2015 tundra vibration/grinding in gas pedal

2015 tundra SR5, haven’t changed anything since I bought it and drove fine till 2 months ago I feel a vibration/ grinding feeling in gas pedal, when I’m slowing down and let off the gas pedal a little while slowing down I feel it. TIA!!

 

1.) do you get steering wheel shake?
2.) do you also feel it while braking?
3.) when you get on it then let of the gas quick is there a clunk or pop

so far I'm leaning towards the carrier bearing for the two piece drive shaft to check first. but a lil more info could steer it to a different direction.

 

No steering wheel shake and not while breaking, and there’s no clunk or pop at all I do have MT tires on it which is my first guess at the vibration but I will check the carrier bearing

 

MT tires will vibrate, some more, some less depending on RPM. If they are a new addition, that may be it.
