i ran 44 psi on my generals which were almost the same size as yours. only difference was my fronts were 245/35/20. I thought the ride and handling at 44 was good so i left it.
edit: check the max psi on your sidewalls and see if its too high. I think the max on my generals was 51ish. So 44 didnt seem to high for me.

if you live in the city, where alot of bump and holes, then 44psi wont be comfortable,
but you want to protect your wheels, so dont want to go low psi, i will say 40 or 42
for highway, 44 is ok and feel good
