Your car came with two O2 sensors. The sensor you’re missing basically only tests the catalytic converter, which you probably don’t have any more either. But you still have the one right behind your engine, take flashlight and look; it is right next to the fire wall. If in fact your O2 sensor is bad you will never get good gas mileage. And yes, the reason you don’t have a code is because of your tune. But like I said before, the EGR is probably your only real problem.

Your observations are pretty spot on. EGRs don’t open at idle, or at WOT. They do open after your engine is warm and cruising.

And as for your tire question you just posted, I have already given my pressure advice. As far as after market rim damage. Well, IMO it is a two part problem. The side wall thickness of your tire, and the design of your rims. The lower the tire side wall; the more susceptible/exposed to damage the rims are. And after market rims tend to be weaker than stockers.

Having the tire pressure in a reasonable range shouldn’t really affect rim damage. When you put on your stock tires for winter, you should note they probably say 44psi max. Just run your tire pressures some where between 30-35psi, any higher or lower you’re just asking for trouble.
