Hey guys, on the 525i I ordered, I am going to go with BBS CK's in 20x8.5 f, 20x9.5 r. Tire rack says that the reccomended tire size for the front is 245/30, and rear is 295/25. I was thinking I would go with 245/35 up front and 275/30 in back. I have checked all the threads regarding the tire sizes for twenties and have come up with a 1000 different answers! So are these tires sidewalls too tall for the rolling diameter? Also what is the advantage with going with staggered? Any help from BBS owners would be great!

245/35/20 275/30/20 is correct. They recommend that size because it is smaller in height which is "better" for your odometer. It doesnt matter, 245/35 isnt gonna hurt and in fact its more safer for your rim. 30 in the front will cause a bend much faster.

Which CKs are you getting? Silver?

From looking at the various specs, it looks to me like the 255/30 might be the best way to go in the front (in terms of closeness to the OE size). Although it is a 30 aspect ratio, the 255 width should counteract that. I guess they're recommending the 245 bacuase ofthe 8.5 front; the screen usually recommends the 255/30 on 9 front wheels. I'm sure either is fine.

But when you go 255/30 your most likely going to go 295/25. One wrong move and its game over on that 25 series..
