sorry to hijack the thread but can you tell me what difference the PSS's made to ride quality? i find the 19's don't jar you but the ride is jittery and believe this is down to RFT's.

as far as sizing new tyres try this link to give you rolling sizes and wall heights etc

interestingly, as i was contemplating downsizing to 18's for comfort, the difference in wall height is only 16.5% compared to 19's, so i don't know if that would be noticeable. certainly not as much as just changing to non-rft's and keeping the same wheel size

edit:
SCBMW02. I just worked out that with your rears you have increased the side by 6mm, and fronts by 3.5mm which is halfway between the gain made by 18's on the rear (12.75mm normal difference) and less than a third on the fronts (11.25mm normal) but probably messed up your speedo?
