I've used these tires extensively and they are by far the best combination of a durable, fast-rolling, excellent traction tire out there in the 700x category. Obviously your experience may vary from mine. That being said, the FlintRidge are my winter commuter (hit some trails on the way home) tire, a decently go-fast R U G G E D race tire, and excellent for cruising around town when there's lots of puncture items on the road.

700x40 and 700x45 are great choices.

This was my second, and likely last pair of Flintridge Pros. I've raced on them and liked their high profile and loose surface and pavement handling. I did feel my rear wore out faster than my old go-to's WTB Raddlers but I likes the bigger/higher volume. My last Flintridge Pro (rear) blew a large, unfixable hole on a rocky downhill but I attributed that to it being near the end of its tread life. On my third training ride of my new replacement Pro's, I ran over some unavoidable glass bits on the pavement and it punctured in 3 places. These were just shards and not what I would call super sharp. I never punctured on my Raddlers, so I would say that the advertised 'robust puncture protection' is just average, or below average. I'm done after these wear out and going back to WTB.

Had 2 flats in 2 days - glass on roadway that vehicles forced me into. Decided to sweep up the road and get new rubber. Replaced 2 Bontragers that sucked anyway. Inherited those when some crack heads stole my ride and swapped out the Conti slicks for some bizarre reason. Recovered the bike with a few other titanium missings as well but glad I got my Klein Rascal back.

Anywho yeah these are pretty decent except the thin sidewalls. Guess they want to shave weight but that's not me concern as I am far from a skinny pants hipster. I think you will be pleased plus they are quite cheap at BTD.

I restore donated bikes and give them away. I recently received two old three speed bikes in good condition, one was a Schwinn. I couldn�t find any ISO size markings on the old tires, just a reference to a Schwinn S2 rim or something. I purchased 4 tires thinking they could satisfy the other bike too (Free Spirit Brittany - like an old 26x1 3/8 tire as well). These tires didn�t work for that bike, which required ISO 37-590 size tires.

Mounted these on the Schwinn bike just fine, pretty true to round and an excellent value. I�m glad they are still available for these vintage bikes.

Fun fact: Both these bikes were shot in a flashback to �60�s scene in a film coming out next year.
