Races are so much easier to win when you put the Soft tires on, that you can afford to make mistakes and still beat AI with better performance cars, is this intended? I know that they give you best grip, but sometimes it feels like cheating :) The difficulty with Medium tires is little more challenging and with Hard tires it gets pretty difficult sometimes (you can't afford to make mistakes, worse acceleration, grip, ...).
I didn't find any difficulty settings in GT5 (except for assists), so I was thinking - are the Hard/Medium/Soft tires equivalent to Hard/Normal/Easy difficulty?
I'm talking about A-SPEC races here of course, special events/licences have their difficulty indicated by bronze/silver/gold trophies.
I've not played previous Gran Turismo games and I've just sunk myself into GT5, so I don't know if it's like a common GT-way of doing things?
