I own a 2006 41 foot 5th wheel sportster toy hauler. According to owners manual and internet I should have a data plate on front left side of trailer showing tire and inflation info. I got the data plate put important info has faded away. Cannot find anything on internet showing what a 41 foot toy hauler tire pressure should be. Tire info on tire states max load at 80 PSI. Tires look as though they are over-inflated. Dropped to 70 psi as an educated guess. Anyone got nything on this that might help? Thanks.
If you know the weight on the axles, you can check the tire manufacturers recommendation for inflation pressure. Until you know the actual weight each tire is carrying, you should use the maximum pressure (80 PSI) to be safe. One such cart is available here: link
