How much weight can a single axle semi pull?

Some states allow a set of A-doubles to run at 92,000 lbs. Some states even allow A-triples, which may be allowed to be up to 129,000 lbs. However, it's going to depend on the specs of the truck itself. A soft drink distributor's truck may only have a 250

• 300 horsepower motor and a six speed transmission. This would be

a far cry from what you'd see pulling triple pup trailers.
