12,000 to over 20,000, depending om specifics.
Generally on a semi-tractor trailer the limit is 80,000lbs
16,000 - 18,000, depending on specifics.
Typically, 17k - 19k for a three axle freight truck.
You need to be more specific about the configuration. Is a single axle straight truck, a tandem axle straight truck, a tandem axle straight truck with additional lift axles, a tractor trailer...?
Standard tractor tires weigh 130-140lbs. Super singles weigh 200-210lbs.
Tires come in many sizes, so the weight varies greatly. Standard car tires weigh around 22 pounds. A light truck tire weighs about 35 pounds. Large truck and tractor tires weigh much more than that.

A sleeper berth equipped three axle bobtail tractor typically weighs between 16,000 and 18,000 lbs.
16,000 - 20,000 lbs usually for the front part ("truck", "tractor", "cab"). But the empty trailer adds several tons more. For example a 53 foot long simple box ("van") trailer weighs 10,000-15,000 with nothing in it. So a whole 65 foot long empty system (truck and trailer) weighs over 30,000 lbs. Shorter box, flatbed, and covered wagons systems would weigh less. Systems with an extra long truck or specialized systems, like some of those with tank and pumping equipment, may weigh more. Adding to this answer. I have a 2003 kenworth w900 with a stepdeck trailer and i weigh 32,000 empty.
