For the first inflation I always use my Joe Blow pump with tank - infact it’s my default pump these days. You pump,the tank up and connect to the valve, turn the wheel and the air all goes in very very quickly.

Thanks for this, Ive never seen one before. Looks like the solution. I didn't think a 12V car tyre inflator would cut it.

When I picked up my new road bike it came tubeless ready with 30mm Schwalbe tyres. The mechanic said could convert them to tubeless so I agreed and watched. He inflated them with a compressor.
Six months on (and no punctures) I decided to replace the tubeless sealant as recommended. Just as well I did because there wasn't much sealant left, I presume it had dried out.
However, no matter how hard I tried, I could not get the tyre to 'pop' onto the rim using either a track pump or blast of CO2. I tried using sealant and water as a lubricant to help but it still wouldn't work.
It seems the only way to get the tyre to seal onto the rim is to inflate the tyre with a huge burst of air like the mechanic did with a compressor. I don't have an industrial compressor and am not going to buy one just to inflate my tubeless tyres every 6 months! Has anyone got any suggestions? Would a 12V car tyre inflator provide a big enough surge of air?
Thanks
