Hi Guys- I was out for a ride today and had a rear flat. When changing the inner tube, I noted that there was a hairline split on the sidewall of the rear tire (pic below). The inner tube suffered a puncture at this location. I put on my spare inner tube, pumped up to about 70% of my normal 110 PSI, noted that it was not bulging through too badly, and safely finished my ride back home.
A couple of questions:
1) Is the side wall hairline split something I can somehow fix (no ideas here, except I read that I could fold a dollar bill on the inner wall to prevent the inner tube from protruding).
2) If replacing is required, I'm certain I should replace both front and rear tires. Any recommendations for brands/models? Current tires are Continental Grand Prix 4000 25 mm and I've got about 4500-5K miles on them thus far. I'd likely like to go back to 23mm, if replacement is recommended.
Cheers!
