suzuki250 Posted January 21, 2022 Report Share Posted January 21, 2022 Does anyone know if inner tubes have a shelf life? I’ve just found a few new boxed ones from the 90’s are they any good? They look ok, boxes are a bit tatty! Quote Link to comment Share on other sites More sharing options...
Nishijin Posted January 21, 2022 Report Share Posted January 21, 2022 Easy way to find out is pump them up ‘hard’ and leave them for as long as you can tolerate. There’s a risk (if improperly stored) of cracking, maybe the valve leaks now. I’d just pump them up and leave them hanging. If they are still pumped hard a day later it’s okay for emergencies. If they hold air for a week then it would be worth using. 1 Quote Link to comment Share on other sites More sharing options...

still trying Posted January 26, 2022 Report Share Posted January 26, 2022 If the rubber shows no signs of degradation powdering etc, and holds air, then they would be worth using. Quote Link to comment Share on other sites More sharing options...
guy53 Posted January 26, 2022 Report Share Posted January 26, 2022 I think it depend on the conditions they where stored. Guy 1 Quote Link to comment Share on other sites More sharing options...
