As long as the overall diameter of the weel/tire is the same. Most presure monitors use weel speed to determine underinflation- Can you replace them regular tires later on and still use the tire pressure monitor?
Since you can run on the flat tires because they have stiffer sidewalls, the ride is likely to be harsher.- How is the ride quality? Stiff or harsh?
I'm not sure how much the sports package is for the xis, but you'd likely spend more to get similar seats and a steering wheel. IMO, the sport seats are far superior to the normal seats.Thanks for the input. Get my 2004 330xi made in October and have a chance to change my mind. Currently I have the sport package ordered, but am thinking about changing my mind due to the tires.
