Can I run different front and rear tires?

Well, that's the worst case scenario (although for most people, chronic understeer is much safer than chronic oversteer).

High performance summer tyre up front and winter boots on the rear could make a nice combo.

Thanks for all the replies. Well, it looks like my Goodyear F1's have been discontinued, so I may be looking at replacing all four tires. Anyone in need of two tires for cheap?
