jerking at high speeds

Today my car started jerking at high speeds on the highway (above 50mph) feels kinda like a "jump" as well. it will do it randomly not at a steady pace. all the plugs and wires have recently been replaced, as well as the carb rebuilt, doesnt sound like any misfiring. Im thinking it could be something with the tires...
