Yeah I think 17s and 18s are a tricky size for the box...I may just settle for 16x7s and get 205/50/r16 tires...what do you mean by 'offset'...my car has basically the same tires I had when I bought it 185/60r15...those wheels look good.
heres the tire size calculator I just plug in numbers and go from there...
I looked on there,it says that the closest to keep the speedometer accurate would be a 215/40r17.
that tire is going to be wider than a 205 so you might rub depending on your offset. I'd say you'd probally be ok with the 215.
just remember the first number is the width of the tire(215>205) second number is how tall the sidewall is(50>40) the last is the rim size.
BTW thanks...I just realized how foolish my first question was...
