| The design on 200/50－10 6.50F M2 high performance pneumatic solid rubber tire for forklift was introduced. In the structure design，the following parameters were taken：overall diameter 460.2 mm，corss-section width 203 mm，width of running surface 177.6 mm，arc height of running surface 3.86 mm，bead diameter at rim seat 245 mm，bead width at rim seat 172 mm，maximum width position of cross-section（H1/H2) 0.809，using M2 large block pattern for forklift，pattern depth 7.5 mm，block/total ratio 77.6%，and number of pattern pitches 12.The lower mould steel ring was replaced to produce tires that met the two assembly requirements of rim applicable to standard and rim applicable to non locking pneumatic solid tire.In the construction design，the following processes were taken：three-formula composite structure for tread，and steel ring with structure of 7 steel wires×4 layers，269 mm in diameter and number of 5，using building machine with head diameter of 251 mm and head width of 300 mm to build tire and hot plate press to cure tire.The indoor test results of the finished tire showed that the inflated peripheral dimension，phsical property，static load performance and endurance performance met the requirements of the design and special vehicles. |
