tire fitments for e46 m3

[hockey21]

So, the 19 comp. wheels are 245/35/19 and 245/35/19

will 245/45/19 and 245/ 30/19 fit,

can the middle number be varied at all, or would you guys stick with the top choices?

Well, you could I suppose....but 245/30/19 has a 4.59% smaller overall diameter...that equals to 1.2 inches. May look a bit weird...
Your speedo will be off by about 3 mph, if put on the rear.

You need to stay with the 245/35R19 on the front and a 275/30R19 on the rear.
