While dealers should-- natch, MUST-- check the tire PSI during PDI... for the love of everything holy people, it's also clearly the RIDER'S responsibility to check the tire pressure!

T-CLOCS ain't just for two-wheelers, folks.

Anyway, I'll echo Scotty-- on the 2010 RS I've had great luck with 18 psi up front, gives me great handling (albeit a bit bumpier than most-- I can deal with the bumps, I refuse to deal with a lack of precision).
