Stans have a guide which shows which rims will run tubeless ready tyres anyway. It's worth going onto a site like Single track world.com and asking the assembled experts whether your current rims will take tubeless tyres. For example my lad's DT Swiss rims are not sold as tubeless ready, but we have them up and running using Stans tape, tubeless valves and sealant. No ghetto or rim strips required.
