I was looking in my new Rand Mcnally Atlas for the kingpin to tandem settings all I found was the bridge formula. So I did a search and came up with this document. Some of you experienced drivers tell me if this looks right or is there some place else you get this information?
A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".
