I need to borrow the smallest 5 x 4.5 tires anyone has access to. I still can't pass smog but I've made progress. After Sea Foaming the engine, running a tank of Guaranteed to Pass, getting the new cat (4-5 weeks old) really hot, replacing the upstream O2 sensor (3-4 months ago), repairing an exhaust leak upstream of the cat and running 30x9.5 tires (instead of 31x10.5), I still failed.

My NOx is down to 750 ish on a 525 limit at 15 mph. It's down from 2000 and 1100.

I'm pretty confident that stock tires (in the 27-28 inch range) will finally get to me pass.

I'm desperate at this point, my registration is up tomorrow. No mechanic wants to look at it because they know how hard 4cyl Jeeps are to pass.

Fourth time's the charm right?
