Monday after leaving work my car was starting to wobble a bit about 30~35mph. Got up to 45~50, and anything faster than that probably would have given me an earthquake experience; you could see my steering wheel vibrating at the 45~50mph mark.
I didn’t really have a safe place to pull over(plus it was like 15 degrees and real windy outside), so I kept my speed down til I got to a place I could pull into to get a look. The steering wheel vibration made me think it was the front tires, but the lack of my TPMS lighting up made me wonder what was really going on. The vibration felt like it was coming from my driver’s side wheel, so that was the wheel I paid more attention to when I got a chance to look at it. I kicked what little snow had accumulated in my wheel wells off, in case that might have been it, but it wasn’t.
I had my battery replaced sunday, so I thought that maybe the TPMS might not have been fully “settled in” to read correctly, so I checked the pressure, which was fine. I should have checked my passenger tire when I checked my driver’s side, but I was in a big hurry to get home.
This morning I went to check the pressure in my passenger side front tire and found the REAL culprit to my vibration; snow had accumulated in my rim and froze in there. I couldn’t even get to the valve stem because of snow/ice accumulation on the rim. Chunking off what I could this morning before I left with my ice scraper made some of the vibration go away. Checking before I left work today I was able to clear off most of the snow/ice out of there before I left.
So, in conclusion, while I am OCD about keeping snow/ice off my wheel wells, I have never thought to check the rims because I have never encountered this problem before in all my time driving. Not only should you check your wheel wells for snow and ice, you should check your wheels as well.
