I have a 3033r and the front tires are 27x8.50-15NHS. I have a used set of turf tires I want to use the but inside diameter of the rim is 3.5inchs. The inside diameter of my current tires is 4.5inchs. I would rather not have to swap the tires onto the 4.5inch rims, is there a source for some used rims that would fit? thanks.
