[6pack] Tire sizes

[Rick Norris]

Thanks, Bob! After a few inquiries and web searches, I found that you 
are correct regarding there being more choices in the 70 series tires. 
There are a few 75's for passenger cars but most 205/75R15's seem to be 
light truck tires. Considering that the speedo will be nearly correct 
that'll be my choice.  Thanks again.
