This is a silly expensive trick, but it works. When I sell Geax TNT tires, I set them up on some crossmax 29er wheels overnight. This stretches the bead dia slightly and allows for a much easier time mounting the tire. We sell tons of the Geax TNT 29er tires in our shop, specifically on (current) Stan's arch and Flow rims. These tires offer a reinforced sidewall that is very durable. I personally just finished the San Juan Hut to Hut trip from Durango to Moab on this exact setup. I had zero issues. (even on the porcupine rim trail which is notoriously tough on tires). I have now worn out 4 of these tires w/o a single burp or casing tear. Much of this riding was done with loaded panniers offroad. If the inner bead seat dia was to get any tighter, these tire would be impractical for most people to mount. With the current tires and rims, it is tight but not impossible. You will dent a rim way before you burp a tire. Personally, I would go for a tight fitting tire any day over a loose fitting one. We sold every sagauro tnt tire I could get this season from our suppliers. When they ran out, I switched to the WTB Wolverine. These mount much easier, are way lighter and roll nearly as fast. They also offer better cornering. The thinner sidewalls are worth noting though When WTB brings TCS to market they will simply dominate in the 29er tubless world .. IMO. Tires are really a test of good old trial and error. At this point there are huge variance in bead diameter form one mfger to another. (and even in the same brand, Sometimes in the same tire) These are my personal findings on tire seating using the Current Arch 29 or Flow 29 Mounted with Stan's Yellow tape. All in 29 of course. This is just what I have found. Your results may vary wildly. All in folding versions btw: Geax TNT- Super tight wtih Burly sidewalls (toughest and heaviest going) Geax- Tight WTB- Tight enough and ok sidewall toughness Hutchinson- Tight Kenda -Loose to Scary loose Michelin- Loose with tear-prone sidewalls Maxxis- Loose to acceptable Maxxis EXO - Tight enough and nice sidewall toughness Conti- Loose to acceptable Schwalbe Tubless ready- Tight enough Schwalbe - Loose to scary loose and mega thin sidewalls J- Geax TNT’s mount tight, but not so tight to ignore how well they ride.

So far, Geax and some Bontrager tires seem to be quite difficult to mount on a Stan's rim. Now Stan's has introduced a newer BST design with the Crest, and all indications are that these tires I listed are so tight that they are impractical to be considered together. Furthermore; Stan's plans on introducing the newer BST with its slightly increased bead seat diameter throughout its line up, making Stan's entire line nearly, or completely incompatible with UST bead spec tires. It would be best to avoid these combinations, in my opinion, and stick to the systems emerging, (WTB's), or that are already in place for UST bead spec tires like Specialized's 2Bliss/Roval wheels, Bontrager's excellent TLR system, or the like. Finally, Geax tires tend to be a really tight fit, and I have had troubles getting them on other rims as well. Although Hutchinson and Bontrager TLR rims tend to play very well together. Stans works better with Conti, Panaracer, and other non-UST, non-tubeless ready folding bead tires. Although, care must be taken, since folding bead tires are not tubeless rated, so doing a non-tubeless tire on a Stan's rim assumes you take the risk. ;) @DanH: Geax, Bontrager, Specialized, and the upcoming WTB TCS tires are all based off UST specs for the bead shape and diameter.

Should I be worried using them?

Does anybody know of a shop that has these in stock? I can't seem to find them anywhere. I would really like to get a set of these in the TNT version.

This is my 1st 29er tubeless setup. I ran the Stan's Flow rims and latex sealant with great result. i ran about 25 psi on both and at 210 lbs I hit the rear rim just once in 3 hours of riding. I know I would have pinched a tube on such a hit. They seem to roll as fast as the Hutchinson Python but at the same time they offer much more traction. These will be staying on the bike for some time. Love em! j I really loved this tire on my first ride with them the other night. This is my 1st 29er tubeless setup.
