You will find, most people will recommend the same tires on all 4 corners be used.
Reason being is the tread patterns when in motion follow a certain path across the dry and wet ground - pretty logical.. If you run different tires, then you may aqua plain in an unplanned way for example..

p.s. I hope you arent planning to run rotational tires the wrong way!

IN fact, whilst i remember, on CSI NZ (or something similar to that).. that cop show investigating the extreme car crashes in NZ, they covered this topic where a r34 skyline was running 3 different types of tires and crashed.. this gave the cops reason to believe tires may have been a contributing factor.
