Get the wheels off your bike and start practicing changing them..

If you rely on gimmiks and cans of wonder gunk...
you are setting yourself up for a long walk or push...

not as hard as it looks....But the first 6 times you will be thowing the levers..

I find it harder to get the wheel out and in the bike than change the tyre..
but I do 6 or 8 a years.. have done for 30 years..

carry one 19" tube... it will fit into a 17" wheel & stretch over a 21" rim..
