If the X was revolutionary in tyre terms, the XAS was the next great leap forward for Michelin. Michelin boffins worked out that different areas of the tyre have entirely different roles, so designed the XAS to reflect this. 

The result is a tyre with much-improved stability, grip and road holding and it has one of the best-looking tread patterns you can buy. There are twelve sizes in the XAS range with some sizes having a FF (Formula France) version with a softer, grippier compound.

This 155HR15 FF features that softer compound making it an excellent choice for: Lotus Elite; Porsche 356 & 914; early Volvo P1800; Alfa Romeo Giulia and Giulietta; Porsche 914; Citroen DS ID 19(Rear);  MG A; Peugeot 403 and 404.

This is a tube type radial car tyre.
