Oooh, goody..how to figger out height (or rolling diameter as Al mentions) from 
the tire specs...this is fun!

Given the two sizes,205/70 and 195/75....

The first number is the tread width in Millimeters. The second number is the 
"aspect ratio", which is derived as the percentage of height the sidewall has in 
relation to the tread width.

For the 205/70, the width is 205mm and the sidewall height is 70% of 205mm, or 
143.5mm. For the metric impaired, that would be 5.64". So, add (2 x 5.64) to the 
rim diameter to get total height.

Similarly, the 195/75 is 195mm wide and the sidewall height is 75% of 195mm, 
which is 146.25mm, or 5.75". In this case, add (2 x 5.75) to the rim diameter to 
get the total height.

Looks like the two are pretty close in height.

Just my $.02 worth...

My local costco has this tire 2ply sidewall, 4ply tread, C rated, max pressure
50PSI at ~60$ each.  

The questions for net.vw.wisdom are:

1.  ennybody running these shoes?  How do you like em and on what bus are they?

2.  What would the rolling diameter difference be between 205/70 MXL$$$ and 
    195x75.  

The intended use is a mostly on road syncro westie.

Derek?, Harry?, Syncrohead? whats the poop?

It is my understanding that the 205/70 MXL reinforced is NLA, BTW.
