Yes, a worn out contact tip is the most common reason for wire feed problems but I would assume that that is the first thing 99.99% of people with wire welders will check. And if THAT's ok, then it has to be something else.
I forgot, it could also be that the liner isn't put in correctly. Not just at the drive rollers, but at the head of the gun too. All liners should come extra long so they can be trimmed to proper length. And most people don't get the liner all the way up into the gas diffuser.
