RELATIVE TYRE WEAR

WHICH SIDE GOES FIRST? The fact that tyres on the left hand side of a car wear out faster in proportion than those on the right-hand side often puzzles motorists, says a tyre expert in the "Goodyear News.” The popular supposition that this wear is caused by turning many corners to the left is incorrect. The fact is that the increased wear is actually, caused by the pitch of the road, which throws more of the car on the left side than on the right. The crown of the road from kerb to kerb is far more important in determining the sequence in which tyres normally wear out —left rear, right rear, left front, right font —than is gutter wear and abrasions from grinding off on pavements. The slope of the road causes the left rear tyre to carry more weight than the right rear tyre. Thus the left rear wears the faster of the two. The left front will also wear more rapidly than the right front, for the same reason. However, as the right rear wheel receives a driving pull, while the left front does not, it will wear the faster of the two. Under average conditions the left rear tyre wears out first, and the right front last. To secure uniform wear from a set of tyres, change them around about once a month. Particularly is it important to reverse the rear tyres. After the rear tyres are worn down, reverse them with the front. MOTORISTS’ “I WILLS” COMPLEMENT TO “DONTS” Motoring authorities have been giving motorists the “Don’ts” for so long that this new series of “I Wills” is a surprise. Here is a new creed: I will obey all traffic laws. I will have my car in perfect mechanical condition to avoid accidents. I will keep my car under control at all times. I will be on the lookout for children and heedless pedestrians w r ho run on the roadway without warning. In the event of an accident, I will stop and render assistance. I will observe conditions of the roadway which make driving dangerous and support efforts to have such defects remedied.

I will interest myself in legislation designed to benefit motorists, and will do all in my power to prevent enactment of unreasonable restrictions. I will warn others who violate the law, and report their violations if serious. I will co-operate with all officers of movements that have for their purpose the safeguarding of life, the furthering of better roads, and the defeat of unfair laws. And I will conduct myself and drive my car as to keep the car in the good repute of the community.
