    assuming they arn't split up....a single can take 20/k. Tandem is 34k Tridem is 51k. Some of this may vary by state. Keep in mind your still limited by gross to 80k unless you have permits.

    Federal limit on a tridem with out a permit is 42,000 if it has a 10 ft spread it goes to 43,500. Some states may allow more but usually not on interstates. If your permitting weight then most standard is 20,000 an axle but again some states may allow more.

    thanks for the response it has 60 inch axle spacing. I was told i could be 36,500 but thought that sounded wrong. thank you

    Unless your getting permits the tri doesnt get you any more weight than a spread pair. It also seems to take up the same space. The only situation that makes sense is when you have the small tires that are a low load rating.

    Some states is 42K all the way up to 51K (IN)... LA will allow Non-Interstate highways: Single – 20,000 Tandem – 37,000 Tridem – 45,000.... 80,000 Gross (with a Tridem axle, 83,400 on Interstate & 88,000 non-Interstate if licensed for it)
    Also be aware of your kingpin setting and most of all, updating your IRP to have the privilege of hauling heavy and trust me they do check, some states won't issue a heavy permit without proof of your heavy IRP ;)

    so i can be 42,000 on the tridem in any state without permit as long as i do not exceed 80,000
