Best reasonably priced wheels that are true

It's not the tires. I had the same problem with my old set that still had 8/32nds left. I went new BFG Radial TA again because my line locks wouldn't release a few weeks ago and I pushed my car across an intersection with the front wheels locked. It didn't exactly flat spot the tires, but there were definite rough spots. These tires are balancing the same way. When I take off my rear wheels and put on the ET Streets and their wheels, it is so much smoother. I can balance the wheels, but that won't make them any less out of round.

I have never heard of that brand of wheel, ProStocker273. Are they good, and more importantly, strong? Also, I have rear disc brakes and the offset and backspace are very important. There is no backspace info.
