For a long time I've also taken mine to the tyre shop, when I need a new one I ride over, but with a flatty I have to take it, like today, as I picked up a pop-rivet a couple of days ago
. I reckon this time I'll go on the Gutzi and get a tube and do it myself, not to save money but just for the practice, but as I said above I might ride over after for a balance check.
Probably doesn't need to be said but; if you fit it yourself don't use levers for fitting- use a rubber mallet, should go on easy using methods mentioned elsewhere.
I need the practice because a few years ago on a Thursday, I was 400k from home middle of nowhere just getting dark, and had to be 40k other side of home for 7am next day. Luckily I saw lights ahead which turned out to be the roadhouse that I thought was another 30k up the road. I managed to limp there and ripped the wheel off when a guy offered me a lift 300km south but closer to where I could catch a bus the remaining 150km east and sort it out (needed a new tyre anyway). He was doing a return trip a couple of days later, so did the same trip in reverse (order), lucky it was a long weekend.....If I'd had levers and a patch kit I could've maybe done an emergency repair- and just add air.
