Of course I can change my own tire.
In some pretty harsh conditions to boot!!!!
While on the way back from the lake my cabin is on I had a flat and pulled over to inspect.
If possible I use my compressor to fill up a slow leak but this was a sharp rock in the tread and not slow.
So I replace the tire with the spare no biggie.
OH, did I mention it was -50 with the wind chill?
Another motorist stopped and asked if I needed help (I didn't)
