If I could recommend one thing. Use a lot of soapy water to clean and wet the outside bead of the tire. The suds will help slip the tire on and when it dries, it will give a good clean seal. If you can get a tire to seal with just soapy water and some air, it will seal no problem with some Stans. Do not try to seal a dry or especially dirty tire. Just a word to the wise. After you put the Stans in, rub some soapy bubbles on the bead and then do the shake thing they show in Stans video. Good luck. Flows are the easiest to seal I have ever used ...by far. i do use a 50/50 mix of Slime brand and Stans. The Slime keeps it in a liquid state longer and the Stans does a better job of sealing the tire to the rim. YMMV.
