So I bought take off camaro wheels and brand new nitto nt555s for my car about 3 months ago. Put them on have a horrible shimmy. Go through the motions at the time our shops roadforce was out of wack so I tried balancing and wheel torque and nothing changed. Finally got roadforce back up and tire had 28lbs of roadforce. I phase matched it brought tire down to 11lbs. Car drove good for a few days. Shimmy came back. Roadforced same tire had 27lbs of roadforce so I had my parts manager warranty me a defective tire. Put new tire on had 2 lbs of roadforce I was like sweet car drove great for a few weeks then shimmy returned. Roadforced tire again and it again had 27 lbs of roadforce. Phase matched the tire again and had like 8 lbs of roadforce. Now a few weeks later after car drove like new I'm starting to feel the shimmy coming back???? Has anyone had issues with certain brands of tires with replacement and had issues with maybe a bad batch or am I missing something here? Any insight would be awesome. The rims are straight and it's only the left front that I'm having issues with. All control arms, end links, inner and outer tie rods and strut mounts have all been replaced during this time.

Tire experts advice needed
Sounds like belts are shifting. The changing phase matching proves something is moving in the tire. The only things that can move are the belts.
Let's see, it's 2 tires, the original on the left front and it replacement. The original was road forced twice then replaced. Now the replacement has gone through 2 RFs also. Looks like you got 2 bad tires but 2 in a row seems just unlucky and doesn't say much about Nitto quality.
You point out suspension part change outs but the problem is 100% isolated to the tire by the roadforce equipment. I know, you are trying to rule out variables and bad parts/alignment killing the tire. But bad alignments wear out tires over many miles not cause belts to shift.

Yeah 2 tires seems unlikely but I feel it coming back. Didn't think about the tire paste possibly causing the wheel to shift. No weights have fallen of that I'm aware of. Everyone I work with that has trucks swear by the nittos and it seems I'm the only one with issues. Maybe I'll try another brand down the road. Just not sure why the tires roadforce would keep changing like that on 2 separate tires.
