Wide Tires on Narrow Rims

Anyone running wide tires with narrow rims ? Any problems ?

I just got a set of 26 x 2.25 tires and want to put them on a mavic xc 717 rims, 17mm wide and in the specs for the rims it say recommended tire width 1.0 to 2.1 tire size

I was running a set of tires 2.0 no problems

I know I need a wider rim, but no funds to buy a new wheelset

So, can I just lower the pressure on the tires? Is there any possibility of these tires blowing off the rims? or any other problems?

thanks

Use similar rims (X317, X517s) with various tires from 2.25 to 2.4 (various WTBs, Schwalbe Fat Alberts) with no problem, can't run 'em too low without getting a tad squirrely in hard turns, though I run 25-33 range usually. I also use wider rims (321s) for a bit more stability for some 2.5s...

i'm not advocating it, but I somtimes run a 2.5 on an xc rim (one day i'll have the right rim) and on my cx bike that i just converted to flatbars and put the panaracer cross tires on which are a 45c, and measure out to a 29x 1.9 mounted on open pro rims... prolly not advisable, but i've had no problems

I wouldn't sweat a 2.2 maybe stear clear of a 2.35 or a 2.5

Run the Schwalbes around 30 myself. It's at 25 (or below if I'm lazy before a ride) that I can feel much difference...
