I’m a Schwalbe fan in general, so if anyone would ask my recommendation for a decent gravel tire (for euro-gravel), I’d more than likely propose the G-One Allround in 40mm.
That’s probably the one I’ve done the most kilometers on, and also the only one I’ve bought more than once. But most of those kilometers were commuting. So I don’t know if it’s really my favourite gravel tyre.
Another tyre I’ve been positively surprised about, was the American Classic Kimberlite (40mm). Very tough and hard-wearing, still smooth rolling. But I wouldn’t buy it again.
I’ve had Hutchinson, Pirelli and Continental tyres - they were a bit meh (underwhelming rolling, less wear or puncture resistance…), and I never bought them a second time.
Right now, I have something new on, from Vredestein. And I think that might replace the Schwalbes as the go-to, and would also entice me to try other profiles from their portfolio. So I’ll describe that one here:
The favourite tyre: Vredestein Aventura Seta
The labelled width of it: 44mm
Measured width: 44mm on a 700c i26 hookless rim
The max clearance your frame allows: Surly Midnight Special prescribes max 700c x 42mm, but that seems very conservative, because my 44mm fits well, even with FD and mini front fender (Asssaver Mudder).
Any reasoning as to WHY this is your fave: Super easy to get on the rim and set up tubeless (no compressor needed). Part of my liking it might be because of those rims, they’re a quite new wheel set and my first carbon wheels - but the Vredesteins roll nicer than the Kimberlites that were on it before. It’s like I don’t notice any difference with the Schwalbe Pro Ones on my road bike. They’re a less expensive option than the more well known brands. I also feel more confident on them than the Kimberlites: they’re both tyres with a smooth center and knobs on the shoulders - generally, I don’t like cornering on tarmac with those knobs, but the Vredesteins seem to have a profile that allows faster corners on tarmac.
