OK...Getting ready to pick up the Dutch Star with the following Axle ratings:
Front 14,200#
Drive 20,000#
Tag 10,000#
We are picking it up winterized so no water which is probably not an issue anyway with the tag axle. So, just for the sake of argument I was running numbers as if the axles were maxed out and equally balanced. Yes, I know about 4/6 corner weighing but I doubt I would be that hugely imbalanced with an unloaded MH to make any wheel weight higher than the average.
So, based on the tire pressure charts for Michelin, 305/70R22.5 LRL - XRV these are the "corner" tire weights and pressures I came up with.
Michelin North America RV Load & Inflation Tables
Front - 7,100# = 105 PSI
Drive - 10,000# = 80 PSI
Tag - 5,000# = 75 PSI (Minimum PSI)
These pressure setting numbers are RADICALLY different compared to my Winnebago where water and fuel are over the rear axle and have the rear tires at higher pressures. Seeing these numbers surprised me quite a bit. Am I making some stupid math error or missing something? Are these numbers typical for folks with similar tires?
These are replacing the same tires sizes from the Spartan factory.
I was just surprised at how "low" these numbers are. Thanks for double checking me.
