Wheel & Tire Protrusion in Utah
Utah requires mudguards or flaps on vehicles altered from the original manufacturer's frame height — as well as on trucks of 10,500 lb GVWR or more, truck tractors, and trailers of 750 lb or more. They must be at least as wide as the tires they protect and directly in line with them.

What the law says
The requirement is waived where fenders or the body accomplish the same result, and vintage vehicles are exempt. There is no 2-inch allowance — that figure was fabricated. Note the trigger: altering ride height brings a vehicle within this rule.
