Vibration on right front tire at 70 mph to 75 mph

put tires from rear up front and front to rear and see if tires cause a shake also make sure no debris on hub so rim sits flush if no change and still vibration check drive shaft and u joints

When you put the vehicle in drive with your foot on the brake, and you hear a clunk. You may have a bad CV joint or axle. If not it may be a bad wheel bearing. Those would be the first two I'd Check. Outside of that sometimes poor wheel balancing or a tire belt separation. Either way it should be looked at before you hit 75+ mph. I had a Honda that I had just got off the highway with my wife and 3 month old daughter in the car. On a side street pulling away from a stop sign. The right CV shaft let go and dropped the wheel on the ground. There wasn't as much as a shimmy or a groan prior to that. If we had stayed on the highway another five minutes, I can only imagine. Please check it out for your own safety.

Its possible you have a damaged wheel. A wheel could have been damaged/warped when the first set of tires were replaced. Spin balancing machines "balance" the tires at about 30 mph. Generally that covers things up to 60 or 70 mph on the road.
You may need to have the wheels checked with a gauge to see if any are warped or bent.
Make sure the vibration is not affected by engine torque or other factors. Does it matter if you are coasting at 70 mph or pulling, etc.
A miss-fire in the engine could be transported thru the passenger compartment and cause the same effect, but the check engine light should come on.
If the problem started right after the new tires, I would look at the wheels first.

Warped or out-of balance brake rotor? Also keep in mind that loose rear differential trailing arms that allow the rear differential to squirm around can also cause steering wheel shake.

I'd have to check your suspension. You think the tires are ok? Did you try rotating the tires to see if it made any difference?

I'd guess you have a tire out of balance, it sets up a harmonic around 30 to 35 mph, and at twice that speed, or 70 mph. I suspect if you drove it at 120 to 140 mph, you'd find another one. Could also be a tire that has a belt that has failed.

How many miles on this set of tires, did you get a lifetime road balance on them? Hazard warranty? How soon before you need new tires. Need to take all of these into account, but need to correct the problem before you have a tire failure and a wreck.

Most likely with this problem is the front tires. The tires maybe " out of balance " or " out of round " causing the vibration at certain speeds.

I had a similar problem. The dealer change automatic transmission and differential, but the noise continu. After research on internet i think the problem is the front galiper who create a vibration on the disc wheel and the vibration frequence follow the front axle until interior car. Just press slowly the brake pedal and if the noise stop , that's it the cause i think. I dont change my galiper, but i have a new transmission . :)))

Must be bad u-joint. To check it, let off the gas pedal. If it stops right away, it's the u-joint. If it takes a few seconds, it's a tire out of balance, or a bent wheel.

Lift the back of your car.With a stable rest and with the two hind wheels hanging, run your car up to the speed where you experienced vibration. have someone take care of the throttle and shifting while you observe the transmission shaft. You may have an imbalanced shaft.
