Instead of going back with 295's I put 315/80's on the front and 11 R 225 on the rear. 11R,s which are the same diameter as a 295 takes 10 psi more to carry the same load. The 315 takes aprox 10 psi less .pressures. I run 105 F , 100 drive, and 90 tag which is 5 over what. I need. I'm on the heavy side so doubt you would have to run more. I paid $400 for the Hankook,s 11R 18 months ago.
And just what size does one doing that carry as a spare??? And is all that monkeying around with inflation pressure really worth it ? I run 115 front and 110 rear and have MUCH MORE carrying capacity that I even have room to load in the coach. There is a lot better answer than what you arrived at
