Thats also what I was looking for and 285 X 60 's.
But with 18" I was limited to my selection on wheels and tires. Every time I found a wheel I liked with that spec it was discontinued. Happened 3 times. So ended up with my 4th choice and 65's.
The back space and tire ratio I ended up, I knew both where pushing the limits.... Oh Well ... My Luck... but it has worked better than I was expecting.
Oh also, just FYI for anyone looking at any wheel tire combos... here is a Link to a cool wheel-tire calculator. You can put in your stock spec's and then see what happens with other combos. http://www.rimsntires.com/specs.jsp
