New Tires
I done and made my choice and purchased 4 Sailun S637 tires for my Montana. I may have done the wrong thing and I guess time will tell. I'll keep you posted if I have any problems.

I have a fifthwheel with a GVWR of 24,000 pounds. It came with Goodyear, load range D, 65psi tires with a load rating of 3000 pounds per tire. When I ordered it I was told that due to my wheels selection, they could only put on the D range tires. Thus they derated my 7000 pound axles down to 6000 pounds.
WOW...I would be concerned if 5er does have a GVW of 24,000# and I only had 18,000# of tire weight coverage..."IF" loaded to full GVW, You would almost have to hope you had well MORE than a 6,000# pin weight just to break even...that would leave 18,000# or a little less on the three axles and the 6 "D" rated tires.
As you stated, sounds to me like limits are being pushed....and, it sounds like they're stating that YOU made the wheel selection, and could only use D rated tires due to your selection of wheels??, I personally, at the very least, would have 6 "E" rated Michelin RIBS or a comparable tire on your 5er....Doesn't make a lot of sense....the GVW of the 5er is 24,000, but if axes de-rated to only 6,000#, than in reality, they're stating, don't load over 18,000# on your 5er.....you don't have 6,000# of the 24,000# you could use due to the wheels you're saying you selected:h
ON EDIT: I'm ashamed, should have read your entire post...with 6 GY G614's, your 7,000# axles are covered and the 6 tires rated to handle 3750# each gives you 22,500# of coverage, so now you are MORE than covered with axle weight...figure pin weight, if you're loaded to 24,000# would "possibly" be 4800#...just a guesstimate...so you are good to go sounds like to me:)
