The 10″ Solid cushion tyre had a tread depth of 50mm when new. There was an average of 38.00mm wear on the tyres over a 2405 hour period. Therefore, according to the wear patterns being demonstrated, a total of hours exceeding 2800hrs are projected on this set of tyres. There are two phases in the life of the tyre. The first phase wears only on the lugs and the second phase wears on the remaining lugs and centre cushion built into the tyre. The second phase provides a 60% longer life because there is an increase in the contact area.
