  "textContent": "This invention relates to a farm tire, especially a farm tractor drive tire, with a tread having a running surface of significantly spaced apart lugs designed to be soil engaging of a rubber composition comprised of at least one conjugated diene-based elastomer which contains an organosilane polysulfide in situ coupled dispersion of reinforcing filler as a pre-formed starch/plasticizer complexed composite. The running surface of the farm tire tread itself is of a configuration comprised of widely spaced apart raised lugs to provide a ratio of net running surface of the tread lugs to the tread's gross dimensions (net to gross ratio expressed in terms of percentage of the running surface of the lugs) in a range of from 15 percent to 20 percent. Therefore, operationally in the field, normally few lugs actually touch, or engage, the ground at any one time. Accordingly, such individual tread lugs are desirably capable of experiencing locally high loads and should be sufficiently stiff to resist extensive elongations.",
