RE: Profiles of tyres

[spamiam@comcast.net]

Well, I recently bought some 165-15/70 tires for my TR4a and the speedometer is 
just about perfectly calibrated, so the profile must be very close to the 
original RADIALS that were on the car.  The speedometer calibratio is 1152.  If 
yours is 1184, then the reading will be about  32/1152 (about 3%) low (if 
everything is otherwise about the same as my 4A).
