Plugging Tire???

Ok Guys,

I got a nail in my tire yesterday. So my friend plugged it for me. Now the same tire is causing very bad VIBRATION!!! I have never pluged a tire that is streched. Has this happened to anyone before? I'm going to get it balanced. But never have had to balance a tire after plugging it from a nail. I didn't drive on the tire when it was flat. Saw it was flat when I got up to go to work. Filled it with air and went right over to my boys house who plugged it for me. So I don't think I bent the rim or f*cked up the tire. 

what do you guys think?

It might have bubbles so check the side walls inner and outter if you haven't checked it yet

If you're unsure, take it to a tire shop to double check. Better safe than sorry.

not everyone knows how to work on stretched tires especially if they are trying t flip the tires.  like the guy above said sounds like bubbles in the tires

bubbles or either when the plugged it they didn't cut off the excess thats being exposed on the outside? not sure if that will cause it to be.... but something to look at.

and did he plug it with it being on the wheel? did not remove it right? is that even possible lol
