Strange wobble from ride side (passenger side)

I just leased a new 2014 tacoma prerunner v6 trd sport less than a month ago. This past weekend, I started noticing a strange wobble coming from the right-hand side of my truck (passenger side). It almost seems like my passenger-side front or rear tire is low on air pressure. But to my knowledge, everything looks totally fine.

At low speeds <10mph, I notice the wobbling the most. My truck wobbles side to side - again, it feels like one of my tires is low of air pressure: if I had to pick one tire, I would say it's the front passenger side tire. When I get to higher speeds, the wobble is less noticeable. I don't recall feeling this wobble prior to this weekend.

I do remember that this weekend when I was driving ont the highway, my front passenger-side tire ran over something on the road - it felt rather small, so I didn't think it would do any damage. Again, all my tires seem to look perfectly fine - no punctures, abnormalities, decrease in air pressure.

I'm probably going to take my truck into the dealer this weekend. But for the time being, any idea what may be causing this issue?

 

also couldve lost a wheel weight and tire is out of balance. Sounds a bit extreme for wheel weight issue though.
