I have an '85 runner and it has always passed on the fast pass. I had 4.88's with 33" tires and now currently 5:29's with 35's. But all of my recent tests were with 31" tires. I always ask for a driver who is very good at shifting gears at the emission station. And I always tell them it is an older tired engine so help it along. And that has been my method.
