Velocity Synergy rim / tire sizing
I recently had a wheel built, Deore XT 36h hub and a 700c Velocity Synergy OCD rim for touring. When I went to put the tire on the rim, Pasela Tourgard 700X35, it seemed to go on really loose and actually blew off the rim when I got it up to pressure. I know that tires and rims have sizing tolerances and possibly the tire bead diameter of the tire is at the "big" end of the tolerance and the rim might be at the "small" end of the tolerance but it's kinda unnerving as both are brand new. I did get the tire to seat but I really had to be extra careful. Any thoughts or ideas as to what the problem is?

I honestly don't know the answer to your question. That strikes me, however, as a pretty wide tire for a relatively narrow rim.

rim
Actually the wheel was touted as a touring wheel, the spoke hole drilling being off center to have less dish. The width doesnt seem too narrow. Even when installing the tire, it just slipped on with my hands, I hardly had to push at all. Weird.

I don't know if the size is an issue or not but I have noticed a lot of variations in how tightly tire beads fit rims. Some of the variations are in the tires, some are in the rims. I prefer tight fitting beads and would rather have to use levers than worry about a tire coming off a rim.

I have a Synergy OC on a Phil Wood hub that I use for training. I put a 700x28 Gatorskin on it and also noticed that it went on easily. It did seem like you have to make sure the bead hooks onto the rim when inflating it - but I have about 1200 miles on mine without problems. Not the lightest thing but it has stayed very true.

kind of late to the party, but the 700x28 gatorskins work great with synergy rims. however, schwalbe marathon plus 700x32 do not work. I ended up finding this:

and

apparently, i would need 700x37 in order to fit this rim, although I'm not sold on that idea.

I have Pasela TG 700X28 folding and I dont need tire levers to install or remove. When installing I put a few psi in the tire and check for trapped tube under the bead, and also check that it is seated evenly all around. Then pump to full psi.

i do this as well for all tires. however when using installing the Marathon Pluses, the tires are actually larger than the outside of the rim. i have to sort of push the tire onto the rim while inflating. it is very strange.
