Keystone Raptor axles/tires rating

Hello, sorry for such a long post. But I have some serious concerns about trailer axle and tire weight ratings. I have a 2011 Keystone Raptor 300mp. Recently while on only the 2nd trip with this, I had 3 tire issues. first was a leak on the passenger side rear axle that a tire dealer patched. Second was a "tread separation" on the driver side rear axle, that was unable to be repaired. Two days after getting a replacement tire, it also started losing air. Turns out that the rim had a small crack/defect that was slowly leaking. The crack was approximately 1 inch in length almost dead center on the inner hub and almost impossible to see. Tire shop said it was probably a manufacturing defect. Wheel was ultimately replaced under warranty. Needless to say, I got very proficient in changing tires. I also started paying attention to tires and axle weight ratings. Dry weight is approx. 11,250 lbs, 3,150 lbs for cargo etc. and a hitch weight of around 2400lbs. During my troubles the trailer had two harleys in it (1500lbs) virtually no water (110 gal cap), waste tanks empty and the 30 gallon fuel tank with 3-5 gallons. Hardly fully loaded in my opinion. After the troubles, I went across a Cat Scale and the trailer axles were 12,156 lbs. The problem is the axles are 6000 lb GAWR and the tires are 235 80 R16 E rated for 3050 lbs each. According to the specs, I am not anywhere near fully loaded, but the math isn't working for me. This seems like a serious problem. Am I missing something?

thanks

What you have forgotten about when weighing the Trailer Axle. Is the weight of the four tires and rims is also added to the 12,156lbs. The weight of the wheel/tires are not being carried by the axle. A Towmax 235.80.16 E weighs 36lbs to give you an idea of tire weight. rim is probably good for about 20lbs. You just need to be sure that the tires are rated to handle 12,160lbs.

If your GVWR is 14,000lb or 14,500lb then the 6klb axles are perfectly fine. Toy Haulers GVWR is figured with a King Pin Weight of 20-25% of the GTW. As GVWR is the total weight that will be applied on the Chassis, Bumper to Bumper. Includes the King Pin weight.
