tire pressure

hi, i was wondering if i should keep my tire pressure at the 30 psi in front and 26 psi for the back or shhould i maintian them at the place that i got my tires at that they set them at which is 32 or should i keep the tires psi near there max which is 44psi,

i have several books on this issue at work, wish i had it here.

the manufactior spec should be followed in most cases, and can normally be found on a sticker inside the driver's door. i do not recommend having tire pressure at or near the max pressure. slight overinfation can result in better fuel economy, improved high speed performance, and a harsher ride. by slight over inflation i mean 2-3psi, 5 psi max. any difference front and rear should be mantained, so if recommend is 30f/26r and you go up 3 psi then it should be 33f/29r

I think the correct tire psi for the sl is 28 in the front and 26 in the rear, but I always set them at around 30 to 32 dont go much higher then 32
