Standard fitment for the Samba is a 135SR13 radial tyre, with optional fitments of 145SR13 or 165/70SR13.
The Samba is the last Talbot, conceived as European/World car in the supermini class, it was based on the Peugeot 104, and was a fairly conventional car. Especially as it replaced the vaguely unusual RWD Sunbeam. It didn't really attract buyers in the UK, despite there being a convertible.
