Tubeless 40c+ knobbies?

Looking for nice, knobby tires that are tubeless ready and are between about 40-50c (i.e. 1.5-1.9")

basically, picture Specialized Terra Pro or Clement PDX in a 45c, tubeless variety.  That's the type of thing I'm looking at (or whatever I can get that is close)

Riddler 700x45 is marketed as a tubeless ready tire.

WTB Nano 40's are tubeless rated and fairly light.  I bought a pair this spring and tried them for a few weeks.  They were okay, but not inspiring in any way.  I wound up ditching them because I didn't like their pavement handling.  Too easy to lock up under braking and the knobs felt squirmy in hard turns on pavement.  The pair I bought still have a lot of life left in them.  If you'd like, I'll give them to you.  you just pay for the shipping.  I'm never gonna use 'em.

I replaced the Nanos with Bruce Gordon Rock'n'Road 700x43's and have been very happy with them.  They aren't explicitly rated for tubeless, but from what I hear a lot of folks run 'em that way and so do I.  I've had no trouble with them at all.  At pressures above about 35 psi the sidewalls will weep a little bit of Stan's sealant, but not enough to matter.  I still get a few months between sealant refills and I don't lose pressure to any noticeable degree vs. other tires.  They have a really retro plain jane look, but these are the most all around capable tires I've ever tried.  I ride technical singletrack and do 50+ mile days on mine.

the Riddler is more of a file tread, I'm kinda looking for a bit knobbier for this but I really like that tire, might put that on my other bike, thanks!

I am with you.  Totally *yawn* over the WTB Nanos. They're mismarked (38c Trigger Pros are at least as big as the "40c" Nanos) and I was totally underwhelmed by their cornering.  I suppose if you're going to ride in dirt in a straight line they'd be ok.

those Rock'n'Roads look pretty darn good.  Glad to hear you were able to work them tubeless

Specialized Renegades. If they are knobby enough. There are both 1.85 and 1.95 sizes that have been made over the years.

i have renegades now (2.3" version) and I love them for gravel and for semi-hard pack dirt but they go sliding in the mud.  I'm looking more for the mud(ish) type tires.  Thanks though, I do agree, Renegades are great, but looking for some more knobbage

I love my Nanos. 

Gravelking sk 40

Not sure I'd call the GravelKing SK 40 a knobby tire. Not smooth in a road tire kinda way...but certainly not knobby like a Nano. I actually switched from a Nano to the GravelKing because they weren't knobby.
