So guys, the Tourer has just gone in for the H&R lowering springs being fitted, and I've just finished cleaning the genuine 437M's I picked up last night at stupid o'Clock for an absolute bargain, the car is a 2017 335XD F31, I've done as much research as I can, and I can gather the following!

Recommended tyre sizes to be within the recommended 1% RC limit will be as follows;

235/40/19 FRONT 19x9J
265/35/19 REAR 19x10J

Tyres will be non RFT, and likely Michelin PS4S, quotes around £750 fitted!

Is there anyone else running this wheel on a F31 Xdrive, and if so what are you tyre choices/experience?

I ran standard size MPS4’s on mine. No Xdrive issues, fronts poked out a little and rears were a little stretched. I wanted to try 235/265 but no one else was doing it at the time and couldn’t risk the cost of getting it wrong.

Just about to put them up for sale as I sent the car back in January

235/40 & 265/35 is the only sensible option for xDrive cars.

The best for sDrive is 245/35 & 265/35.

You'll be fine with the H&R set up, I have a RWD car with H&R on, and never had any rubbing with my 437m's in the last 2 years that they've been on the car

You should price up the pilot sport 4.
Unless you track your car, you really don't need to go for the 4S.

That’s the sizes I was running on my xdrive 330d,no problems with rubbing or scuffing even with the ACS springs fitted. I was running Uniroyal Rainsports 3 with no problems and great grip in the wet.None of this starred for BMW fit nonsense either.
