Bought myself some new Gravel King tyres to fit, forgot how much of a mare they were to seal on the rims. Gone through 3 CO2 carts already lol. Stuck inner tubes in to see if that can help form the tyres on the rim and will try again. Also what’s a good sealant that I can inject through the valve stem ? Stans race sealant is great but a pain as it’s not for injecting !
