Big Rims, Small Sidewalls. Why?
Right now 2016 TLX SH-AWD has 225/50R18 and they're ridiculously big and heavy. Honda Accord comes with 215/55R17 or 235/40R19. Even a Corolla goes from 195/65R15 to 215/45R17! To me, this is getting ridiculous.
Edit: Forgot to mention that a lot of times, the brakes that hide behind these large rims are sized so they normally fit on 16" or 17" rims. So with 19" rims but small brakes, again no point in my opinion.
