Best Tires for the BMW 330d

First time using 4's, normally have just the sport 4. Very impressed even in the cold and damp, once they have a bit of temperature they are really responsive. Very long life for a uhp.

Positive:
The tires work well on wet and dry roads, they offer enough traction to not spin the wheels even under strong acceleration.
In the corners they offer good grip, you can clearly feel the car starting to understeer when getting to the grip limit in corners, there is no sudden loss of traction or snap-oversteer.
The tires seems to wear slowly and evenly.

Neutral:
Snow traction, mainly on a few cm of fresh snow and snow slush, seems good, but is also limited by the car being rear-wheel-drive without a locking differential.

Negative:
With the tires being the Runflat "Driveguard" variant, the ride can be harsh and the noiselevels are subjectively high. There is a loud humming sound between roughly 80 and 90 kmh (50-55 mph) which can be quite annoying. The noise is most noticable at city speeds, on the highway at over 100 kmh (60mph) the noise starts to reduce and is not intrusive anymore.

Excellent tires.
Fronts 225/49/R19
Rears 255/35/R19.
Fitted to my 2028 BMW 330d xdrive msport shadow edition.
Fantastic tire, swapped over from run flat Bridgestone Potenza.
I've driven on Goodyear-Pirelli-Bridgestone and these have been the best yet.
Would definitely recommend these Cross climate 3 sport for all year rubber.
Excellent tire.

After 20.000kms the rears are around 4mm tread depth while the fronts are around 6mm, my g21 330d is quite torquey and heavy car so i didnt expect too much in terms of wear, but i still expected atleast 40.000kms considering i dont really push the car too much, i will maybe get another 10-15k on them and overall the tires have been ok, wet grip and stability has been really impressive, altho the tires were used in the summer mostly, a bit dissapointed with the noise considering how soft the sidewalls are, previous tires were bridgestone turanza t6 and those were extremely quiet.
Overall im slightly dissapointed in wear and noise considering these are really expensive premium brand tires that are more touring biased.
Will definately opt for similar tire next time just something that has better noise and wear.

Got these tires for my g21 330d 18inch size 225 front 255 rear, previous tires were bridgestone turanza 6 all 4 225 and PC7 is definately louder, nothing excessive its just that turanza 6 was really quiet, every other thing performance dry/wet/ braking dry/wet has also improved, especially in the wet.
Not much to say other than im very pleased, but considering these are one of the most expensive tires you can buy, its to be expected.
Cant say much about wear so far they look like new, i've had PC6 in the past on my leon FR and they were bald in 10k miles. UPDATE: Nearly a year later and roughly 24,000kms done on these tires, the rears are down to about 4mm , wet grip has really decreased significantly and the tires are even noisier then they were already when new, i am a bit dissapointed with noise primarily considering its a quiet car and how silent the previous t006 were, gotta say for the price i paid ( 800 euro all 4) i would not buy them again, i predict the rears will need replacing at around 30,000km mark, the fronts are still holding up ok at around 6mm thread depth.

Due to the odd/rare size of the rear tires fitted to my car (a 2010 330d), their was only a choice of 2 decent tires, these and the even older Goodyear Asymmetric 2s.
Compared to the A2's I had before the PS4 is a revelation in the wet, the grip in the wet was absolutely staggering (above 7C, below which any summer tire will increasingly struggle), it felt like it almost matched the A2s grip in the dry! Truly amazing grip in the wet!
Grip in the dry seemed good too, although I never pushed them cornering.

A big downside though was the rate they wore at, I nearly got caught out hitting the legal wear limit (1.6mm), I usually change tires at 2.5mm.
Although this was partly due to my mileage shooting up that year (due to a job change), it was also down to how quickly the tires were wearing, from new to ~1.6mm (for the NSR, OSR was ~2.7mm) in about 13.2 k miles. Whereas the last set of GY A2s lasted ~18.6k (rears again).

Their is the mitigating circumstance that I found the rear tracking was out shortly after replacing them, by how much I don't know because the garage's printer wasn't working and they didn't bother to take a photo of it either! That said, it was tracking straight and the outer and inner edges and groves had worn similarly, although the rear was tramlining somewhat (which reduced quite a bit after having it tracked).
Also it seems that the factory pressures are too high for the rears making them wear more in the middle, see their final tread depths below (for each main groove) and make your own mind up. But certainly the A2s pumped up to the same pressures and likely the rear tracking had been a bit out for years as the rear tramlining issue (mainly on the concrete bit of the south part of the M25!) had also been around for years!
NSR 3.2, 2.4, 1.6, 2.7
OSR 3.5, 2.7, 2.7, 3.5

Since then I've fitted Goodyear Asymmetric 6s (I had to downsize slightly to 245/40 17 to get them), and actually their not faring much better :(, they've covered 12.6k miles and are down to 3mm in the ctr grooves already (I can't recall what the outer's were, but theirs a smaller difference than the PS4s, which is at least partly down to the slightly lower pressure I use now, 2.5 Bar vs 2.7, not to mention the tracking being done at the beginning of their life).

Absolutely the best tires I have ever had. Yes, they are expensive but you do get what you pay for. This is my second set on the fronts which the previous ones had covered 30K miles and somehow they seem quieter than the set before. Not sure why or whether there has been an upgrade or they are simply new.

The rears still have some life in them but I will be changing these later in the year.

Little tip, ensure your tracking is setup correctly. Makes all the difference in the wear.

In conclusion, you won't be disappointed in the Michelins. Enjoy and drive safely.
