Which tire would you recommend, max 38mm as I'm using it on a road bike, that's the absolute maximum with additional tire clearance. I need something with a little bit grip in order to ride on gravel, but the rolling resistance is the most important factor for me, thanks in advance for your support

35mm TerraSpeed is probably the best compromise of super fast and a little grip.
Cervelo P5 Disc (2021) 9.1kg
Factor Ostro Gravel (2023) 8.0kg
S-Works SL8 (2023) 6.3kg

*weights are race ready, size 58/L.

I'd go for 36mm Challenge Strada Bianca or Rene Herse Bon Jon Passes in the Extralight compound if you want the weight weenie option.

Or just Gravelking Slick, Semislick or SK. The Slick is almost as fast as the Herse Bon Jon EL at less than half the price, check out BRR

How much tire clearance would you risk as minimum 😊

I have Zipp's G40 Xplr tires to go on 303S, but wanted to try something with semi slick thread...
I like at least the looks on Vitoria tereno zero, but they say only on hooked rims, mine are hookless;
Anyone running them hookless???

Another possibility is Specialized PF, but again don't think they/Specialized/ recommend mounting on hookless rims... Anyone thoughts, experience??? Not sure how well they would be when cornering on road?

Third option is GK SS, but multiple people say, super hard to mount and traction is questionable...

Basically I want to try a tire, which isn't a full not slick to be on my gravel bike/only one set of wheels, so it's gonna be inconvenient to change tires often/...

Something that rolls very fast on pavement it's some capability Off road, has to be mounted tubeless and hookless, hold air well and around 700x38C.

Thanks for ur time gents...

I'm planning to put Challenge Strada Bianca on my 303s' next. Challenge customer service confirms that they are tubeless compatible from 33c upwards.

On a side note, I've briefly tried the GK SS and never again. Horrible front-end handling and I'm not the only one saying that. YMMV depending on your bike and how sensitive you are for these kinds of things. Buyer beware.

1) I wouldn't worry about hookless rims here. None of these tires have super thing sidewalls.
2) THe Zipp G40 tires are relabeled Hutchenson Toureg (Mavic/Pirelli) FYI, they probably roll like a https://www.bicyclerollingresistance.co ... i-gravel-h
3) If you look at most tests, you'll see the Conti Terra Speed would be the way to go if you're on a deformable dry surface and they also have a good sidewall. The Panaracer GKs and SS are also good. https://www.bicyclerollingresistance.co ... el-reviews The Pathfinders are good if you need some sharp rock protection (shale).
These two are only going to be 4w faster per pair. Unless you go Strada Bianca Pro or Rene Herse Extralight something or Schwable Pro One 34c (new), you probably won't be any faster. If you're off road, even perfect hard dirt trail, tire width makes a huge speed difference. The aero cost of the knobs is about 1.5w per size incriment from 25c (28, 32, 35, 38/40, etc) and the mini-knobs coase about 1w at 30kph - so there's not much of a cost for the knobs, but the size costs about 6w (3kph ish) . When you get into the bigger knobs, the rubber needs to be harder to support the knob, so the tire is slower.

FWIW, I've run Schwalbe/Conti/Maxxis hookless in this space without issue. From what I've seen the issue is pretty limited to narrow rim lip (aero) road tires with super thin sidewalls. The smaller tire puts a lot of pressure on a specific spot if hit a bump while cornering. This all happened becuase Evne was playing it fast and loose with their testing. They probably just tested all the tires with a tube in them for speed. Also, the Zipp's use a 2mm rim edge (23mm int/27mm external)

Thanks to all.

BTW anyone had any experience with Specialized sawtooth 2bliss?

They look promising, they come in 38 and the gripton compound rolls really well.
