so after nearly 700 miles, I'm on an average of 3.4m/kwh. Which is only just below my previous long-term average of 3.5m/kwh which was achieved over the summer and on the pilot sport 4s.

my journeys are mainly short 12 mile commutes or quick lunch trips, always charge to 100%, always have heating and AC on, pretty much always using heated seat/wheel and all journeys are now in the dark.

When we get back to the summer I'd expect the average to start going back up.

Do you know which version that you have?
It looks like there are a couple of different versions of the Michelin Primacy 4 (205/45 R17) I found on the Halfords website, there could be well be more on other websites, all with different Fuel Efficiency/Wet Grip/Noise Level ratings:
  • 88V XL (C/A/B)
  • 88V XL S2 (A/B/A)
  • 88H) XL S2 (A/A/B)

2nd service done today

At just shy of 15,000 miles

Tyres down to 3mm on all 4, reckon I may have another 2-3000 miles wear left in them before hitting the minimum legal depth but will probably change before then. Eeek how are people finding the Primacy e tyres (especially in the wet)?

Discs 10% worn on front 5% worn on rears.

Oh and they changed the air filter, they must have lubed some bushes etc as it sounded quieter on the journey back

I had my 2nd service at just under 17,000 miles on Wednesday & the minimum across the treads of my Pilot sport 4's were:
OSF 4.1mm
NSF 4.1mm
OSR 2.8mm
NSR 2.4mm

Discs:
Front 10% worn (9mm remaining)
Rear 30% worn (7mm remaining)

This is weird being the opposite with how you're seeing your pads wear & is the opposite of every other car that I have ever owned (front, rear or 4WD).

In addition to the air filter, wash and clean inside, mine also needed new front wipers because both were split, which is odd because I had cleaned & checked them on 27/6/2022.

I can't answer how the Primacy e tyres are in the wet, but I've found the PS4's really good and many times I've felt the traction kick in if any slip occurs when I accelerate hard over wet drain covers or on tight junctions with grit/gravel.

Generally the rear pads tend to wear faster than the front if the active cruise control is regularly used. Of course might not be the reason in your case.
As for Primacy e tyres, reading this I would avoid unless rolling resistance is the only concern.

If it had, then I would have been dragging the rear wheels for miles to make it 3 times the wear of the front’s :lol:

On a serious note, I rarely use the auto parking brake because I find that it cuts in too soon when I come to a halt & too late when pulling away which results in jolts in stop start traffic and is extremely annoying.

Until June (when I started working from home) I was always using ACC on my commute so that could be the reason. Now that I’m usually doing shorter trips I rarely use ACC.
Over the 35+ years that I’ve owned cars, on every other single car, the front pads & discs have worn at a rate of around 3 times of the rears.

That report makes logical sense because surely if a tyre has low rolling resistance, ergo it has low braking grip.
