Cause it's not 50! LOL
It was about 70 outside this morning as the sun came up and the daily weather will be in the 80s this week. They were 44-46 this morning, last aired them up after Christmas. The driver's side gets the sun all day so those are always higher now to start with and they were the other day even after driving on the highway a while. So it was time.
seems little high, but assume you know what you doing.
