Correct Tyre Pressures?

CarbonEV · Monday at 4:13 PM

I have read mixed opinions on Tyre Pressures but wanted to ask what is the recommended / correct values PSi for the XPOWER?

I’ve read that slightly over inflating helps with the Vibration / Electric Hum at higher speeds?

Appreciate anyone’s views on this

I put 38 PSI all round myself

40 psi all round also seems to be a good/popular choice.

I use 262 kilopascals, or 38psi in old money.

Mine were all over the place when I took delivery and I had some vibration above 60mph or so. I equalised them all at 40psi and have had no issues since. It's comfortable enough at that pressure.

Yup, 40 psi minimises my vibes to a level I can deal with.

Circa 2.8 bar if that's what your display reads.

I run 40 psi also.

As above I run mine just under 40 PSI, the display usually shows 274 Kpa I think (or 272).

As well as reducing the vibes it also stops the tyre pressure warning messages on cold mornings (when the pressures have dropped naturally).

Actually I've just checked mine after it was in for it's first service yesterday, and they have put them up to 272kpa (about 39½ psi), so I'll leave them at that.

I run mine at 2.5 bar all round as per the owner's manual, no issues.

It's supposed to be 250kPa all round, but I inflate to 270kPa and find the ride a little smoother and quieter
Onboard pressure sensors are remarkably accurate too, so I always check/reinflate at 10°-20°C which seems to give a good balance between 260kPa and 280kPa on the road depending on outside temperature and tyre temperature.

That's the general consensus, over inflate them slightly, particularly on the X Power.
And the ride/vibes seem to be a lot better.

If you have the 'vibes', maybe. I don't have them and run at 2.5bar as per the owner's manual which gives a nice ride.

I'd been driving a Tesla performance model before that. You want harsh rides, get one of those. I think the MG4 on solid wheels would be a more comfortable ride. Those Tesla's were definitely not designed for UK roads...
