For two weeks and about 250 miles now I've been running new wheels and tires mounted and balanced and shipped to me by Tire Rack. There was no mention of TPMS in the transaction. I expected to see a warning light, but so far, nothing, nada, zilch.

The wheels are SVT (Ford) "Fanblades", the tires Bridgestone Potenza RE-01Rs. Nearly eight pounds per corner heavier than the stock 16" with BFG, and a bit heavier than the 17" Bullitt/Pirellis they replaced .

You don't suppose the four taken-off tires/wheels in a stack eight feet from where the car spends the night influence the warning light, do you? The car's been away from home as long as eight hours at a time.
