For touring tires, Goodyear Efficient Grip or BS Turanza T005A would be a better value for money than P4.

For UHP, try find Falken FK510, well proven good UHP tire with better value for money as well, usually just around 80-90% the prices PS4. Another better value is the newest Goodyear F1 Sport, also should be quite a bit cheaper than PS4.

If I were you I'd try the F1S coz usually Goodyear makes excellent tires which rival or even better than those of Michelin, especially the F1 line up.
