On the http://www.vmrwheels.eu/wheels_bmw_audi_vw_v810.html page, I found nice flow-formed model V810 wheels said to be compatible with the F22 (the huge ET value of 57 at the rear assures that). But sitll, my doubt is whether they will only accept the 235/35R19 front, and 255/30R19 rear tires without any rubbing problem, or -

- are they also good to go with the 245/35R19 front and 265/30R19 rear rubber?

This is a very important question for me, as only the latter size offers the sidewall high enough for the Polish B-roads' potholes and general ride comfort!

Anyone in the know?

I have overlaid the original, 235/35R18 tire on 8Jx18 ET52 wheel (stock M235i rear) and the 256/30R19 ite on the 9.5Jx19 ET58 VRM V810 wheel - and here is the comparo; is it viable, guys?

Do we have more than 25 mm free space in the inside of the original rear setup? How to measure this? About the outside poking just 13 mm over stock I'm somehow less concerned - but who knows, perhaps this would be rubbing, too? Please note what it says at the bottom: the strut shown is not coming from any specific vehicle! And I added the V810 wheel picture, too; for blue M235i this color would be perfect - though for my Alpine White I'd go with Anthracite!

Thanks; I got an e-mail from Mario at VRM saying the high ET of 58 for rear has not been tested, so it you could measure this (with the 256/30 or 255/30 tire) it would be great.

Mario recommends much less aggressive sizes for both front and rear, as they were tested and proved working ok; here they are:

Front: 225/40R19 on the 8.5x19 ET45 wheel (with 5 mm spacer)
Rear: 255/35R19 on the 9.5x19 ET45 wheel

At the opposite side of the spectrum the most aggressive sizes would be:

Front: 235/35R19 on the 8.5x19 ET35 wheel
Rear: 265/30R19 on the 9.5x19 ET58 wheel

- but again, Mario strongly advises against such aggressive setup as not yet tested an probably rubbing...

You could also get away with 8.5 ET35/9.5 ET45, however, you wouldn't want to go any larger than a 255 tire in the rear. Even then, you may need to roll the fenders. I would imagine that the ET58 rear with a 265 could cause clearance issues with the inner side close to the suspension.
