No I didn't lift off, it did sort itself out but the DSC definitely didn't flash up which was a bit odd. We have seen the DSC come on a few times when pulling out of a junction without us booting it that much. It must be these awful tyres! I checked the tyre psi today and it was 30 psi which is way below the 38 psi recommended, but the BMW dealer must have set them at this. Do you think that could have made much difference? |

The MPSS do have continuous water drainage channels to help clear standing water but these can be overwhelmed, just like on other tyres. I've had a couple of moments when the car lifts on motorways when I hit standing water, but I've had the same thing with every other tyre that have been fitted to my cars. Lift-off the throttle, no brakes, steady steering inputs and the car stays stable for that split second until grip is regained. In like for like conditions the MPSS beats the OEM RFTs hands down, and if the conditions permit (weather, location, traffic) the MPSS is a top-end performance option compared to the factory-fit low cost option. Other non-RFT options may have a more balanced design regarding wet/dry performance, but the MPSS are very capable in the wet and outstanding in the dry.

You could put your VIN into an online VIN checker to verify the car's spec.

Now to see where they are cheapest. Btw, did you go with the XL ones for yours as the price seems similar for XL and regular |

I'm not sure the tyres will necessarily change the outcome.
As noted above, xdrive is rear wheel biased so it only really kicks in when the rears start to lose traction. If you left your foot in I think it would sort itself out no problem, but by the sounds of it you're (quite naturally) easing off at the point xdrive would properly kick in. No doubt the tyres will help a bit, but if you're unloading maximum power in the wet coming off a roundabout I doubt many tyres will retain perfect traction xdrive or otherwise. That said, I've got an s-drive so what would I know! |

How much do you want for these tyres? Are these ok if the pressure was low?, any punctures? PM me, pls

The Bridgestones are far from the best tyres in the world. However, they do their job adequately for most situations.
I have a 330d sDrive and rarely find I un-stick the back, under 'normal' driving conditions. The only times I've had any unexpected back end movement have been when pressing on in comfort mode and the gearbox gets caught out by a request for power and downshifts out of a corner/roundabout. If you want to drive rapidly or sharply, I'd suggest the use of the sports setting for the gearbox, or entire car. The downshifts are much more predictable and you don't get that unexpected downshift and then suddenly all 550Nm at once. Also, the big torque diesels seem to respond much better to a progressive/analog right foot rather than a sharp/digital one.

Yes you're right about having to be careful about the car downshifting during a corner as this can obviously destabilise the car so I will experiment with using the sport mode more when going for it in the corners. Many Thanks, Adam |

The old fashioned mechanical 4WD is much better in real world scenarios, where our cars would cut power (which is absolutely horrible in 75% of situations) the subaru doesn't (can set it to locked or open), and you can throttle out of such situations. |

If you are going to change the tyres then change to the best (michelin pilot super sports) then go lower grade after. I found that on my old E92 N54 with Birds suspension kit and MPSS it was a great. It just grips and grips in the dry, but on the wet is not as good but much better than runflats

The fronts are 225's and the rears 255's, save your money and get the f1's you've had them before and know they work. The rears will be available later this month. From what you've said about your driving style the MPSS may be overkill.

Indeed. Which is why I drive my SDrive in Sport+ most of the time... I really don't want the power cut when I am getting squirrelly.... I want to throttle steer please and bring it back in line when I am good and ready. But I guess BMW have to aim their cars at the majority of modern drivers who are more used to underpowered, understeering FWD's rather than tail happy RWD 80's machinery. |

I cant say I’ve had any issues with traction in the wet on a straight line in my 335d. Flooring it in a straight line does not bring on the TC light, even with crap run flats.
I can only assume the OP came across some oil in the road to cause this or maybe the slightly more aggressive nature of the 330d’s power delivery caused it?

Still got my Scoob, 2004 WRX 5 door with the Prodrive Performance Pack so it's about 275bhp.
It's odd, It seems faster but miles more twitchy than the Beemer. Definitely more fun but I'm turning into an old git and I love the comfort, speed and sure footedness of the Beemer. I can get the Scoob slipping and sliding in the wet but the 335 just seems planted and I haven't had any real moments of drama in the last 11 months of ownership.

Only the Type R I could describe as twitchy in any way, and only when right on the edge.
