Tire contact area

["Nick Pashley" <NickPashley@xxxxxxxxxxxxxxxx>]

I agree with Mr Roman, here is why..........

If we went to the extremes......  It is plain to see that with a tyre the
same diameter as a golfball, the contact area would be a lot less than if
the tire was the same diameter as the world.  OK, as far as going from a 16"
wheel to a 17" wheel, the difference is smaller, BUT nonetheless the
difference is there.  Whether this difference will be noticable in terms of
tire life remains to be seen, expecially since these effects are probably
thrown into insignificance compared to the effects of the amount of hard
acceleration and hard cornering that the car does..........
