I did a 13 minute tube change the other day from a puncture, wheel out & back in ready to ride (a personal record, yey), but most of the time I drive the wheels 3 minutes to the local tyre place & pay them $10 to change tyres. It's a shit job no matter what anyone says & I'd rather not sweat, swear & skin my knuckles to save $10. I use good old dishwashing liquid with just a smidge of water.
