Which of the following most accurately describes the problem?

• Bandag is planning to introduce low rolling resistance retreads to Europe next year. They will be similar to the Fuel Mixer Bandag retreads which first became available in the USA last March but they will not carry the same name.

Bandag claims that the rolling resistance of its new tread compound is lower than that of any other retread (and even lower than that of many new radial truck tyres) and that this can translate into fuel economy savings of as much as 11% on a 38-tonne GCW, five-axle combination.

The company admits, however, that tread life with the low rolling resistance compound will probably be about 5-10% less than with a conventional Bandag retread.

Floyd Myers, head of Bandag's research and development unit at its Muscatine, Iowa headquarters says that his tests showed a Michelin 285/80 R 22.5 at maximum load and pressure to have a rolling resistance of 40 It/tonne. This was his target for the Bandag Fuel Mixer, he says.

Fleet trials of the new retread are currently underway in mainland Europe.

Like all Bandag retreads, the new tread is of the pre-cured type.
