hey Al
most vibrations come from unbalanced tires, or miss balanced ..
First thing.. did you have the same shake before the new tires? exactly the same?
Is the shake still there above 70? 80? 90? get worse or the same?
What vehicle?
Have the wheels and tires been road force balanced?

Road Force balance is the latest tire/rim tech
it matches the high spot of the tire to the low of the rim to make the outer diameter of the tire as perfectly round as you can
Since no tire or rim can be made perfectly round, they all have high and low spots
example,,if new tires were installed, and the high spot of the tire was mounted on where the high spot of the rim, you will feel a shake from road force of the wheel and tire not being as round as it could be..kinda egg shaped
I would suggest road force balance.. if its shaking after that... it'* not the tires

if you purchase tire from a place that has road force, it'* usually included with purchase, some times the tires might be a bit higher, but add road force make up the difference and be cheaper in the long run
let us know how it goes.. and even have the shop show you what is going on.. they will be happy too

RoadForce is good for our cars, the tires have a low enough profile to benefit. Now on trucks that are used as trucks, crap.
If RoadForce doesn't fix it, check everything up front. Tie rods, sway bar links, swaybar and bushings, axels.
