tire pressure vs. weight- the correct answer

[jfaberna]

I've been riding around with maximum pressures in my tires to be safe. At the recent National MOC rally, I had my truck and trailer weighed by tire position to see what the facts really were.

My measurements all came out really good, thanks in part to my DRW TV and G614 tires. However, I found out that at my current weight I could reduce the pressure in my G614s to 95-100 psi instead of 110 psi, which is the maximum. Trey Selman from RV Safety showed me the tire pressure recommended chart for both my truck and trailer based on my weight. They add 5 psi for safety and this will allow me to run 95-100 psi and decrease uneven wear in the tires and reduce the chance of impact damage to the tires by potholes, etc.

I also can reduce my TV tire pressures to provide a smoother ride.

Best $60 I've spent.

I also found out that the CAT public scales don't really help RVers because our weight is uneven across the axle. The fridge side is always the heaviest. So my pressures are set for the heaviest side and not the average.
