My blazer feels a bit shakey after 70 MPH not sure what the problom can be but, I know it is not a alignment issue. One thing i did notice is that my tires are a bit eaten on the inside and the outside of the tire due to low PSI. I think my problom is tires but then again could it be that the tires need to get balanced. It only does this above 70 MPH. Car does not pull to the left or right. I took it to some alignment shop. They stated that alignment was good. What is your opinion. THNX

 

Mine does the same thing, it feels like a balancing issue to me. it really doesnt bother me becuase i dont drive that fast unless im in a hurry, i do 90km at the most on highways.

 

Could it be the tires that are causing this?? Im going to have to take my tires to get balanced at a small tire shop since wal-mart will deniy my car since my tires are worn out on the edges.

 

Rotate your tires and see if the problem continues.

 

Can also be the size of your tires. Bigger tires can make your vehicle shake at faster speeds.

 

Tires were rotated about a month ago, Ive had these tires for a year or so and never had this problom. Im going to risk doing the balancing. I kinda have a feeling it is that.
