Which of the following most accurately describes the problem?

with a new puncture-resisting compound were conducted, last week, before Press representatives. A 34 by 7 tyre fitted to a Bedford 5-toriner withstood -the effects of drilling and incision by a bolt, and a car tyre lost only 1 lb. of pressure after being stabbed in 12 places with a bradawl.

The compound is known as Punctureprufe and has been introduced by Punctureprufe, Ltd., 1-7, Crawley Mews, Eversholt Street, London, N.W.! It was originally placed on the British market in 1937, but prodaction was held up during the war and it is only now that manufacture has become possible. During the war, it was used by the U.S.A. on vehicles of all kinds.

Punctureprufe is a liquid and is introduced into the inner tube in quantities varying according to the size of tyre. Two quarts are required for a 32 by 6 truck tyre and four quarts for the largest low-pressure equipment. The cost is £3 3s. a gallon. After driving for about a mile, the material forms a film over the complete inner surface of the tube and makes an effective seal.

A simple pressure pump enables the liquid to be introduced into the tube in measured quantities. Advantages claimed for Puncturepriffe are that it does not deteriorate with age, does not affect natural or synthetic rubber, does not upset wheel balance, reduces running temperatures, diminishes the frequency with Which pressures need be checked and increases tyre fife, apart from the primary object of preventing punctures.

The compound, which has a base of glycerine, has been tested by a number of hauliers on vehicles of up to 15-ton payload capacity, and letters shown to "The Commercial Motor" confirm the maker's claims.
