My assumption would be that it's to slightly reduce torque steer and tramlining, plus they're probably stickier rubber.
I've driven the EuroR, and it does have tramline issues as well. as for torque steer, not too sure. it wasn't my car, and wont want to trash it with the owner sitting right beside me.
