Special rubber tires are made slightly conducting, in aircrafts, to enable them to pass on charge (produced by friction) to the ground, as too much charge may result in a spark and hence cause a fire. This is apparently the same reason why some vehicles usually have metallic ropes touching the ground during motion especially when they carry inflammable materials. But I don't get how exactly the charge causes the spark.
