Car pulling to right under acceleration

Alright guys, I've tried just about everything at this point:

• Tire pressure same all around.
• Moved rear wheel with new tire to opposite side (driver's side), and now pulling to the left instead of the right.
• Went back to Costco thinking it was a defective tire, and got another new tire. Nothing changed, pull is still there and the same.
• Figured it may be a bent wheel. Went to a wheel shop, and both rear wheels are true.
• Went and got an alignment, and I'm in spec.

After all of this, the only thing I can think of, is that the SLIGHT tread difference is actually causing this drastic of a pull under any acceleration. But I still can't wrap my head around the fact that a 32nd of tread difference is causing me to basically drive crooked during accleration, and the second I take my foot off the gas, the rear of the car kicks back the opposite direction and steers straight. But maybe that actually is causing uneven grip when any power is going down?

Has anyone encountered anything like this? Maybe shave the new tire down? If it's actually a new tire issue, maybe it will fix itself as the tire settles? Or am I at a point that the best decision is to just get another new rear tire on the opposite side?

I'm willing to do about anything now, because the car at this point is pretty close to not being reasonably drivable.

You haven't tried the BMR lockout kit

I don’t understand...I wasn’t having this issue at all before my flat tire. How would this make a difference?

Since you switched the sides of the tires and the pull followed the tire, then it's pretty much a guarantee that it's the tire that's the issue. Are you sure the old tire is within 32th of an inch of the new one?

It probably wouldn't, hence the LOL.

You'll probably need to replace both tires to get rid of the issue...if the car wasn't a GTPP, I'd suggest just doing a front/rear rotation, which isn't possible in your setup, since it's not a square setup, unfortunately...

I misread your comment. My bad lol!

I was trying to avoid that...you don’t think the issue will settle itself over time?

Honestly go try doing a burnout for a few seconds to get the new tire's surface scuffed and worn down a bit. You can add water to the old tire side to reduce the friction to preserve more of the tread. Add chlorine water to the new side to increase the temp if you'd like.
