A method of retreading a used agricultural tire, the method comprising:
- (i) providing a used agricultural tire casing from the used agricultural tire;
- (ii) providing a cured rubber component having first and second planar surfaces;
- (iii) providing a plurality of lug cushion gums, wherein each lug cushion gum of the plurality of lug cushion gums contains a cure system comprising a stable dinitrile oxide compound;
- (iv) providing a plurality of lugs;
- and
- (v) mating the plurality of lug cushion gums to the plurality of lugs to form a plurality of mated lugs,
- (vi) mating the plurality of mated lugs to the cured rubber component to form a mated cured rubber component, and
- (vii) mating the mated cured rubber component to the used agricultural tire casing to form a pre-cured retread agricultural tire.
