Yeah, you're probably right, although it's not really something that bothers me as they look alright enough. TBH though its a pretty comfortable ride, less jarring than I remember it being on my old rims which were megaSport JAPturbo type affairs. Here's a comparison:
I think the old ones were only 16" w/ Toyo Proxes, the new car has Michelin Energy on each corner both 195/50 I think. Actually, the ride was probably more down to the suspension.
