We have weighed our motorcoach but were only able to weigh the front and real axles, not the individual tire weights. The question is, how much do forum members compensate for not knowing the individual tire weights?. Thanks. Larry
We run max cold tire pressure all the way around as indicated on the tire sidewall. 110 psi with the tires we have now. Also never adjust pressure in hot weather even in summer in Death Valley

Max sidewall pressure causes several issues if not the actual load the tire is carrying.
Noticeable feedback from sharp road hits like expansion joints and you are running on the center of the tire more than the edges.
Not full contact. The max pressure is for that exact max load on the sidewall.

The recommended method is ,for example, the front axle: Divide axle weight by 2 to get the two tire weights and then add an estimate for the side-to-side weight difference. You should be safe adding 500 lbs for the front axle - then use the tire inflation table to get the correct inflation for the load. By the way, my single slide U320 had no significant side-to-side difference on the front axle, but the passenger rear side was +900 lbs compared to the left. I'll bet others with the same coach as yours can give you numbers based on their individual wheel position weights.
Assuming you don't exceed the tire or rim PSI maximums, add 5 PSI for side to side imbalance and 5 PSI for a safety reserve= 10 PSI.

Thanks for the replies. I am going with Brett's example of adding 10 psi to each tire. By the way, adding 500 pounds to the front tires and 900 pounds to the rear tires to compensate for only weighing the axles as suggested by Jeff resulted in adding the same 10 psi to each tire. Larry
