Tire Diameter question

[Shardul]

I have a 2001 E39 with the factory 17 bbs rims with 235/45/17 tires on them. I wanted to upgrade to a 19 inch wheel and tire package. what size tires should i get on the 19's so myoverall diameter of the wheel remains the same. is it possible to keep to same diameter with 19 or do i have to get 18's

[Jim@tirerack]

The tire size would be a 245/35R19. This will keep the rolling diameter the same as stock. If I can help let me know.
