3, yes, 3 F**KING BENT RIMS!

well, just got my winters off and got new Kumho Ecsta ASX put on my rims...at which time the guy tells me three of them are bent! WTF!!!!!!!!!!!????????

That would solve my vibration over 100km/h I guess. But now what!? I can't afford 4 new rims! UGH
 
That sucks man, but the answers are obvious. You need to either buy new rims, buy used rims, pull the studs out of your winters and run them, or put up with the vibrations caused by your bent wheels. Can the wheels be straightened?

If it were me and I had zero money, I would pull the studs and run the winter tires until I saved up enough for new wheels. Unless you have another car to drive during that time.
 
Some shops will have generic steelies for as low as ~40 dollars US. I got my 15" for about $30 a piece, so I'm just guessing for the 16" rims.
