HOW TO GET GOOD SERVICE FROM
MICHELIN TYRES
We can tell you
Keep tyres pumped up to correct pressure for the load they have to carry. what this should be.
When tyres are under inflated there is con- tinual internal friction between the foundation cord and the rubber, causing overheating of the tyre and consequent rapid deterioration,
Water can also enter causing rust, resulting eventually in the rims having sharp edges which cut the walls of the tyre near the bend.
Most cars in Hongkong run or under inflated
tyres with the above disastrous results.
Have your wheels examined front and rear for trueness and tracking alignment. If they are at fault in this respect the trend of the cover is subject to a grinding aélien which quickly destroys the cover.
Keep tyres free from oil and grease.
Start and stop gently and take córners slowly.
Lastly-buy MICHELIN tyres from us and follow the
above advice and tyre satisfaction is assured.

Don't call it "double:clutching" thero's nothing of that about it. It's "double-do-clutching " the clutch romains "singlo" in pite of so many "correspond- onta."
But what is double-de-clutching anyhow? Well, it's the perisct way of making a goar changa from a bigh to a lower gear. How to, explain it ? Rather difficult in so many words-but let's have a shot..
