Camden:
To digress slightly... Insane states he has 225 45 17 wheels with sports suspension.How does it ride? My Volvo has 215 45 17 wheels and std suspension and rides like a dray ! Handles well though.Not all Volvo owners are old fossills with a lab in the back!
It's a firm ride to put it politely, and not ideal for poor road surfaces taking some getting used to coming from a 1999 1.8L Nissan Primera with 185/70/14's. (9L/100km around town on that car)
I notice the bumps particularly on roads where large truks/buses have caused corrugations in the road surface from breaking heavily, and the drive from Christchurch to Auckland when I first bought it left my lower back feeling a bit uncomfortable by the time I reached Hamilton.
I wouldn't dream of putting thinner tires on it though as the traction control already kicks in from time to time dealing with the 320nm of torque, and I really enjoy the way the car holds on the road as if on rails.
