    What size tire on stans grail ztr?

    I used to have a set of 650b wheels that used Stans arch EX rims. They were around 20 to 21 mm internal I believe. I successfully ran maxxis 2.2 ikons and 2.4 ardents on these wheels for a few years without any problems tubeless. Now on another bike I have a set of wheels using Stans grail ZTR rims in 700C which also has an internal diameter of 21mm. I’m confused why Stans says the maximum tire size for this rim is 40 mm when they said for the arch EX could handle over 2.2? The internal width between the two rims is the same or similar. Apples to Apples if you have two different rims of the same internal width by the same manufacturer, shouldn’t they both be able to take the same maximum tire size?

    The tire clearance thing has changed since they moved on to mk3. In fact, some 2.5” tires now have different profiles from that of the same tire a couple of years ago.

    Has anybody here ran 29er 2-2.2 mountain bike tires on these rims with good success?

    It's all relative. You can still run big tires on these rims, but don't run big tires with a lot of air pressure or you could blow them off the rim.

    That's too high for a 2.2 tire running tubeless on Stan's rims. I wouldn't do more than 35 and even that's pushing it.

    Does that always apply? I got Stans flow ztr rims on my other bike and typically run my 2.4 ardents around 30-35 but I have frequently ran 40-45 on gravel and had no problems what so ever. On these grail rims, I ran a set of 32s tubeless 2 years ago around 50-60 psi across Iowa on ragbrai.

    It does apply to all rims. I'm saying that Stan's does not recommend it and neither do I. Some tires can handle it and some blow off the rims. If you found a tire that works at that pressure than I would stick with it.

    So you’re saying that in general if your running tubeless with most tire rim combos you should stick below 35 psi? I get that now. But my main question was if I could run some smaller mtb tires on these rims...2.0 etc. sounds like they should work just fine and with that volume I shouldn’t need any more than 35. Plus I may run tubes. I am running tubes now with my 43 gravel Kings.
