This picture was posted on another site(s) by, which I'm sure, is a member here. I hope he don't mind me posting this picture. But, I just ran across this myself Friday. My '89 316 had weird off-set rims on the back that I could only get them mounted in the "wide" position. The offset was almost 90 to 95% to one side making it impossible to mount in the "narrow" position. A friend of mine gave me his standard rims and tires (23 x 10.50 x 12) and so I took both sets to the tire shop to switch over. When the free tires came off the rim, one tire had the green slime in it and the inside of the rim was a mess and starting to corrode. Bottom line, if you have a flat, get it fix or at least put in a tube. Don't use the green slime stuff.
