Pump up your tyres!

[CCMG]

I just pumped up the tyres on my MG ZS EV LR. They wern't low enough to trigger any warning, they were at 2.6-2.7 bar. But pumping them up to just above the recomended 41 psi (2.8-2.9 bar) has noticably increased the efficiency on the same journey at the same time of day/bad weather from 3.3ish mi/kWh to 3.6ish mi/kWh.
It's worth checking them every so often as it really does make a difference to efficiency.

I have the same model. I was surprised that my tire pressure was with higher reading of 3.2 and 3.1 when I collect my brand new car last year. I have not pumped at all for 4k miles driving in 12 months. I just have reading of 2.6, just like yours. I thought annual service will help but it seems dealer did not do anything.

I pumped mine up to 3.2 bar

Lower is more comfort

Higher is more efficiëncy

 

[profdraper]

Of course, I've always followed the recomenndations that are written on the inside of the driver;s door on any car. ZSEV: 2.8bar /41psi, a no brainer,no problems.

Although inflating the tyre pressures may improve the efficiency slightly, this can make the ride feel very choppy and uncomfortable.
Also it has the tendency to produce uneven tyre wear in the centre of the tyres.
The contact surface between the tyre and the road is naturally reduced.
This condition will affect traction from the driving wheels and also increase the cars stoping distances.
Especially in wet driving conditions.
Under inflated tyre pressures throw up a different set of concerns and problems.

2.3 bar is recommended for zs ev ?

2.3 bar is recommended for zs ev ?

Please check the pressures given on the driver's door pillar. 2.3 bar for the mk1, 2.8 bar for the mk2.

Now you pumped them up that far you grip will have gone and the middles will ware out rapidly as that's all that will be touching the road. I have mine at 2.3 bar which improves grip and handling and they last 40k miles without issue and ware is even and I get the same m/pwh on my 44kwh MK1 unit. I don't know why they say they need to be higher on the MK2 but I do know the default tyres on the MK2 are not great.

You need to be a little careful running 20% lower pressure than the manufacturer recommends. In the event of a serious accident the insurance company could suggest running lower pressures could have contributed to the accident.

It's not high. It's what's recommended. So no issue with grip or wear.

Mk1 and mk2 have different recommended pressures
The mk2 is at 41psi. If you have a Mk1 then it's lower as I assume it has got different tyres.

You should be running the pressure the tyre company recommends for your car as such am not under pressure at all am over pressure as it says take -2 psi for summer. In my case am running quality tyres Michelin Primacy 4 will be e.Primacy in 5k miles not the cheap and nasty maxxis that's on the mk2 I have had maxxis tyres in the past on other cars and they are shockingly poor in the wet and ware horrible they come up as cracking on the 1st mot and I seen plenty of people switch them out back to Primacy 4 for a mk2

 

[Lovemyev]

Having had a two year secondment at a car assembly plant many years ago, I found that the manufacture of the car, will install what ever make of suitable tyre, that are able to secure a really good deal on at that point of time.
Huge batches of say Good Years, used for months on end, to be suddenly switched out for say Bridgestones etc.
They hold no loyalty to any one tyre manufacturer TBH.
This action can be clearly seen on the Gen2 ZS EV model, as the initial batch of cars came through with the Mich Primary that we have on our car, then they switched over to fitting the Maxxis for a while.
Bulk buying at its best !.
Bridgestones are a hard compound tyre and produce a lot of road noise, together with poor traction when pulling away.
Not on my list of favourite tyres TBH.

 

[MJ21]

I pumped mine up to 3.2 bar

That is too much! You will blow it.

 

[DB Go Rex]

That is too much! You will blow it.

That's how my car came delivered when it was new.

The tyre pressures (Maxxis Bravo HP-M3 215/55R17) when we picked up our 23 MG ZS EV Essence from the dealer in 2/25 was 3.3 Bar. I assumed this was the correct pressure. More fool me.

Today and 1700km later the pressure is down to 3.0 Bar. Cooler weather in Melbourne may be contributing to the apparent 10% reduction in tyre pressure on all tyres.

Going forward and as others have noted, inside the driver’s door the recommended tyre pressure is 41psi (2.8-2.9 Bar). Maxxis recommended maximum tyre pressure is 44 psi (3.0-3.1 Bar).

Going forward, any advice about which tyre pressure to use is welcome. Use of the car is 50/50 metropolitan/country driving with one or two adults and overnight bags on country trips.

I got my car in January and they were set to 2.9 to 3 bar. But the handbook is clear it should be 2.8 bar. But at 2.9 - 3 bar the MG ismart app says they are normal.
Tyre Pressure (Cold)
Wheels Unladen
Front Wheels 280kPa/2.8bar/41psi
Rear Wheels 280kPa/2.8bar/41psi

Why not just stick to the manufacturer's recommendations, surely they know better than any of us?
