Our car came from the factory with 17" wheels, but now we have 205/55/15 tires on 15" aftermarket wheels. For winter we have a second set of the same wheels but in a 185/60/15, but they ride even worse! The summer tires ride pretty well, but a more compliant spring and damper package that allows for more body clearance would be nice. Then I could go with an even taller tire in the future.
mine were 155/80 R13
over an inch of extra side wall. Really smooths out small sharp edges of small pot holes.
most noticeable going over those small sleeping policemen we have here in the UK. Dont even notice them.
there's quite a difference between a 05 and 2010 in body stiffness
you can feel the difference just by pushing above the drivers doors. The 2010 is far stiffer. I suspect its the springs but have never checked
although they are basically the same the 500 has a wider track
