Need help -- get Nitto Invo tire, or Michelin PS2 at twice the cost?

I don't think it's an economic issue necessarily. Tire selection in general is always a compromise taking into account all of the conditions that will be experienced. The best dry tires are not the best in rain and vice versa. Four identical summer tires are not going to help you on that icy patch.

As an experienced auto-crosser I've slid from one end on one turn and the other end on the next with four identical tires. Unfortunately there is no tire combination that can compensate for driver error.

There is no excuse for driving on inferior or damaged equipment at any time but its been my experience that two brands of matching tires of similar specification on opposite ends do not adversely effect handling.

Each tires have its own limit on wet/dry/cold/warm/icy/snowy conditions, not to mention different wear levels and there's already so many variables out there, using mismatch tires just throws another unknown variable out there that will effect handling that can be minimized. It's fine if you want to play with different tires at auto-x or at the track, but on the street there's very little room for error when you have other cars around you. That's my 2 cents.
