A good rule of thumb for tire width WRT to INSIDE Rim Width, IRW:
ROAD:
1.4 to 2/2.5 times IRW so for a rim with inside width of 17mm: Tires
of 24mm - 35/42mm or so. Brake and QR release will temper max tire
width choice for easy tire removal.
MTB
1.4-3 times IRW
The IRW of most rims will be about 4-5mm the outside width.
The width data above is consistent with recommendations given from
various sources: Peter White, Sheldon Brown, Mavic, Barnett's Manual,
and others no doubt. Look-up and validation is left as an exercise to
the reader.
So for the Hetre. IRW of Synergy rim = 17mm.
40mm/17mm = 2.35, within the range mentioned above.
I have Synergy rims and can say Hetres work fine with them.

What rim width does a red balloon, err, Hetre need? Will the Velocity
Synergy 650B wheel handle it?

After riding Fatty Rumpkins and Hetres, 40+ mm, I just can't see me
riding a tire as skinny as 33m any longer. At least not on my 650B
bikes. Once you go fat, you won't go back! :-)
