Do ET Streets (bias-ply) cause vibration at higher speeds?

The guy in the red Maserati that was shadowing me all the way back through Plano would have certainly had his feelings hurt considering my gf and 5-year-old in his car seat were onboard! LMAO!

The et streetS I was running vibrated at 80mph at the track. Never drove them on the street.

Bias tires move with heat, they also flat spot when they sit, the flat spot will work its way out as the tire heats up from driving, I could easily see some vibration at highway speed especially if they aren't balanced

these are static balanced on brand new welds, but since they are not screwed in i have no idea if the tire has spun on the rim. the flat spot theory seems very plausible though because sometimes the vibration seems worse than other times.

i went ahead and bought 2 "heavy duty" precision 1310 u-joints as I am on unknown stockers right now and i think they are pretty worn (clunks into gear and light throttle shifts).
