The largest diameter wheel we carry with a 4 on 4 bolt pattern is a 13 inch wheel. The largest tire for a 13 inch wheel is an ST185/80-13 tire, part # AM1ST79, which you can then put on a 13 by 4-1/2 inch wheel, part # AM20242. It has an outer diameter of 24.4 inches and is 7.2 inches wide. The only catch here is this is a bias tire, which might be great if you'll be towing on rough roads a lot of the time.

If you're primarily going to be on highways I recommend going with a radial tire instead. In which case you need to go down to an ST175/80-13 size tire, part # LHWL101. If this is the case you're not losing much size here. The smaller radial is 24.1 inches in diameter and 7 inches wide. It also has a slightly lower weight capacity at 1,650 pounds at 70 psi compared to the bias tire's 1,710 at 65 psi but if you go with the wheel I mentioned you're still limited to its capacity of 1,660 pounds.
