Paul :
This may sound strange, but it worked for me :
Try having all 4 wheels "bubble balanced", using a balancer that engages
the lug nut holes, instead of the center hole. I had a similar problem on
my motorhome some years ago (sometimes the steering wheel would shake so
hard it was difficult to hang on to), and that fixed it.
According to the mechanic who suggested it, most balancers grab the center
hole, which may not be concentric with the lug holes. He also claims that
bubble balancers are more accurate. (Not sure I believe that, but he DID
fix my problem.)
We also tried this on a 56 TR3 with a small vibration at 65, and it seemed
to help.
You don't say if you tried having the new tires spun on the car (need to do
all 4, which most balancers can't handle), but I would think that would be
equivalent to using the off-car, lug hole balancer.
