Tire Pressures

Question

HelloI have a 2017 Coachmen Mirada.&nbsp; It weighs 18,340 lbs. fully loaded.&nbsp; 6040 in the front and 12300 in the rear.&nbsp; I have read every forum out there as well as anything I can find on google or you tube, etc.&nbsp; Still can't find a decent answer as to what pressures I should run or is recommended.&nbsp; And when I go to the Hercules chart for pressures all it gives is the max pressure that's on the sidewall.&nbsp; Sticker in the cab says to run 92 psi which I typically do but it seems to be kind of a harsh ride.&nbsp; &nbsp;Just looking for a general opinion on this.&nbsp; Thanks!&nbsp;&nbsp;

&nbsp;the drivers door frame what tire pressure is recomended for that vehicle, if you are on the same load rating and size then that tag is what you should use.&nbsp; if you changed up the tires load range and went to a different sized tire then you might have to email the tire maker and ask them for their load inflation charts.&nbsp; pick the psi that is proper for the weights, and I always add 5lbs to that for a safty margin.&nbsp;&nbsp;

Thanks!&nbsp; A bit new to the class A motorhome thing so I think I'll stick with the sticker pressure and quit worrying/wondering about it.

Use a load inflation table for your size tires. 19.5 rims are 70-80psi min due to the bead design. And go up from there to min safe pressure for your load, cold.
Guess is if you’re at 90, can’t go much lower for 245s (likely your size).

sorry, your not making any sence.&nbsp; his tires are rated for the weight, and in the end he decided to keep them at what the manufacturer recomends.&nbsp; He was just asking if he should go by a weight chart and adjust the pressure to the PSI for the actual weight on the tire.&nbsp; He is within the capacity of the tires.&nbsp;&nbsp;
