As for Primacy e tyres, reading this I would avoid unless rolling resistance is the only concern.

The stock PS4's take some beating
Cheers for that, I was suspicious on how they managed to rewrite physics, it seems they didn't :lol: had some Bridgestone B340's originally on my smart Roadster, we called them Flintstones, shocking in the wet and some people managed to get 80,000 miles out of the fronts!

Think I'll stick to the pilot sport 4's as I haven't gone off the road yet with them, even with my driving :P

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.
Yes, in the past the front pads would always wear considerably faster than the rears, however in todays era of technology, my understanding is that the rears are predominately used by ACC to reduce the speed when following the car in front, hence the increased wear.

Just replaced my fronts.

Rears around 18000 miles and now the fronts at 20,500 miles.

Not exactly brilliant wear, maybe I need drive a little more sedately 😁

I replaced yesterday all my Pilot Sport 4 for the first time after 50000km.
The rear wear were not so bad but the fronts were in a disaster state. Peeling off.....

I chose the Primacy e and I already noticed the efficiency. I need less power for the car to move forward and need more braking to stop. In fact the first day for my daily commute of 26km round trip, from the usual 12.5 kWh/100km went down to 10.1 kWh/100km. That is like 20% gain. Very impressed.

I used to keep the pressure around 35psi but now I went to 40psi with the new ones as I had wear on the sides very bad. So that might have helped too.

Wow, can I assume you are on 17?

For your new set, what load rating are those in?

Wow! That's over 31,000 miles, I've not reached 20,000 miles (32,000km) and mine are very close to the minimum wear indicators.
You must drive like a nun :lol:

Hehe, well yes here is only city driving and traffic all the time, that's why also the reason for my low consumption. I am very gentle on both pedals. I think the rears could have done another 10000km

Guess it might be that's why they list it as ZR for the 17s in the manual.

Thanks for sharing, makes me even more committed to look for 16 in steel to try bring the efficiency to yet another level.

Reducing weight of rims, width of tyres, roll resistance of tyre and weight for front brake disc by changing to floating disc with aluminum hub are on my mind.

I’ve missed the reason of ZR, please can you explain this to me?
