Just recently put on LT305/55r20 nitto terra graps for past couple of hundred miles. NTB put them all at 35 and you could see the sidewall bulge a little and after about 80 miles and inspecting the wear on the mold **** the center was not touching as much as the shoulder. Put them at 42 front 40 rear for now. Rides firmer with more air of course but it is by no means bad at that pressure and it looks like its wearing a little more evenly so far. I think 45/42 may be perfect for these and DD use

I am running 58 psi front and rear all summer as we are towing many 1,000's of miles with our TT. Works great for towing.
In the winter, I plan on dropping down to around 46 for a better ride.
