"This is a MARATHON PLUS (M/PLUS)  heavy duty service rated tube and is approximately 10% to 20% heavier inconstruction than standard service rated tubes. We recommend these tubes to be fitted in applications whereextra stresses are involved and the tube is required to conform to the tyre in multiple directions as the tyre movesand flexes during service. Perfect for most radial and cross ply tractor tyres."
