Larry , I had the same trouble trying to find a wheel to handle 2500 lbs plus. I ended up purchasing two wheels manufactured by Martin. Martin has been manufacturing wheels for over 60 years. The wheels I purchased are rated at 2050 lbs. @ 75 psi. I also ordered my Powerking Towmax tires from Amazon. The tires are 6 months old. Here is the link for the wheels Martin Wheel 5-Hole Steel Custom Spoke Trailer Wheel (15x6" / 5x4.5")
