I’ve been riding the Schwalbe Marathon Supreme in a 32-622 and 37-622 for the past couple of years. The Schwalbe is widely regarded as the best touring tire on the market (which also makes it an excellent commuting tire). It has a high thread count which makes it light and supple, it uses a state-of-the-art puncture-resistant layer, and it uses Schwalbes’ latest rubber compounds. The only drawback is its shockingly high price (~$75).
Often, the stock tires supplied on production bikes are not top-of-the-line. Such is the case with the Civia Bryant I purchased a few months ago. It came spec’d with Michelin’s City tire in a 32-622. The City is a relatively inexpensive (~$30) commuting tire with a low thread count (33 tpi compared to the Schwalbe’s 67 tpi) which makes it heavy and, at least theoretically, stiff. I have a set of Supremes I was planning on putting on this bike, but I have to say, I’ve been enjoying these Michelins so much that they’re going to stay on the bike until they either wear out or punctures become an issue.
On paper, the City should provide a harsh ride due to its low thread count, but I haven’t found this to be the case. In fact, I really like its road feel; it’s lively, surprisingly grippy, and it does a great job of muting road shock, even at my usual 60-65psi. It is a heavy tire, and I’m sure the rolling resistance is higher than the Schwalbe’s, but my commute times haven’t changed, so these are non-issues for me.
With flat season ramping up, the true test is coming. I also have to see how they wear over time. I’ll report back later this year and let you know how it goes. In the meantime, if anyone has been riding this tire, I’d love to hear how it’s working out for you.
