KSaiyuBut you CAN'T win on some races on level 5 with N2 tyres on, since the AI use sports tyres. Although they're stupid and insanely slow with them, they still have FAR more grip than you if you use N2 and you just can't win in these races.
My mistake... Do level 7 with sports tires. Meant to put sport tires and not N2. Sorry.
