Under normal driving conditions you may not notice any difference but if you push the car hard and approach it's limits, you may break the rear tires loose sooner than you should. That will occur without much, if any, warning. The whole suspension (including the tire sizes) was designed to prevent the rear breaking loose because of the high polar moment and the inertia inherent in a rear-engined car. Once you do get the rear tires loose the spin will probably be unrecoverable. Bottom line, if you do change tire sizes you must be aware you have changed the driving characteristics of the car. And not necessarily for the better. You might be able to compensate by changing tire pressures. Now you are really on your own!

That tells me that any size in between should fit, no? I'm in a financial bind at the moment, but the car desperately needs new tires for safety. The factory size are becoming more expensive as time goes on (though I did find a fly by midnight brand, I believe it was Eldorado Tire who had them for $95 a pop.) > > > > Can I go slightly smaller than factory?
