OK..two more questions - understand the 20" Bridgestones can be very loud so I will avoid those if I go with 20". Go with Dunlop. What about the 19" RFT, anyone having road noise issues and what brand do you have?

I have also read on another forum abuot some people with new 2011 30i have experienced rough/hesitant/jerky acceleration between 0mph and 10mph with the new 30i. Apparently there is a fix, but just wondering if anyone else has experienced this on this forum. Thanks!
