Only downside I do not like about running 285/30 or even worse 275/30 in the rear is that when it says you're going 80mph, seems like you're only going like 75. Kind of annoying to always do the math whenever you look at the speedo..
I got 295's and feels noticeably more accurate, I'm sure 275/35 would probably balance the OEM speedo error (reading too high).
