The 2003 Toyota Sienna is available with two tire sizes, depending on trim package. The XLE V6 models have P215/65R15 tires and both the CE and LE models use a P205/70R15. All models use the same 15 diameter, 6.5 width wheel with A5 lug X114.3 mm wheel bolt pattern. The tires should have 35 ponds of pressure in each tire. The Sienna has a tire pressure monitoring system that communicates with sensors in the tires. When the pressure falls just a few pounds below the recommended pressure, the system will alert the driver. When the TPMS light illuminates, inflate the tires as soon as possible. Proper tire inflation helps with the fuel economy and keeps the tires from wearing prematurely.
