Tire PSI
Is there anyone that has any real info on tire psi. I have talked with people I bought the tires from and looked on internet and still don't know the right answer . My sidewalls on truck and 5th wheel...

My truck sticker says Front 60, Rear 45 empty, 75 loaded. I run Front 60, Rear 50 unloaded because I always seem to have something in the back and 80 loaded which is sidewall.
I run 80 in my E trailer tires which is sidewall.
Most fifth wheel tires are not evenly loaded as one side is usually heavier than the other and front to rear loading can also vary for different reasons. Grand Design weighs every trailer and includes a weight sheet in the documentation. Empty, my left side trailer tires are carrying 600 lbs more than the right and as most inside storage is also on the left side, it is probably closer to 900 lbs loaded.
Remember that manufacturer's load inflation charts are just giving you the maximum load rating for different pressures, they are not recommended pressures. The reason tires are lower weight rated at lower pressures is because they generate more heat. Where you set your pressures is a matter of your own comfort level. I err on the side of more capacity
