Need some help deciding on a winter wheel & Tire setup. I have a 435 xdrive and it is lowered on KW V1 Coilovers, with the m perf brakes (370mm discs). I think the biggest challenge for me will be the 18 wheel fitment over my brakes; it is hit or miss depending on the wheel.

If I can get a wheel to test fit, I may go with these because they are so cheap:https://www.discounttire.com/buy-wheels/drag-dr-67


If this doesn't pan out, does anyone have a good recommendation for about $150 a wheel? Maybe I should just get a second set of 19s? Look for a sued set of OEM wheels or reps that fit over the brake?

I would like to run a squared setup with either 235s or 245s assuming I can fit the 245.

Are the yellow M Performance brakes larger than the blue M Sports? If not, Tire Rack has a few 18" wheels which they say will fit over the blue M Sports for around $150 each. This is the direction I'm looking at going for my 435 with the Track Package.

supposedly all oem 18" will fit over M-performance brakes. i'd get a used square set of 18x8 397, 400m. 225/45/18 or 235/45/18 square. nokian hakkapeliitta r2(1st choice) or bridgestone blizzak ws90 or michelin x ice xi3

Tires too small trying to fit 255 but will settle at 245. I know smaller is better in snow but its only a few times i actually drive over it.

245/40/18 will fit and is the widest that can go on 18x8

i'll see if i can find a decent 18x8.5" +35ish wheel for $150 if you desire 255/40/18. for winter/snow tires, as you go wider the price goes up and selection gets more limited, though

255/40/18 +35 should fit without issue even if you are lowered.

Actually the blue front calipers come in two flavors, for either 340mm or 370mm rotors. They appear identical but are not. Casting on 370's is 15mm longer. There is raised lettering on the back of the caliper that either says "340" or "370/380". See photos.

The front blue 370 M Sport calipers are identical to the M Performance calipers that come in red, orange or yellow. The rear calipers are identical no matter which of the four colors and are over 345mm x 24mm rotors
