Yah I read some of that, that ice and snow is freezing in the rim causing them to become unbalanced. I'd know how to fix that right away but the Mrs won't, so I don't want her to have to deal with something like that.
I'm worried with the 18s that maybe the car would feel like it would want to dip and roll a lot more in a fast turning situation? Maybe I'm overthinking it. 18" rims are still big rims compared to what we used to run years ago. Thanks.
