27 inch Road Bike tire buying guide

If you have a vintage road bike you might have 27” wheels, these were popular before the standard became 700c.  They left the market for new bikes sometime in the 80s with more expensive bikes changing to 700c the soonest. 

While they look very similar, 700c tires are slightly smaller than 27″ so tires are not interchangeable. 700c tire bead-seat diameter is 622mm and 27″ is 630mm. Please note that some vintage race bikes also used tubular tires, those have special rims. This article is for clincher tires.

If you need 27” tires the options are a bit limited, you will mostly find 27 1 ¼”.  Here are all the options I have been able to find.
