Have ridden 4,700km in the seven months Apr-Oct. I have two sets of wheels, one with 45 Riddlers, and one with Panaracer 38 slicks. I switch the wheels depending whether I am going on a mostly road or mostly gravel ride, and it's probably an even-ish split between the two, so let's say 2,000-2,500km on each.
I tend to ride a 100km+ ride each weekend, plus 1-2hr rides mid-week.
I also ride MTB trails and downhill, and until Apr also rode road, so have a wider perspective than gravel, and am not including those distances in the 4,700km.
I was expecting to dislike the Riddlers, which was why I bought the 38 slicks, too, but really they are very good. Strava shows that terminal velocities on identical long downhills are a couple kmph slower on the 45 Riddlers than the 38 slicks, but overall section times barely vary. Overall ride times are more difficult to pin down, as I rarely do the same route on both wheelsets - one biases road and the other gravel. My Strava asphalt PRs are mostly with the 38slicks, though there are some on the 45Riddlers. My Strava off-road PRs are probably all on the 45Riddlers.
My rear tire is now bald in the middle, and I punctured catastrophically needing a Stan's Dart, hence I am here looking at tires. I will likely buy the 45Riddler again, unless I find more puncture proof or colored versions that might change my decision.
The front tire also needed a Stans Dart recently. In both cases the puncture was in the tread area, and looked more like a clean split, like a table jelly or something made from silicone splitting. There appears no effective help from threads or puncture breakers, so if I find a version promising those, I will grab it.
I'm seeing the Raddler (not Riddler) out the corner of my eye, and will investigate further.
[edit - ah-ha! - I found the Riddler SG2 and Raddler SG2. Perfect!]
