    I like those much more. Cool shape and color for the car.

    The new wheels do look good. Mind you, I do also think those 13" wheels with the deep sidewalls look good too! I'd be tempted by a set in the UK if I could get them.

    I was wondering what you did with your spare. Did you replace it with a 15 inch spare?

    No...and here's why...

    The important numbers to compare are the diameters of the tires...not the size of the wheels. The spare tire should be the same diameter as the stock 165-65-14 Enasaves (22.4 inches). The 185-55-15 tires I am using are 23" inches in diameter. That is less than a 2.5% difference in overall diameter...which isn't enough to cause issues with the car's computer.

    Remember...the computer doesn't know (or care) if it has 13" wheels or 20" wheels. But what it does know (from each wheel speed sensor) is how many revolutions each wheel is making in a certain period of time. As long as the values from all 4 wheel speed sensors are approximately the same (within a few percent), everything should be OK.

    This is interesting. I didn't know the Mirage computer makes comparative computations on wheel speed. I would like to know more about this in our cars.

    The system is constantly checking the rotational speed of each individual wheel thousands of time per second. It's the basis of the ASC (Anti-Skid Control), TC (Traction Control) and the ABS (Anti-Lock Brake System). At least in the US version, when you shut off the ASC with the button it also shuts off the other two systems as well. There are a few Youtube videos that show Mitsubishi demonstrating the system. Pretty impressive actually for such an inexpensive car, to have such a sophisticated integrated system. You can't violate the laws of physics of course but the system will definitely perform at a level above 99% of the capabilities of most drivers.

    Of course! For some reason I was focused on TPMS and forgot about ASC, TC & anti-lock brakes.

    When I read my owner's manual I was under the assumption that you could turn off traction control but stability always stayed on. If you want to feel the stability control, whip a corner with the accelerator planted and cut the wheel real hard, you'll feel the engine lose power for a couple seconds as the stability control cuts the throttle.
