5 /5 Kenneth: To Our Customers: Please take note that we are not a tire shop and that high speed vibrations you want us to check are most likely tires being out of balance. We test drive vehicles to the best of aur ability. If your car is vibrating at 85 mph we are not going to be able to help you. We appreciate all our customers but would like to be sure that you know that every issue you may experience with your vehicle is not able to be easily diagnosed. Please describe you concern you are having as accurately as possible. If your vehicle comes in for a noise, dont expect us to check your vehicle for a vibration. It may often not be related to the noise. Thank You. KEN
