[6pack] Rotating tyres

[EdB]

Dennis:

 My own observations also show the right rear tire wears more, particularly 
on a rear wheel drive car or truck.  I had a flat tire recently on my Toyota 
truck RR tire, and was shocked to see the amount of tire wear in 31,000 
miles.  It was obvious that the left rear tire was not worn nearly as much. 
I was thinking of buying a tire tread gauge so I could take measurements of 
the tread on each of my tires.

The only explanation I have for this difference in wear is that the 
rotational torque of the driveline puts more force on the right hand rear 
tire.  When you accelerate hard, the first wheel to squeal or peel is the 
right tire.  And I know that I often accelerate a little bit hard while 
driving around in the city.

I cannot explain why your front right tire surface would wear more than the 
left tire except you may do more left hand turns under power where the 
vehicle weight shifts to the right tire.  The outside edge tire wear is 
usually a symptom of hard cornering, which is at least half the fun of 
driving a British sports car.
