The Michelin XAS is a truly great tyre. http://www.longstonetyres.co.uk/page...helin-xas.html i have had XAS on a couple of cars they are great for directional stability. If you have a bit of a sloppy old classic that wanders on motorways then these Asymmetric Michelin are brilliant. I have XVS which is a slightly later development of a XAS on this car, i think you can see the difference on the film https://www.youtube.com/watch?v=nKRf4Mp980Q

........
So from 1968 it was predominantly Michelin and Pirelli?
That figures because i think the CN36 http://www.longstonetyres.co.uk/page...o-cn36-n4.html came out in 1968
It is interesting about the Michelin http://www.longstonetyres.co.uk/page...helin-xwx.html because in lots of the current Michelin Classic tyre catalogs they list the XWX as coming out in 1970, but i also know that these tyres were fitted to the first Ferrari Daytona which came out in 1968. However i think when the XWX tyre came out they initially just called it the X
From Oct 1967. Definitely a different tread than the XWX...
"X" was Michelin's designation for 'radial' construction. The first radial was simply the "Michelin X". Later radials all had "X" in the model designation—ZX, XZX, XAS, XVS, XWX, etc. The official model designation in the price sheets of the standard whitewall tire pictured in the ad above was XWW.

Hi
I think in 1970 the 70% profile tyres with the XWX tread pattern were called XWX however i know there were 70% profile tyres with that tread pattern around but i believe they may just have been called X. I think that XWX tread design came out in 1966, but not low profile because that wasn't invented till 1968. https://www.borrani.com/michelin-tyres/xwx.html
This is an interesting articel thatt was written by a German magazine comparing the tyres thatt are currently available for Classic Porsche http://www.longstonetyres.co.uk/page...-porsche-tyres
