Had my first flat tire on Saturday. Looks like I rolled over a piece of ceramic tile in a parking lot. It was a gash and not a hole so I bought a new tire yesterday. Then today I went to work in the yard and discovered a flat tire on my 2 wheel wheelbarrow. Looks like the tire just wore out. Prices for a replacement range $40 - $50. I can get a new one for $100. Looks like a trip to Tractor Supply on Friday or Saturday.
