What's the largest tire you can fit on a 29" by 24.6 mm rim

I have a Turner Sultan with a Fox 34 fork. Tire would be for the front. I am currently running a 2.40Arden. Tempted by the new Schwalby 2.60 Nobby Nic. I have plenty of fork clearance.
 
Is that your inner width? More than likely not an issue at all. I have a 2.5" Minion front on a Flow EX(25.5mm inner) so you're talking about 1 mm difference in width of rim from mine and an additional 2.5mm in tire width. Before the Flow, I ran that same 2.5" Minion on a ~18mm rim with no issues, with a little more sidewall flex, so you definitely don't have anything to worry about if you're thinking the tire would pop off the rim under turning or something.
 
I just wondering if I can squeeze the sucker on. Rim is a Stans ZTR Arch EX. Diagram on the website shows 24.6 outer edge and 21 inside of that.
 
Generally, wider is better when it comes to tubeless because there is less of a chance of the tire folding over and burping/falling off the rim. The best place to ask for recommendations would probably be Schwalbe. It will mount for sure, and hold air for sure. The only thing nobody can really guarantee you is what will happen under hard cornering at your optimal tire pressure. You don't want to get a super wide tire and need to run it at high pressure to prevent fold over, because that just takes away from the luxury of low pressures on wide tires.

Here's another article about a 2.5" tire on a 21mm rim. That's pretty close to your measurements and they had issues at fairly high pressures to what I run, but Stan's also does make some of the best tubeless wheels so you may not have any issues.
 
Something to think about especially considering where I ride I am usually running 20 pounds. Many thanks.
 
One issue I noticed with only a 2.40 is its already looking like the diagram on the right shown above. I may consider a wider rim first. Great to choices...
 
Curious, why do you want a wider tire? I would try a Conti Trail King 2.4, those are "big" 2.4's. I currently run a Nobby Nic, and they are not as durable as Maxxis. I would ditch the Ardent and try the Conti or a Minion/High Roller II combo (Minion rear, HR II Front), those are some meaty tires. I would limit how big a tire your running because 29'er wheels are heavy enough. If you really want to go beyond 2.4, I'd get wider rims, but not wider than 30mm, which seems to be the point of diminishing returns:

I'd disagree with Conti tires...maybe on paper they look good but the three I have run and many others i see completely blow apart. I hade teo sidewalls and an entire tread blow out...junky.

Point well made. The issue I am experiencing is front end plow. My prior front tire was a cheap Conti wire tire and stuck like glue only problem is I could not use it when I converted to tubeless due to the weak sidewalls. I ride mostly rocky technical terrain and figure it would help traction in the turns (I also ride snow) if I go to a 2.6 as I do not care about weight . The ardent is marketed as a do all tire and got rave reviews. I should have known better as nothing does it all. As a rear tire it is fine as it spins easy and tracks good enough. Great tire just does not work for me. I was thinking of the tire choices you proposed as they are on my list.

Wow, I actually love the ardent 2.4s. I race with the ardent race or crossroads 2 . I use the 2.4s for rocky or loose terrain races like tomorrow at erie 80. I weigh 210 or so now and find the ardent has superior grip. I love it everywhere from hartshorne to cr to jungle. I use the exo tr version and run about 16-20 psi depending on conditions. I think it is an excellent tire if running rigid and the set I have now has been through many hell rides at cr with one tiny sidewall puncture while hammering down yellow rigid. Carbon wheels help keep everything stiff too.

I know, so many people swear by the Ardents, I was on the fence about even mentioning the issue. Everyone that has tried my bike has experienced the same front end plow. Other things come into play, maybe my seat is set up too high or the stem too short. However when I had the cheapo wire Conti's there were no traction issues. I'm not a racer and certainly no expert, I just love to ride. I never heard of someone running 29er tires at 16 pounds (still learning about this stuff) I think I will at least drop it down to 18 pounds for my Ringwood ride tomorrow and see how it works. Thanks.

I run bontrager rhythm pros 22.5 inner width. At hartshorne(fast hard pack) I run 20ish psi. At places like cr I run 18-19 and jungle I will run 16(low speed tech stuff where traction helps). I tried 16 at hartshorne and got rollover on the fast descents. Fat bikes teach you alot about pressure.

Those drop offs at Hartshorne are a blast. Good luck at the race tomorrow.
 
Your running 2.5's, so I suspect it's not your tires causing the plow. You mentioned your seat and stem before. Bikes with the "newer school" geometry require a different cornering technique, you really need to weight the front wheel before entering a corner. Sounds and feels counter intuitive at first, but once you get it you'll see. Try pumping into a turn, unweight before the turn and time it so you pump through. Took me the better part of a riding season to get it right. Also, a dropper helps immensely, getting that seat out of the way helps you get lower "into" the bike, and your arms into the attack.

While the cheaper Contis are junk, the higher end models with the protection sidewall are definitely not junk. Not as good as the Maxxis though IMO.
