[Spridgets] No real difference in tires

[Frank Clarici]

Specification  Sidewall  Radius  Diameter  Circumference  Revs/Mile

155/80-13      4.9in     11.4in    22.8in   71.5in        886
175/70-13      4.8in     11.3in    22.6in   71.1in        891

This is from a chart/calculator a lister sent me to check tire sizes.
Seems to me the 175/70s are a tad thinner and shorter than 155s.
But I do have 175s on the 58 and they sure look wider than 155s.
