well bad for your suspension, i dont think so that much, i have used massive tires on corolla, although it affected the economy and stuff but suspension was fine, as afar as meter is concerned, its very difficult to calibrate, though i did it on myne but is a tedious process, as i said by stock usually speedos are fast and with your 185/65/14 tires your speedo will go slow by 3% and i think it will be balanced, still get the tires than contact me, i have gps speedo, we can see the exact error from it.
