Put winter tires on last week, then it warmed up, lol. Anyway the roads I live on are township roads and although they keep the hills descent, most of the time, the rest are usually just plowed and not treated. Found out that the tire shop must leave the wheels in the same spots unless they have the sensor reprogrammer. Otherwise the system will read pressure incorrectly. Luckily the dealership fixed the problem in less then 15 minutes and didn't charge me anything.
