Hi team
Pirelli have just made a fresh batch of the 175/70R13 Cinturato CN36 which is the best low profile tyre for loads of classic Ford. Specially Escorts
https://www.longstonetyres.co.uk/175-70vr13-pirelli-cinturato-cn36.htmlWe do have the 155R13 Pirelli Cinturato CA67 that was fitted to the road cars as standard. and yes as a road tyre that proper period carcass of the Cinturato in the 155R13 size makes it the nicest tyre for road use. However if it something a bit more sporting you are looking for then the 175/70R13 CN36 will give you more grip while at the same time handling nicely as well.
On your classic Ford the CN36 will handle muich better than a modern tyre carcass.
