a mess as hardly ever used.

 

*The Media cars that were available to test drive were on Michelin Pilot Sport, i drove a e-208 & en e-Corsa on those, 

and they were a nicer tyre for summer, then the cars came on Primacy 4 that were nothing like as good for the handling or grip.*

 

I had put CrossClimate + 205/45 R 17's on as soon as i got the car and had driven on wet roads, but after the snow arrived i fitted the Alpin 6 in the OEM size.

Higher load / speed rating are on the front as there were just 2 of each available.

They have been great winter, wet weather and totally fine when scorchio.

 

I never bothered to put the CrossClimates back on as they will be used sometime on something.

The Primacy 4 will go back on when the car is handed back and will only have done a few hundred miles.

Just tried to charge with my 3 pin charger from 95% but it did not a want to know with the charger box saying car was already full.

 

Just keen to check lead is working.  Have to go do some more miles and try again.

 

Should find a public charger and try to charge there, Asda maybe.

Any car i have had home might get plugged in and charged to 100% and then left to cut off and charge while parked as the battery level drops in the cold, and then i start the heating via APP to heat the car and de-ice the windows.

Or i go out and switch the car on and turn up the heating and open the windows a couple of mm.

 

I just have an extension lead, waterproof boxes, and never bother setting timers as i am not on a smart meter or a tariff with Off Peak.

I came away from Octopus as the Gas tariff was too high.

No idea who i will get as my new provider as even the Daily Standing Charges are unbelievable compared to the 12 month deal i got with Eon.

I think I need to check what my voltage is to the charge box, I was just thinking that plugging one extension in to another, one a couple of meters and then another 15 metres and then plugging in the meaty wired 3 pin charger with its much thicker wiring.

 

It cannot be good to attach 13A and even 10A extension leads and then plug in the car charging 5 metre lead.

 

I would hate to think I am only getting 220 volts

 

https://www.spenergynetworks.co.uk/pages/voltage_changes.aspx

Manufacturers usually allow a further margin of safety and, if the voltage does occasionally fall outside these limits, there should be no adverse effect on your appliances. In the UK, the declared voltage and tolerance for an electricity supply is 230 volts -6%, +10%. This gives an allowed voltage range of 216.2 volts to 253.0 volts.

I have learnt something new today !!!!!

 

https://www.leadsdirect.co.uk/knowledge-base/what-is-the-difference-between-uk-voltage-and-european-voltage/

What is the difference between UK voltage and European voltage

The voltage used throughout Europe (including the UK) has been harmonised since January 2003 at a nominal 230v 50 Hz (formerly 240V in UK, 220V in the rest of Europe) but this does not mean there has been a real change in the supply.

Instead, the new “harmonised voltage limits” in most of Europe (the former 220V nominal countries) are now:

230V -10% +6% (i.e. 207.0 V-243.8 V)

In the UK (former 240V nominal) they are:

230V -6% +10% (i.e. 216.2 V – 253.0 V)

This effectively means there is no real change of supply voltage, only a change in the “label”, with no incentive for electricity supply companies to actually change the supply voltage.

To cope with both sets of limits all modern equipment will therefore be able to accept 230V +/-10% i.e. 207-253V.
