KOR-KER.

A SUCCESSFUL DEMONSTRATION.

On Friday night Messrs Cassrels and Le Quesne gave a demonstration of the effectiveness of kpr-kei] puncture cure. The car used was owned by Messrs Nicholas, Ltd., the tyres of which had been treated with kor-ker about a fortnight ago. Four-inch spike nails were driven into the tyres and withdrawn, and .although this performance was repeated upwards of a dozen times the tyre still .remained inflated to the standard it was before the operation commenced. There is not the slightest doubt that kor-ker is a defence against punctures and porous- tubes. It is a compound in the form of a clean, dry powder, which is mixed with pur? water to about the consistency of thin porridge and installed through, the valve into the inner tube without removing the tyre from the rim. In a short address about kor-ker, Mr J. Cassrels said: It contains a preservative to keep the tubes elastic and to preven* the drying-put of the rubber which causes them to crack and develop leaks. It does not interfere with vulcanising, and will never go into solution, dry out, gum, harden, ferment, or become sticky. It contains no ingredient -that can injure- the finest fabric. Kor-ker occupies only about 6 per cent, of the air s pace and in no way affects the resiliency f the tyre. It has been in use for the past six years in almost every country in the world, and is-.recommended as standard equipment by some of the largest automobile and moter cycle distributors. Chemists and tyre manufacturers hav.e analysed and endorsed its use. Kor-ker seals punciutes instantly without stopping the car,. Any puncture up to the size of a 4-inch nail will be sealed "on the go.” Vith the turn of the wheel the ho c is sealed permanently without loss of air pressure. It is not claimed that Kor-ker will seal rips, cuts, or blowouts, but it will not interfere with the vulcanising of them. When the wheel is in motion Korker spreads out. in a coating about the thickness of the tubb and when a puncture occurs the .air instantly forces Kor-ker into the hole, where it forms a permanent air-tight plug.,

g It keeps tyres hard and finds and seals the porous places and small leaks in ■the tube, and, by keeping your tyres hard, removes the cavse of over 60' per cent, of all lyre troubles (under inflation). It preserves .rubber and keeps tyres copier in summer and prevents the oxidising effect of constantly adding new air. It also removes the danger of deterioration from oil which is carried into the tube by ai r frpm the pump. It is claimed that it increases tyre mil,eage, and greatly increases the life of the tube.

From what we have seen of its works we can confidently recommend its use to all wheelmen.
