Hood and fender shake

Alright, I have found the problem. It IS the back tire or tires. I borrowed a couple of ralleye wheels from my friends Dart and bolted them on and went for a ride. The shake was gone. He had 235/60/14 BFG Radial T/A,s and I was hesitant to try it but the shake is completely gone. Even his worn BFG's were better than my new ones. Sounds to me like the re-pops are losing some quality control. Anyways, I have the cure, now just to get 2 more new tires. Thanks to all for all your suggestions, it has been fun!
