Bias ply tires up front w/ radials out back is not your problem. I've been 156+ mph w/ a stock suspension 3800 lb car w/ 295-65 radials (15x8 wheels) on the rear and bias ply M/T Sportsmans up front. The car drove perfectly fine.
not the same, trust me. He has a 14 inch wide tire, which i believe is part of the issue . i went 8.78 at 153 mph and almost lost it due to "radial rock" like the author discribes. 3000 lb Dart. The car ocilates side to side violently. And when guys watching your 8.78 run ask why you didn't lift, it is very serious!
