Tire pressure

[thstone]

With a mid-engine car where the balance is very close to 50/50, the tire pressures would normally be about equal to create balanced handling (neither understeer or oversteer).

However, very few cars are sold with balanced handling - most cars have understeer to avoid an average driver getting into a situation that they can't control very well (oversteer).

Thus, the 29/36 recommended pressure to add a bit of understeer to the handling.

There are many things that affect the press. choices for a manufacturer, ride comfort, tire "responsiveness", weight distribution, heat build-up at sustained high speeds, and possibly the most important, tire load ratings. They have to err on the safe side of a vehicle loaded to maximun GVWR. The Box is already rear heavy, and driver/passenger weight would seem to be biased to the rear also.
Just my WAG, opinions vary!
