Question: Vibration that increases with speed.

Had new tires replaced and vibration that increases with speed was very noticeable, almost intolerable. Took back to Tire dealership and asked them to check it out. They said that the rear right wheel was bent and that could cause it. I ordered a factory replacement wheel and decided to replace the right rear and right front with the spare to isolate the vibration. The car still vibrated no matter which wheel was replaced. Could it be a warped rotor?

Rotors will only cause a vibration when braking. Do you feel the vibration more on the right side, or did you try swapping out the left side too?

This is assuming there was no vibration before replacing the tires:
One thing that can cause a speed dependent vibration like that is a warped hub. How does a hub get warped? By over-torquing the lug nuts when replacing tires. The good news is the hub 'run-out' can be checked with a dial indicator--and the tire shop should eliminate this possibility. And lug nuts should be hand tightened with a torque wrench, not driven on with an impact wrench.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
