Bobby Lex said:Interesting tidbit on the "Chasing Lance" series on Fit TV last summer. Interviewed Discovery's chief mechanic (same guy used to be Eddy Merckx's personal mechanic). He has a "tire cellar" where he ages Lance's tubulars for his races. He claims they are best (most supple) when 7 years old.
Of course, those are silk tubulars. I don't know if the same principle applies to rubber compound clinchers.

I recently found some minty 12 year-old Wolber Neo-Pro SP1 in a bag in my garage. One day I'll glue 'em up and enjoy... until they get puncturedcapwater said:The "hooey" legacy lives on. Ride on boudreaux........

I have a set of Michelin Axial Pros which has hung unused and uninflated, for 5 years in my garage on a set of Mavic CXP21 rims. Would they still be good to use?
DiabloScott said:That principle doesn't apply to silk tubulars either... it's a bargeload of hooey. But that Julian guy from the Lance Chronicles was quite a character.
Temperature extremes, light, moisture, and ozone are what destroys shelved tires. Chuck's tires might be OK if they haven't seen too much of any of these, but 5 years isn't bad anyway - I'm pretty sure I've got 5-year old tires on at least one of my bikes.
Ozark Bicycle said:IIRC, the idea of "aging" tubies goes back to the days of the so-called handmade tires. The tread on these was not vulcanized after being applied to the casing, as the heat involved was thought to damage the delicate silk or Egyptian cotton casings. Hence, the tread was allegedly kinda soft and prone to cuts when new. Aging allegedly let the tread harden a bit prior to use. I'm not swearing that all of this was/is true, but it was the wisdom of the day. I don't know of any non-vulcanized tires being made today, so maybe this guy is just stuck on the old ways.

el Inglés said:tyres sent from the factory have a protective coating , as long as this remains intact the tyre should not deteriorate BUT once used they start to ago - if you fitted the tyres but NEVER used them then they may be ok but inflate and check for cracks , especially any seperation of the " tread " between the coloured bands ( the tread is extruded as one piece but does seperate with time , if it has then toss it in the garbage or use on the cycletrainer but not the road )
