I have put successfully used the tube system on 29+, 27.5+ and 700c rims that are NOT tubeless ready rims, works AWESOME!!! I can highly suggest this tube plus armour system for rims that not tubeless ready. Now trying to use the tube plus armour system on rims that are tubless ready, don't even try it; it will be a waste of your time. The tube armour needs the deep channel of older rims to actually work, the flat tubeless ready rims don't leave space for installation. If you do get the tire mounted the system will warp the tire and ruin it.
