Hi, Jeff,
Determining the effect a change in tire size upon speedometer readings was a
concern of mine when buying new tires for my Westy. If we accept the aspect
ratio of the straight 185R14 tire to be 82 as per the tire information shown at
http://www.hrps.demon.nl/jwbus/T2-tires.htm then mounting a 195/75R14 tire will
put the speedometer out by about .5% (i.e..: the speedometer will show your
speed
as .5% faster than actual) as per the tire calculation website
http://www.miata.net/garage/tirecalc.html.

BTW, I decided to go with Hankook 819 195/75R14 tires on my Westy. I've heard
favourable comments about them plus the price is reasonable ($92 CDN,
installation, balancing, valve stems included).
