Yes, we have entered the generation where no air tubes will be there for tyres. ERW (Energy Return Wheel) has developed unique tyres which do not require traditional periodic air filling. In fact, these tyres are not completely closed. These tyres are made of a special type hard rubber which spreads over carbon rods that manages frictional force. So, get ready to ride on these tyres and enjoy long lasting rides without interruption. Let us hope these tyres extend to heavy vehicles as well.
