With 4 Ultra High Performance tires, then under-steer is an issue only when pushing very hard. With All-seasons up front and Ultra High Performance in the rear, the rear will grip beautifully, and the front will plow on straight, at a lower than anticipated speed.

Still, I'm thinking it's not a concern for the OP.

And FWIW, I've experienced under-steer and over-steer on the street. Plus there's emergency situations to consider; having all-seasons on the front just kills braking performance.
Does this same logic apply to a staggered set up?
