Perfect for my 17hp YardPro garden tractor. 42" 1999. The included E-clamps and washers/gaskets are the correct size. Zerc fittings are correctly installed and working properly. The sidewalls of the old tires were badly worn, so even with tubes installed and inflated to normal pressure, the front of the mower road was about 3/4 inch lower than with these new tires. Lani's lawn mower powers up and clears our 1 acre yard as it enters its 19th year of service with new front wheels and tires.
