Speedometer off?--spider tires/wheels

One thing you don't want to forget about tire sizing is that the aspect RATIO 
is the percentage of the tread width. 60 series tire side wall is 60% of the 
tread width. 70 is 70% , and so on. For instance, a 175 / 60 / 15  (105 mm 
side wall) would be shorter than a 225 / 50 / 15 (112.5 mm side wall)  With 
the tire size calculator you can use different tread widths and aspect ratios 
to come to the right height.  Hope this helps you to find exactly what you 
need.
