Treads in a tyre are the parts which come in contact with the Road surface. This is the part that provides the appropirate traction for the vehicle and does not wear off that easily. But in LCV’s, Trucks, HCV’s or Tanker lorries, due to heavy loads, constant usage of the vehicle the tread gets worn. Retreading the Old tyres for an commercial vehicle like Lorries is economical than buying a new one and than that for a Passenger vehicle.
Hence there are Retread shops around still, but concentrated in Chennai around the highway exits or entries, Old CBDs like parrys corner, triplicane etc. One such shop near Smith road.
