Vittoria Terreno Dry Tire, 700x40c

size: 700x40C (advertised), 700x38C (sidewall label), 622-40 (Vittoria's package label)...IRL 38.5mm on SL25 rims

tread pattern: Semi-slick center with knobby shoulders. Center has (very) slightly raised hexagons, shoulder has trapezoidal blocks

construction: 120TPI. 460grams, so lighter for a 40mm-class tire. Rated for up to 35-87PSI per the sidewall. Actually a TCS certified tire I believe. Result, is these are a bit of a hassle to mount (bead jack time)--but they really snap into the rim and will stay there even when flat--like a proper tubeless setup....unlike Panaracer ghetto tubeless.

Interestingly, has a bit of a "V" profile to the center of the treat when mounted, unlike others that are rounded.

performance on pavement: In wet or dry quite good. Spin up faster than more file-knobby center gravel tires. Don't spit gravel back at people in a paceline. Being semi-slick they due spray water a bit when wet. Being a smaller "700x40ish" circumference tire they have fewer gear inches-so you'll probably end up using one higher gear.

performance on firm and smooth gravel: As good as pavement. Confident cornering

performance on deep or soft gravel: In this stuff, all narrower tires suffer a bit whether knobby or not...and IMHO you tend to be more limited by tire width than tread pattern. In any case, it isn't very confident and can get squirrely.

durability: Running tubeless, seals well. Very wide range of pressures on the sidewall. Doesn't wear down in the center as much as knobbie tires when predominantly on pavement.

ride: Smooth, although it does have a bit of "Tie Fighter" tread air-noise when spinning. A nice quicker choice for harder ground. And with support for a wide range of pressures (sidewall says 35-87PSI!) can handle heavy loads like touring/panniers as well as rec riding on dry gravel/MMR or paved stuff.
