the high profile 5.6 tyres yield similar numbers, but...
The above data is for 175 70 R13 or 205 60 R13 as both are within
several milimeters of theoretical circumference.
This data was specifically compiled using the 205 60 HR13 MFGr data,
and empirical data I took for my car. The 175 data just goes along for
the ride.
