Cepek FC-II 33x11.50r17

Hello all!
I am new to the forum and this is my first post... I havent had time to fill out my profile info but I need a lil quick advice.. I have an '08 JK with the above stated tire, I would just like to know what yall think the optimum highway psi on these suckers are since I am not the owner to have putem on originally..
I have been keeping them right at about 43.5 with it being really hot here in missouri, as it can fluctuate all the way up to 46 or 47 sometimes... I believe the max psi on these 33's is 60. Can anyone lend a helpful thought or bit of experience to a new jeeper. I am no stranger to off-roading and mechanics somewhat but would like to hear what yall have to say!

That seems really high to me. I run my 285/70/17s BFG KM2s (33x11.50) at about 28 on the street
