Hey Randy,
With a 33" spacing you'd have approximately 4.6" between the tires of the # AM32545. You'll want to also measure the vertical distance between the tire and fenders as well as the horizontal distance between the tire and trailer body/frame. You'll want to have at least 1" for the horizontal measurement and at least 3" for the vertical measurement when the new wheels/tires are installed to accommodate suspension travel. view full answer...
