Weird, I'm not even finding many sizes in 16" that will even work, much less affordable... then again, I'm insisting on at least 215 width too, with all the torque of e30... but there are TONS of cheap off-brand and even solid $100 choices of tires in 17", it's just a matter of what has decent all around general traction in wet and dry while ALSO having decent grip in performance driving situations.
