So today I attempted to rotate my tires because the front tread is wearing out. I took off the lug nuts from the rear right wheel but the rim did not come off. I thought maybe the tire didn't have enough clearance off the floor so I checked it and there were more than 2 inches off the floor. I tried to keep pulling the rim out but it would not move at all. I took a rubber mallet and banged on the inner side of the tire a good bit but that did nothing. I was stumped so I decided to do it another day since it was getting dark. I'm thinking now that my rim is rusted or seized onto the hub? I've had the car for 3 months and this is my first attempt at removing a wheel from the teg. It came from Illinois and Michigan where it snowed a lot and there is a significant amount of rust on the undercarriage. I sprayed some penetrating spray onto the hub but nothing helped. If anyone has any ideas on how I can remove the rim, please do so because I need more traction in the front soon. Thanks.
