[QUOTE=Topless;302429]I do it all the time but... The tires must be of very similar design, compound, wear rating, and sidewall stiffness or you will get very ugly handling in this car. Mixing Hankook V12s and Pilot Sports will be very compatible. Mixing Italian All Season tires with fresh max performance summer tires will likely turn into a very spooky and unpredictable ride.

A/S tires on the front: Massive understeer and front tires hitting ABS quickly under braking.

A/S tires on the rear: Turns a mild mannered Boxster into a tail happy Viper. Backing the car into a guard rail will be very easy to do.

+1 this is the key. Never drive your vehicle beyond the capability of the driver or the vehicle. The weakest link will fail if you exceed it's capability. You are usually safe when you are just replacing the rear tires with tires compatable with the front tires. Now as long as you don't exceed the capability of the front tires there's no problem.
