Put them back on the bike before you sell it and say there’s loads of life left in them 😆
This is usually my tactic, stick the worst ones on any bikes that’s being sold.
But I still end up with a box of part worn, but not too badly, tyres.
Non-tubeless annoys me, OK so ~70% of tyres work anyway, but who is still buying the non tubeless tyres that don’t work with sealent? E.g. continental still make a budget 29*2.2 Race King (that’s actually an alright tyre IME), but it doesn’t work tubeless. Whereas a Schwalbe Racing Ralph does. So I end up with a pile of tyres “well I might put them on a commuter someday”. But I won’t, becasue no one wants a puncture at 7am on a wet Tuesday morning in November.
It’s like rims, almost every rim from £500 bikes upwards is some variation on tubeless now, so why aren’t tyres?
Is there’s a significant cost involved in molding a slightly different shaped bead? I kinda get that the tyre ends up a few grammes heavier, but then the people who care about weight, aren’t buying mid range tyres.
