I recommend a 5-lug setup. For this you would have to get the tire and the wheel separately. You could go with the Karrier ST225/75R15 Radial Tire # AM10303, it has a weight capacity of 2,830 lbs at 80 psi and a speed rating of 81 mph for your tires. Then for your wheel, a Dexstar 15" White Spoke Wheel part # AM20532.

This new size will be around 1" larger in diameter than a set of 205/75-14 wheels/tire. That said, only half of this will need to be factored into your measurements to determine the fit.

It looks like you have already measured so the new wheels/tire would give you 2-1/2" between the top of tire and bottom of fender and 2" between each tire. This is less than what we recommend but still doable.
