Sorry, only just saw your reply;
Amazon links getting messed up. Search for “Reehi Large J Garage Hooks,Steel Garage Tool Storage for Organizing Power Tool,Laddy,Bulk Items (4pcs)”
I would have liked to find a way of cutting them in half and using one half per hanger, but decided life was too short and just bent it flat in the vice! Depends a bit on rim as well as tyres, 2.4 with deep section carbon aero rims would be more of a struggle!
The tyre in the middle of my pic before, the dirty one, is a 2.75in Dirt Wizard on Stans Flow. Would you believe it, it’s actually 2.75in exactly across the shoulder knobs. There’s space for more in the hook. prob 3.25, would be the limit, less with a taller rim, maybe more more with a very flat rim profile like stans Hugo.
