The tire being cold is all crap according to Mr. Rapp's the Chrysler Advanced Manufacturing and Electrical Engineer or better known as "One who knows a lot of ****" The TPM is designed to take into account cold/warm up times. One thing that is hard to remember is a sales man knows how to sell the car, while a repair tech should know how to fix the car. I just hate it when some sales person talks BS. I hate it more when I forget and believe their bull.
BTW like the color of your car
