Quick follow up after a good ride yesterday, I can tell right away these are excellent all around tires. They make you want to keep going after your done. These tires are smooth and live up to the marketing description from my limited time on them.
My take on these are from an enjoy the ride point of view. I didn't check my avg speed or try and race anyone, during the ride. I was going plenty fast and simply enjoying the scenery. All about the ride.
I put 33 miles on them with 15 paved, 8 gravel, and 10 single track. This is a good mix of what I would encounter in any sort of Florida adventure I might partake in the future.
On pavement they hold their line well and once you spin them up they roll on without any extra effort compared to semi knobs I have used.
On gravel which there are infinite varying degrees the sawtooths were smooth and I wasn't constantly searching for a line, just cruising along with whatever came my way.
Offroad on singletrack I was impressed and surprised how well they handled sand which is as good as or even better than mso 36 semi knobs I have. I live in Florida and we have lots of it. Once my confidence in the tires built up I was having a blast in the dirt. Even wiped out on a sandy leafy sweeper turn (my fault, to much speed on entry and I was in the drops front wheel dug in at apex wouldn't turn and WIPEOUT)
No complaints at all great tire for the money, and I doubt there is a better all rounder out there.
For me this will be my default tire for awhile and I'll check back after 1000 mile to relay wear and reliability concerns if any. They have blackbelt protection and strong reinforced sidewalls for high carrying loads for lugging gear,panniers etc.
I had about 10lbs of carry weight during ride and used 50psi as a baseline on paved then adjusted psi according to conditions.
When mid summer hits I'll see how I feel about these because the brutal heat can take a toll on you here. I think I finally found a winner in these as an overall great tire. Are there better pure gravel tires? Sure but this is more than a gravel tire.
For now I give them 5 out of 5 stars.
When the pavement ended I ran into about 20 yards of this and let out about 3 bursts of air front and back.
Headed to the dirt
Short steep hill loose shell,gravel whatnot, I lost a little bit of traction going up but would have with any tire I own.
First sand I squirreled my way through
More sand and by this time I had lowered psi to about 30 front 35 rear and was blasting through.
Chickened out at washboard I didn't want to beat up my rims ,it's all roots in there and twisty turny.

After a few more easy rides I noticed I am in the drops a whole lot more for some unknown reason and more comfortable too. Maybe due to the tire extra height? I dunno but it is a very nice attribute of these Sawtooths.
Also on my regular 15 mile fitness routines I lost very little overall speed compared to my 32 c skinny tires not enough to matter to me.
PSI @50 is on the stiff side and will start to experiment with lower pressures on the road. These tires bring back that mountain bike feeling.
Side effects include but not limited too while riding these:
Uncontrollable laughter in the middle of nowhere at anytime
Not bothering to look at a map before getting lost
Not looking at your cell phone, gps
Packing for the apocalypse while out for a quick ride
Thinking your on a 29er
Forgetting what time it is
Not taking gravel riding serious
Guilt about paying more for supposedly better tires
Starting a friction fire in the wild
Trying to find the north star
converting psi to bar
