Tadeusz,
The XAS tyre is one of the original non-symmetrical tyres and the size you
mention, 180R15, is no longer made. I'm not sure if its replacement 180HR15
is still done other than for the specialist trade. Be very wary of the age
of the tyre if you have been offered some as it could well be some 25+ years
old. Check the 4 figure number impressed a recessed panel and note the shape
of the panel - an oblong, a square, a diamond or oblong with rounded ends
etc. This is a date code and the shape of the surrounding panel is a decade
indicator. You may find it as a 3 figure number which is a week and last
year number e.g. 067 is the 6th week (early February of either 1957, 1967,
1977 1987 etc. In those days it was not a requirement to date the tyres as
openly as they currently do and different manufacturing factories did
different things. If it is a 4 figure number e.g. 3486 it is the 34th week
(mid July ) of 1986 and if the memory is working it should be in an oblong
shape with half circle rounded ends.
It should be a good tyre to use on a Healey if recently made but if it older
than 5 years or so I wouldn't really want it if it were to be driven on in a
spirited fashion. Others may give a different cut off age and you cannot
disagree with that as the storage conditions account for a lot of unseen
degradation of the tyre rubber. If all you are going to do with it is
'potter around' it may be ok. If older and if it is a show car and not a
driver it would useable (but perhaps not concurs). If there is any sign of
cracking or dark thin lines on the sidewalls around the toe (where it meets
the rim) or tread - walk away.
Michelins are known for longevity and good wear but there is the trade off
with grip and on this tyre that is counterbalanced a little with the
asymmetrical tread pattern.
Regards to all,
Guy R Day
