will the tire pressure system work with bigger tires?

seal, did you have to reset the system? mine still comes on after the bigger tires. i was going to disconnect the battery for 10 minutes to reset it. would that work?

all 5 tires need the sensors and the presure has to be the same in all 5....that's all the system looks for.....reset won't help....
Tire pressure monitoring systems (TPMS) are now impossible to run from when buying a new vehicle. Every new vehicle made for sale in the USA has a direct TPM system as standard equipment. There are several exceptions though: the vehicle must have only four wheels (so no dual-wheeled trucks or motorcycles), and the GVWR must be less than 10,000lbs.
We carry sensors for all Toyota’s and Scion’s up to the 2008 model year.
The basics of the direct TPMS is that it uses a sensor in the wheel/tire to wirelessly relay pressure back to the driver on some sort of display. Some vehicles have a digital info screen that will show all four tire pressures (five pressures if spare has sensor) all the time. While others might just flash a low-tire-pressure light on the dash. There are also two different styles of sensors for this system: a valve sensor and a strap/band sensor. Only valve sensors are used by the direct system-equipped Toyota’s and Scion’s, although if you bought an aftermarket SmarTire TPM system, those use the sensors held on by a strap around the barrel of the wheel.
Several older Toyota’s and Scion’s use an indirect system and it will not affect the choice of switching aftermarket wheels or tires. The system runs off of the ABS/wheel-speed sensors which “count” the number of revolutions of each tire. If the right-front tire is low (25psi) it will spin faster than the left-front tire (35psi), so the ABS system will recognize this change and alert the driver with a flashing light near the gauge cluster and possibly a loud chime.
Toyota and Scion currently use several sensors from two companies: Pacific and TRW. The size of the sensor shouldn’t be a problem for many wheels, but if the valve hole is in the middle of the wheel’s barrel, then obviously the sensor will not fit properly. The wheel industries are aware of the valve sensors and are rushing to get most of their wheels TPMS-compatible. If you have any questions about the TPMS-fitment on a wheel that The Tire Rack sells, I can look up the wheel and confirm if it will work with your vehicle.

I had the same question... Discount Tire also felt that there were tire sensors in my factory wheels. I have an 07 with the 17" alloys.... So I made a couple of phone calls to some local dealers. Bottom line is the dealer can run your vin# to see if you have the option in 07 (08's all have direct) of direct tpms (inside the wheel) or indirect (which uses the ABS system). But they gave me the quickest way yet to tell if you even have the direct tpms. If you have a metal valve stem you have the direct tpms. If you have a rubber valve stem, you have indirect. Indirect will work with aftermarket wheels, direct will work with the majority of aftermarket wheels, but they will have to be transfered, usually at a fee per wheel. Hope it helps! I used the service depts of Sport city Toyota in Garland Texas and Toyota of Dallas for the info and they were more than willing to help.
I left the sensors in my stock tires. I check my pressure often enough on my own. I'd rather stay in the habit of checking them myself rather than trusting a light on my dash. Also, then if you ever air-down, you don't have the light on your dash screaming at you.
