Can naff tyres make that much of a difference?
You can't compare the ST with other hot hatches. The Fiesta has one of the best suspensions but that also means it's not very comfortable to drive around.
Buying good tires will help improve the handling, but you won't feel any great difference in comfort. 5% more profile height also won't make a big difference. Mine don't get more comfortable when I change from summer wheels (standard Pirelli PZero Nero 195/45R16 on 7x16; 17" were optional wheels here) to winter wheels (185/55R15 on 7x15").
Accept it or buy a different car
