tire pressure
what kind of pressure are we supposed to run on stock set of tires for an SC300? i recently go new bridgestones which stick to the road like glue and is awesome for the price but i think the guys that installed it pumped up the air in it too much! the cars ride is way harsh and doesn't feel like a lexus anymore.

Almost asked this question myself. Currently I'm running 36, but the door recommends 32. I think the tire will handle 44 (maybe 42, can't remember offhand). Any handling advantages to running higher pressures, or is there a reasonable limit (other than the tire's rated limit)? From what I've heard (and from what makes logical sense) is that lower pressures will give better straight-line traction (and worse wear) but higher pressures keep the tire more geometrically corrrect under cornering forces.

I keep it at the Lexus recommended pressure of 32 psi. Any higher, and you will get excessive wear. Any lower, and you will cause excessive heat build up in the tires, which leads to premature failure. For regular driving, keep it at the recommended level. As far as on the track, well, you can do whatever will produce the best times.

I was wondering, since overinflating tires decreases contact patch, wouldn't there be more pressure on the tire to road and thus more resistance to hydroplaning?
