Dammit I've got a wobble

well its been snowing like a bastard here so the roads are all covered. The roommate and I went out in the truck today and man i missed the snow. anyway driving down the highway I noticed I had a wobble checked the wheels no ice build up ran my hand along the sidewall and there are two small lines that run perpendicular to the profile they're definitely indented but not very friggin much. So you guys think they're just out of balance or is there a bigger problem? I haven't been driving very fast or far so I don't really think they have had a chance to warm up so could they just be frozen out of round?

 

its very possible that they flat spotted while they sat overnight. i dont really think you have anything to worry about especially if it just started to happen.

 

thanks dude needed a second opinion. I'll take it for a good drive tomorrow and see if it goes away.
