18s or 19s in regards to tire options

[CamaroJesse]

I'm getting ready to pull the trigger on some forgelines or ccw's. I'm doing 18s up front but I'm on the fence about 18s or 19s for the rear. If I go 18s I'd run a 315/3018. If I go 19s I'd probably run a 325/30/19. I'm wondering if the 19s might be a better choice because there are factory vehicles that use this size and might be more available and have more options to choose from. I like the look of both although I haven't seen too many with the 18/19 combo.

I'm running 325/30/19 in the rear, and they look and fit great. However, I'm also running 19's up front as well. 67' Camaro. Guess it just comes down to personal preference. At the time I made my decision, I couldn't get the rim I wanted in anything less than 19".
