Loud & Noisey A/C , Under Size Tires

[Tommy T]

I have a Dometic Brisk 2, 15000 btu ac that is so loud we can not talk to one another when it's on, it's hard to stay in the unit because it is so loud (fan is loud by itself) is it the new R-410 refrigerant that is harder to compress ? Are do I just have a lemon ? Only 1 month old. GD & my dealer have been of no help! Does anyone else have this problem ? (Tires)My unit is 9100 lb dry & 2840 ccc, my tires are 2540 lb max load & only 65 psi seems to be under sized ? Axles are 5080 lb ? These #'s don't add up. What am I missing.

You are forgetting about pin weight.

There is never a full load on the tires or axles, as there is weight either on the pin or the front landing gear.

If the tires are a concern, you can replace with Maxxis Load Range E for more capacity. That is what I did on my Cougar.
