how to remove hub rings?
 

yep, went to put the winter shoes on the car and can't get the hub rings off. anyone got any hints for this? tried tapping it with a hammer and flat head screw driver to losen it up but that didnt help any, was going to spray it with some wd40 but the roommate used it all so still got that to try.

Spray a tiny bit of pb blaster on it, JUST MAKE SURE NOT TO GET ANY ON YOUR BRAKES/ROTORS!!!
