Stop throwing away expensive ag wheels with worn bolt holes or cracked center discs. This reinforcing ring is an ideal way to get more life out of an expensive wheel. To use, dismount tire from wheel, straighten out the old broken center, put broken wheels on hub, put ring on and tighten down, check to see if wheel runs true, then tack-weld the reinforcing ring to the wheel. Tapers are already drilled for lug nuts. This ring has a standard 10 x 13" bolt pattern and a 11" center hole. 3/8" thick. Note: For low-speed agricultural use only.
