New Mexico Tractor Trailer Weight and Dimension Limits



New Mexico has some increased gross weight capabilities across the state. There is the possibility of having gross weights up to 86,400 lbs, but with very specific wheelbase requirements. See the New Mexico trucker’s guide for exact spacings, but truck trailer combination must have a wheelbase of 56’ to be able to take advantage of the higher gross available. Also, axle weights are different, with single axle weights being slightly higher, and tandem weights being slightly higher at close spacing, but lower at higher spacings. Tridems are penalized under the NM weight tables. For those shippers moving low density products, the availability of 57’6” trailers is of interest.
