On 1790 16/32 CCS planter the book says main frame tires - 60 psi and wing tires 40 psi. Started inflating main frame tires and noticed on the tires said max 75 psi cold and the wing tires said 60 psi cold. My question is which one is right. On all other equipment the book has always said the same as what the tire max said.
