Classic weights and capacities?

Looking at tires, and got stuck in a loop with what the actual weights are for our motorhomes.
Airstream states my 1984 345 as follows:
ASW 14300#
Gvwr 16500#

They give the axle capacities as:
Front axle 5000#
Drive axle 10000#
Tag axle 3000#

Originally these came with 8 ply tires in 8r19.5,but I cannot find the load rating for those.
I am planning to swap to metric 225/70 19.5 which are commonly 12 ply and Load Range F which is 3640# single and 3415# dual. More than enough by the numbers.
Interestingly the OEM style Alcoa alloys I bought last year are only rated to 2750#.

I know someone weighed their 345 a while back but I cannot find the thread or anything with this dumb search engine!
Anyone taken their rig to the weigh station and have that info to hand or direct me to a thread?

Bump:
Anyone?
I could have sworn someone had weighed their Classic recently and posted the results with corner weights, but I just cannot find it!

These are the specs for the Goodyear G647 8x19.5 tires that I run.

Speed Rating (MPH/KPH) 75
Single Max Load (LBS/KG) 3,525/1,600
Single Inflation(PSI/KPA) 110/760
Dual Max Load (LBS/KG) 3,415/1,550
Dual Inflation (PSI/KPA) 110/760

It really doesn't matter what tire or wheel combination you run, the component with the lowest capacity determines the ultimate capacity.

Also realize that just because you have a 10,000 lb. axle and a 3,000lb. tag you do not have 13,000lb. capacity. Axles located together as tandems have a reduced capacity just as tires mounted as duals have less capacity than the same tire mounted as a single. If you go to the DOT site and look up the "Bridge Formula" you will get a headache as you try to figure everything they use to determine load capacity.

The real problem is most of the coaches built during the era of our classics are running overweight because after the coach was added to the chassis there was little capacity left for passengers and gear. Heavier chassis cost more and road rougher and we don't have to stop at truck scales so without a mean of enforcement nobody cares.

I think technology has changed a bit since the OEM tire days of your coach as tires now are running Kevlar belts as opposed to just steel so these Toyo are only a 4 belt design, but I think are the same F load rating.

https://www.toyotires.com/commercial...-position-tire

The Hankook AH11 has a F load rating but I have a feeling that the 8R19.5's are being discontinued.

As for weight; I did weigh my Classic the fall I ripped out the front floor, before cabinets and flooring went in. I should get a new weight done this spring.

I was actually surprised at how much it weighed. I would imagine I'm closer to 13,500 lbs now that everything is done and the coach has its regular load out. The weight included a full tank of diesel and me in it.

Got it Tony.
I was just trying to get a feel for each axle loading in stock trim.
Derek sent me a shot of a a road test of a 310(I think), where they state that the "Net Weight" which was including Water, fuel, propane, but no passengers or supplies, and it reads like this:
Front Axle= 4700lb
Rear Axle= 8500lb
Total= 13200lb.
So, by the time you add 2x 150lb passengers in the cockpit, you are maxed!
Might have to get my honey to lay in the bed, to try to balance my 240lb out!

I cant find my weigh slips for the 270 but I recall it was 6+ tons.
But of course, if a cop asks, "It is 5 pounds less than the max allowed highway weight"
If you are looking for capacities here are a few items I acquired somewhere.
