Best Tires for the BMW 330D Touring

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.

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.

After watching a review on YouTube comparing 3 premium tires I went for the pilot 4s. Instantly transformed the ride quality and reduced road noise I had from mid range run flats. Fantastic feedback turning into corners. Sticks to the road like sh*t to a blanket. Really happy with my purchase. Haven't yet tried them in the wet as they are only on the car a few days but for my driving style they are superb.

Extremely happy with these tires. Fronts are 225/40/18 rears are 255/35/18. 330d xDrive.
I bought and fitted them a bit earlier than I usually do (mid March). As luck had it we had a few rainy and very cold days with damp and almost 0C temperatures in the mornings, when going to work. While they of course required careful driving I was surprised by the amount of grip and confidence I had in those conditions.
Now that temperatures are higher and it's mostly dry I can say I am even more impressed. Grip is outstanding, they are noticeably quieter than my previous tires (Hankook evo 3s) and the ride is quite comfortable. I can't comment on wear as I've done about 1200 miles so far.

I replaced the previous set of Michelin Primacy 3 runflats with these Protech Newgens from Continental's budget brand; formerly Norwegian made but my tires were made in Portugal. The price offered from Delticom for this recently updated tire design was so low that it even undercut some of the chinese brands- I had to try them. I think these tires are identical to the Gislaved Ultraspeed 2, at least the tire pattern is the same, also Conti-owned. As for my experience with the Vikings driving wise, they have been absolutely adequate -but one can tell they are not a premium offer -quite noisy for an standard non runflat tire and the grip is fine to a certain degree, then it vanishes rather quickly. But the fantastic upside is treadlife: driving a RWD BMW 330d Touring with 258hp and 560 Nm one is used to the car wearing out (especially rear) tires quickly, but these have lasted for 3.5 years so far, with plenty of tread depth left - and that is AMAZING.

Bought the tires at the start of this winter season (2023). Fronts are 225/40/R18 rears 255/35/R18. We didn't get too much snow or cold temperatures but still managed to test them on a mountain road with a fair bit of snow which by the end of the day had been blown away and left a thin layer of ice. Tires performed superbly. Car is xDrive which certainly helped going uphill but handling and grip downhill were still very predictable. Noise is decent, our road surfaces are poor but compared to other tires they do seem to generate more road noise but nothing bothersome.
For a winter tire road feedback and feel is very good, the best I've ever felt. Cannot comment on wear yet as I've only put about 5000km on them so far. But thread is barely worn so I expect they will have a pretty good life.
Only downside is that after ~3000km the car developed a very slight vibration when cruising at above 120kph and a very noticeable shudder under braking from the same speeds and it was fixed by balancing all four tires again. Have never had such behavior before with any car. But a simple balance took care of it and I have had other tires need a second balancing after some initial break in. Overall extremely happy with the tires. Recommend them to anyone that wants a sporty tire with amazing snow performance.

I had these fitted based of the reviews they received and they weren’t exaggerating, the grip is just endless on them, I can finally make use of the 700nm on the rear end without the traction control light flickering, these things once they have a bit of heat in them are like glue to the road. Give them chance, the initial 200miles were worrying but once they’d scrubbed the shipping layer off they are a different beast. From a price point of view they are a big chunk cheaper than PS4’s and yes they really are better than PS4s as my other car has them. Best value best grip tire out there hands down

The tires had good grip the first summer then they were stored well and the next summer the grip dropped a lot. Now they are worse than economy tires.

I had a full set of these with some replica BMW M2 competition alloys as they were cheap. Can honestly say these have been impressive given the cost. Have done approx 21k miles on these, the Fronts are only about 50% worn, the rears about 70% but given the geometry of the rear the insides are wearing quicker but still doing well given the 320bhp/700nm going through them!
