My girlfriend has a 05 scion tc limited edition. It has the 18 inch black tires/rims. She is always having problems with her tire light coming on. The dealership is full of BS and never fixes the problem. Her psi is always 40 or above, but never all the same... Anyways, I just looked in her driver side door and it says the front tires should be 32, and the rear should be 29... So I just check and two of the tires were at 60 and the other two at 50-55.... I fixed it to what the door said... is that too low of a psi to have...32 and 29.. I'm alittle worried. She said it's feels great... I'm worried???? Thanks!

Re: 2005 Scion Tc - Tire Pressure
It should be what the door says... but make sure the door is showing the size of tires that are on the vehicle... tire pressures are usually determined by an engineer for that vehicle and tire size
Also what does the sideway of the tire say ?

depends on how you drive, the car will tell you when you need to change the oil, tire pressure, most tire shops will tell you 5000 miles then rotate tires, remember front to back same side do not change right sides for left sides, as far as trans oil, never, wipers depends on what kind of area you are in.
It sounds like the tire pressure monitor warning light. Does the light look like this? Check and adjust the pressure in all the tires (most Toyotas even monitor the spare tire pressure so check that also). If you find one tire with significantly lower air pressure then the rest bring the car to a repair shop to have them find and repair the leak. Once the air in the tires are correct the light will go off.
You shouldn't be setting the tire pressure to the max inflation pressure listed on the sidewall, that will likely result in uneven tire wear with the center of the tire wearing out prematurely. You should set the pressures according to the listings in the door jam. Most likely 32-34psi. Also, have you checked the spare tire? Some systems monitor and will illuminate the TPMS light if the spare tire pressure isn't within an acceptable range. The spare is often overlooked when checking tire pressures because of a TPMS indicator.
the light means that there is still a problem with the tire system, if there is a spare make sure to check that. If the light is still on after setting all tire pressures then there is most likely one of your tire pressure sensors bad which is the valve stem if equipped. What you can try is pump all tire pressures up to about 45 psi, then qiuckly let the air out one tire at a time. This kinda wakes up the system. If this doesn't solve it then you will have to take it to the dealer.
