Excessive snow/ice build up

[myfirstyota]

So as the title states, I'm getting excessive snow and ice build up inside the rear rims. I don't ever remember having this problem on any other of my cars.

I'm running a stock 15" steel rim. The issue is the buildup isn't always balanced causing a bad vibrations at speed.

The vent holes in the rim don't really allow for easy clearing of the buildup, and as these tires were just mounted a month ago I don't really wanna spend more money on an open faced style rim (think 5 or 4 spoke) that would allow for easy clearing of the snow and ice.

Anyone have any tricks? Do i gotta coat these puppies in Pam (cooking spray) so nothing sticks? Lol

Any thoughts or ideas are welcome!
