Good point, the torque was unchanged, but power was reduced to 161hp, and the gears were more widely spaced, it still seemed fast to me, I was used to driving a Ford Focus!
The tyres seemed to last for ever on the 320ED, it will be disappointing if I can’t get at least 20k miles in the 330e.

As a matter of interest, what sort of pressures are you keeping tyres at? Seems to be general consensus that door jamb sticker values are too high at 2.7bar. (which also suggests increasing even further to 3 and above for "ECO")

I have same size tyres and after only about 700 miles they are around 7mm. (nowhere near your 3500). Sticker on door says 2.7 front and rear, idrive reporting 2.6 all round with 2 7 as recommended.

Plate on door for light load 39psi/2.7bar. My screen shows 38psi

Here's the wear (same on both rears) after the 11,500 miles.......

I'm a bit late to the party here but I have the same tyres on the 330i G20, generally driving in comfort mode, and my front tyres wore out in the middle like yours after 19,000kms. I can't remember if I had my tyres rotated about a year ago (back to front, I think I might have). Point is, I don't check my tyre pressure as often as I should so over inflation is just about impossible for me, and yes they still wore out in the middle (just validating what you've said).

Also coming to the party late. 330e G20 with Bridgestones on the front and rear (Front 225/40 19 and Rear 255/35 19). 22K on the clock and ALL the tyres are now completely worn down the middle. Running at PSI 2.2 which I would say is under deflated if anything.
4 years life for 22K miles not bad. No idea how the car was driven for the first 11K miles but since then it's been all electric driving and pretty pedestrian

I know it's reviving this thread but having just recently done a 'smart repair' on one of my alloys it gave me the chance to check the tread depth accurately on the tyres. All evenly worn between 5 and 5.5mm uniformly across the tread width after having covered 14k miles and have always inflated at 39psi at 'cold pressure setting' throughout their lifetime. Pirelli P Zero PZ4 runflats.
