c. Jack each wheel up one at a time just to point where you can turn it freely by hand, but no further.
d. Take any very squared off block of wood (2 x 2 of 4 x 4 etc) with a length that runs at least across the entire tread or more & keep firmly placed on the floor just about 1/8 inch in front of the tire. SLOWLY turn the wheel by hand & see if it the 1/8 inch equal distance around the entire tread holds.
Since you mentioned you can feel it rather than hear it, this will rule out a defective tire. I had my tires react this way when I would rotate them. Some belts didn't like to reverse direction, but I know your case doesn't involve having rotated your tires.
Hope this helps.
I'm a bit of a machinist, so when i've got this on a lift, my practiced eye will be able to see <.010". And across the tread too. I'll especially keep an eye on the rims. since they are aftermarket too.
Thanks though!
As an afterthought, since these are one-direction tires, I might just mount them up "backwards" and take it for a spin. Might be interesting?
