If your going to run this car at all agressively I recommend the higher pressures. It is sooo easy to get up over 100mph that the safer bet is higher pressures - especially with such low profile tires! The rule is simple - higher speeds require higher pressures.
But is it a good idea to run at max if you are driving at high speeds? I thought (not sure) when your tires heat up, as they do at maintained high speeds, their pressure goes up and chance of bursting increases.
People who drive for extended periods at high speeds usually run higher inflation pressures because a lower inflated tire will generate heat more quickly. As long as the pressure is not above the MAX recommend, there shouldn't be a problem. I am sure that someone out there can kick in the necessary details. Dan
the concencus before seemed to be that you sacrifice grip and comfort with higher pressures. If you want more bite in the tires, try lower pressure. i agree this will generate more heat in the tires, but if you operate these tires in their spec range, they should have zero problem. 34/38 was discussed
