[Healeys] 'New' 185R15 tire choice available...

[Eric (Rick) Wilkins]

That website doesn't give a lot of real specs on that 185/80 tire,  
but that 80 means 80% of 185. 80% of 165 is a whole different animal.

Basic math gives a diameter of damn near 26.7 inches for a 185/80 tire.

Factory manuals for the Austin Healey list 25.39 as the standard  
diameter.
