Hi,
My 97 VW Passat was driving smoothly UNTIL I had two new front tires installed.
I moved the old front tires to the back and got rid of the back tires.
The old front tires which have been moved to the back are a DIFFERENT brand than the new front tires and will have less tread since I have been using them for about 6 months already.
All the tires were balanced by my mechanic when installed. However I did NOT get an alignment done as I had one done 6 months ago.
Now my steering wheel vibrates when I drive faster than 60-70mph.
Can anyone tell me why this is happening and how I can correct it? Please email me if I have missed some relevant information.
Thanks, Anwar
