These would be used as Summer/Auto-X wheels. If the tire sizes are not optimal please let me know what sizes would be better (I would like to get some of the understeer out of the car using tires with no other changes.)
Also do the BMW TMPS sensors fit these wheels?

245/40/18 is a bit tall for the front, but can fit without rubbing depending on the tire used. Worst case a very minor 3-5mm spacer would be needed if you used and extreme summer tire that runs extra wide. The Z4M uses taller tires then the E90/2 so that fits with much more ease on their cars.
275/35/18 on the rear fits perfectly but will promote more understeer then a 265 would. 275 closer to the same size as the 245/40 setup so visually it will look better (0.2" height difference in sidewall height with 245/265 vs same height on 245/275), but if you want to cut down on understeer, you would benefit from a 265/35/18 rear instead, which keeps the size difference front to rear much closer.
That would be used on the 18x8.5" and 18x9.5" setup.
