Technical FAQ: Taking care of unused tires | VeloNews.com
TL;DR- Bike tires will start to show signs of age after 4-5 years of storage. Not that they will suddenly fail, but they will degrade slightly. If you change both tires every 2000 miles (which is silly, I can get 5k out of a GP4000), you would need to ride 15k miles every year for 5 years to use up that stockpile. Not saying that's impossible, plenty of pros do way more, but why bother stocking up to world tour team levels of supplies for a single rider?
