Tire Pressure

I have searched all the forums and also looked at the tire pressure charts for the manufacturer but I still don't know what to inflate my tires. At 7 to 8 hundred a piece I want them to last until they dry rot. I weighted my coach and got the following numbers.

Steer Axle 13920
trailer Axle 21700

Total 35620

Motorhome Info:

GVWR 46000
GAWR FRONT AXLE 16000
RGAWR 30000
TOAD WEIGHT 4200

FUEL WAS ABOUT 75 GALLONS NO WATER, I AM RUNNING ABOUT 110 ON 305 22.5 MICHELIN TIRE WITH TAG AXLE

did you add the tow car and the fuel and water
4200 # for car, 75 gal fuel@7 #;s and 110 water @ 7# for a total of extra weight of 41083. Do you add all of that to rear tire or put some on the front. Putting about 200 on front and 300 on rear that would make the pressure on the rear # 24000 and 16000 on front, did I do that right

Adding a tow car will not change the rear or tag axle pressures required as all weight that's added should be less than 100#'s total.
Diesel = 7.15#'s/US gal
Water = 8.35#'s/US gal

On our DSDP I have about 13,200 on the front axle and run my 305/70's at 100 psi.
Rear axle is just under 19,000 on 275/70's, I run 90 psi.
No tag.

I stepped up one additional weight limit and used that tire pressure because lower weight would be under numbers you posted.
Some people do add 5lb's for safety, I never do because the tires are going to heat up while traveling 10 to 15 lb's.
Thats why you check tires when cold never try to adjust when hot.
