FWIW, posting for posterity in case someone comes here looking for this info.
I recently purchased a tire/wheel combo from Tire Rack and they shipped with 433MHz TPMS sensors. Everything I read online said 315MHz.
Even better, I slapped the wheels on the car, drove around for a bit and the car read the TPMS sensors no problem. No programming tool required.
Gotta love Tire Rack. I ordered the set from them at 3PM on Monday. Had the wheels/tires at my house by Noon the next day. I can't believe they pulled them from inventory, mounted, balanced them and shipped them prior to UPS picking up. Great service.
