Michelin CUP shelf life...

[funtime]

As above, providing they've been stored in a garage out of direct sunlight would a pair dated 40th week of 2003 be alright? matched up with a pair of new cups on the other side of the car (one front and one rear) ?

Actually as I type that it sounds daft so I will await a flaming and a slapping from Shimmy :gayfight:

Should be ok when warmed up fully - i used a pair of 'Shimmy Special' fronts on track last year and they were fine. (mfg 2003)

Ideally though you should have tyres of similar type/age on the same axle...

Ok cool, think I'll avoid though like you say each axle should have the same! :smokin:

for anyone that wants them, there's one brand new front and rear for £350 on pistonheads :thumbs:

Generally speaking all tyres have a shelf life of 6 years whether they've been stored correctly or otherwise.

Rubber deteriorates whether you store it correctly or not.

Personally I wouldn't risk my car for a couple of hundred pounds.

Well said Tom and absolutely correct :thumbs: I wouldn't fit six year old, ordinary road tyres to my daily donkey let alone to my :smt055 CSL.
I'd hazard a guess but if you had a blow out due to sudden de-lamination and consequently caused an accident, damaging your car and maybe others, the Insurance company could use this as a reason to invalidate the policy. :whistle:
