Hello,

After installing my new 315 tires on my 98 Featherlight, and after weighing I settled my tire pressure on 110 steers and 100 on drive and tags. I went on a trip from OKC to Minneapolis last week.

I am being extremely diligent about checking tires each time I leave on a trip and each morning during the trip

It was in the 70s (low) to 90's (high) in OKC. All pressure was perfect.

When I cked in Minneapolis (60's) low and 80's (high) I noticed the morning pressure had dropped 4 degrees equally on each tire. All tires were the same 4 degrees drop. I assume that this is natural due to different temps.

I decided to just keep the tires at that 4 degree drop knowing I was heading back to OKC where temps were higher again.

My question is is best to do this or should I air them up to my target temp in the future?

Thanks
