Tire Pressure Light!

for one you can't just look at the tires to see if the pressure is okay, actually check with a gauge
and the way they work (i assume) is they relate the pressures to each other, as opposed to just looking for less pressure than spec, so when one is off by a little bit the light comes on.
the reason i say this is because i thought i had gotten a nail in a tire one time, but actually turned out to be a tack. the place i took it to had done the proper testing, but left too much pressure in the one tire. so when my TPMS went off (at first i was pissed) i checked with a gauge and got like 5 or so more lbs in that tire than the others. so even though there were 3 with the correct pressures, the fact that 1 was uneven made the system burn the warning lamp (which i like to call the butt)
you'd better check all the pressures because you don't want 1 to be buggin out, they can be expensive to replace. and if you got your new wheels at a shop and they did everything for you, they might have messed something up with one during the transition from stock to aftermarket

put a little extra in for better gas mileage 
Without getting into too much detail I can tell you my tires were over inflated to 40psi all around and I didnt get a warning light. I wouldnt have even known but checked the tires as soon as I got the car home and discovered this. I think it might only be looking for a low pressure threshold.
An industrious member could probably test this.
Anyone have a service manual yet?

I didnt get the Meisters i got Work VSXX's.. Im running 18 x 8 in the front and 18 x 9 in the rear with 225's all around. I love the way it sits and looks.. EVERYONE was wrong about the staggred look.. but im rubbing on the right side through hard turns and funny dips. Its going up on the lift today to figre out wtf is wrong

Makes sense. I checked my tire pressures this past weekend with my super-duper $1.99 PepBoys special tire pressure gauge and two of them were down to 28psi with no light. Seems as though the dealer I picked the car up from last week (brand new) couldn't manage to fill the tires to specification during their "69 point inspection" they do when they sell a car, which was obviously claimed to be done to pump sunshine up my rearend.
