I had tire troubles today too. Found a couple of goatheads. The big one was near the sidewall so I didn't touch it and held my breath. The other broke off and probably didn't go in deep enough to damage the tube. I rode the six miles home, pulled the big one and whoosh, flat tire. Luckily, it was the front so easy to change.

Performance always has tubes on sale so I have a good supply.

It's the second tube I changed this year, my bike sat in the basement all winter with a flat back tire so I had to fix the flat before my first ride of the season.

I hope I'm done for the rest of the season.
