I recently picked up a Pro Angler and bought the less expensive cart with the skinny plastic wheels.
I did a quick upgrade to the cart with a set of wheels that cost me $10 at Harbor Frieght. It was really too easy.
First the washers that are welded to the axle were gently removed wtih a set of vice grips. A little back and forth bending will break the two welds.
Second I cut two sections of 1/2 copper pipe to cover the axle where the wheel will ride.
Added a couple of washers on the inside, put the wheel on, two more washers and finished it off with the pin in the axle.
