I do have an on-going problem with goathead punctures, so am always looking for a tire that rolls as good but is somewhat resistant to punctures. For those of you not living in the Southwestern United States, let me tell you how awful goatheads are. They are from an invasive ground level plant that reproduces at a prodigious rate. The seeds are built like little caltrops that puncture just about any tire I've found.
I've tried the amazing 700c Grand Bois tires, and while they roll wonderfully, they are just too delicate for my needs. I really do appreciate how low their rolling resistance is. Some QC issues as well I found.
In my quest to find the next best thing, I was able to borrow a set of Schwalbe Marathon Supremes (thanks Doug!). I found them to be about the same weight as the Paselas (Paselas have less wear, so I'm extrapolating that they're about the same weight when new).
Both tires pump up to near 34.5mm at 35psi.
So same weight, same size, but they don't roll the same. The Pasela seems to be able to roll further when I'm coasting down a known road. Not hugely, but enough that I can notice it. The Supremes also feel heavier and clunkier. That's on the same rim, same bike, same pressure, same roads. Yes, subjective seat of the pants speedometer. I'll gladly refund any subscription money you've paid to this blog if you don't like those results.
And then there was the puncture!
This happened the same weekend that I mounted the tires up. Maybe within the first 20 miles? Anecdotal of course, but it seems like the puncture protection isn't all that much better than the Paselas. Perhaps because the Supremes were fairly worn? With full tread they should be more resistant, but also a bit clunkier then what I felt was already sorta' clunky-chunky.
So, long blog short, I'm going to keep up withe the Paselas for a while longer. The Supremes would be great tires if you value long wear and probably improved puncture resistance. While I like those things, I want something with a bit less rolling resistance, but not too fragile. For now the Paselas meet that goal! Will keep my eye on the Challenge Eroica, though. I bet they will be a bit on the delicate side, similar to the GBs.
