I’ve flatted on enough remote Colorado routes to have opinions about tires. Not just preferences — actual conclusions, reached the hard way. The wrong tire on a big gravel day doesn’t just slow you down. It strands you ten miles from the truck with a shredded casing and no cell service. So here’s what I actually run, and why.
Quick comparison
| Tire | Best for | Size options | Rating |
|---|---|---|---|
| Vittoria Terreno Dry | Fast hardpack and mixed gravel | 700x38c, 700x40c | ⭐⭐⭐⭐⭐ |
| Panaracer GravelKing SK+ | All-around gravel and light off-road | 700x35c–700x43c | ⭐⭐⭐⭐⭐ |
| Schwalbe G-One Allround | Mixed terrain, bikepacking, big miles | 700x35c–700x45c | ⭐⭐⭐⭐ |
| Teravail Cannonball | Loose over hard, rowdy gravel | 700x38c–700x42c | ⭐⭐⭐⭐ |
| WTB Riddler | Dry hardpack, fast rolling | 700x37c–700x45c | ⭐⭐⭐⭐ |
1. Vittoria Terreno Dry
This is what’s on my gravel bike most of the year. The graphene compound rolls fast without feeling sketchy, which matters when you’re descending a loose dirt road at 35mph and questioning your life choices. I’ve put a few thousand miles on them across high-desert hardpack and the chunky two-track stuff you find west of Denver. The flat protection is real — I’ve had things stab at them that should have ended my day and didn’t.
Where they fall apart: deep mud and loose sand. If you’re riding in conditions that wet, you need something with more aggressive knobs. But for 90% of Colorado gravel riding, this is my answer.
2. Panaracer GravelKing SK+
If someone asked me to pick one tire for every gravel condition I ride in Colorado, this is probably it. The SK tread pattern is versatile in a way that most tires aren’t — it handles hardpack without dragging, and it doesn’t get squirrelly when the road turns to loose gravel. The + version adds a puncture-resistant layer that’s bailed me out on remote routes where turning around wasn’t an option.
The trade-off is weight. It’s heavier than a race tire and you’ll feel it on long climbs. If you’re doing a gravel race and every gram matters, look elsewhere. For everything else, it’s hard to beat.
3. Schwalbe G-One Allround
The G-One Allround is for the kind of riding where you’re carrying three days of gear and crossing three mountain passes. It’s not the tire you race on — it’s the tire that doesn’t quit when you’re 60 miles in and the weather turns. The dual compound keeps rolling resistance tolerable, and the center tread actually grips on wet surfaces, which most “all-around” tires lie about.
It’s heavier than the other options on this list. If you’re not doing big loaded rides, there’s probably a better choice for your use case.
4. Teravail Cannonball
When the terrain gets genuinely rowdy — loose over hard, sharp chunk, rough mountain roads that blur the line between gravel and trail — the Cannonball is what I’d reach for. It has more aggressive tread than most gravel tires, which costs you some efficiency on smooth hardpack but pays back in grip and confidence when things get technical. Good choice if your rides regularly include chunky Colorado high routes.
5. WTB Riddler
The Riddler is a race tire at a price that doesn’t require a second mortgage. Low-profile tread, fast rolling, and a track record in the gravel race scene that speaks for itself. I wouldn’t take it somewhere wet or loose — it doesn’t have the knobs for it. But on dry hardpack it’s quick, predictable, and won’t embarrass you at the start line.
How to pick the right one
Three questions that actually matter:
What terrain do you ride most? Hardpack and dirt roads — go smoother. Chunky and loose — go more aggressive tread. If you don’t know, the GravelKing SK+ handles both well enough that you won’t feel like you made the wrong call.
What width fits your frame? Most modern gravel bikes clear 40–45c. Wider means more comfort and traction. Narrower means more speed. Run the widest tire your frame allows and your riding style justifies.
Are you tubeless? You should be. Lower pressure, better ride, far fewer flats. Every tire on this list supports tubeless setup.
Bottom line
For most Colorado gravel riding, I’d go GravelKing SK+. It handles everything without being the best at anything. If you know your terrain is mostly fast hardpack, upgrade to the Terreno Dry. If you’re regularly getting into aggressive terrain, the Cannonball earns its money.
