get accurate results.

In order to wipe out all these variables. a special machine bus been developed and patented in which conditions representative of rough roads, wet roads, roads cover- ed with dust, quick acceleration, wheel spin, high temperature, can all be reproduced and controlled.

The relation between abrasion, or wear of tyres, and slip, which, of course, is always taking place when tyres are running, can be quite accurately determined.

..

Approximately, the rate of wear increases not in direct ratio to the slip, but rather as the square of it up to values of about 25 per cent. About that value, the relation is approximately linear.

As showing the accuracy with which the machine and road results can be compared, samples of the actual trends of tyres were made into test wheels while the real tyres

Six years ago Tom Humber built bone-shakers in a Nottingham shed; to-day, the works of Humber, Ltd. in Coventry, cover upwards of 25 acres of ground. The Diamond Jubilee has come and gone, leaving behind it a record of which any manufacturer might well be proud.

Other teats, on "the road, showed that one tyre on a car ran 8.400 while another, used during April, miles during December to March May and June, ran only 6,000 miles. Another test, in which two exactly similar tyres were run at the same period on the rear wheels of two cars, of the same type, showed that. the rate of wear on the one rup on rough roads was twice that of the other, run on tarinac.

is

Two tyres were again run on the rear wheels of a touring car and a sports car respectively. The tyre on the touring car ran for 5,000 miles under average conditions, but the other tyre was worn to this aame extent after running only 335 miles at an average of 90 m.p.b. on a racing track,

Considering fast touring speeds, the rate of tread wear on tyres which average 50 m.p.h. was found to be about 0.17 m.m. per 1,000 miles and this is about twice the rate of wear of tyres run at an average speed of 30 m.p.h. Above 05 m.p.h, the increase in wear is very rapid.

Excessive toe-in has a very bad effect and it has been found that a toe-in of an A of an inch should not be exceeded, otherwise the tyre will not last its full life. A tyro run with a toe-in of inch was nearly worn out after 3,700 miles. Another with a toe-in of 1-10 inch has run 9,000 miles and is not yet nearly worn out."

Tents made for wheel ship with a motor cycle combination showed that on cross country run at normal speeds there was a total slip of only 1 per cent., but on a rough road a short run at 02 m.p.h. gare a slip of th. per cent. By fiercely engaging the clutch for rapid acce- leration a slip of 10 per cent. was obtained. In a similar "gataway," measuring the slip on the first za yards only, it amounted to the very high figure of 48 per cent. If the slip be doubled, four times the amount of tread rubber will be worn away.

It is of intercat to note how the wear of tyres varies according to the season of the year, partly due to the temperature and partly due to the wetness or dryness. For in- stance, the rate of wear of a Jargo quantity of tyres in July of three successive year was 8/10 m.m, per thousand miles, while in January of the corresponding years, it was only 6/10 mi.m.per thousand miles...
