Michelin Pilot AS4’s installed and I would say on my 100km drive home, they were definitely quieter and I would say smoother. Unfortunately, dealer was not able to perform the alignment I was hoping for, and he thought he could do
he had new equipment but not the extra attachments required to set up a camber closer to zero. Interesting to mention that the alignment on the original tires was within GM spec when it was on the alignment rack, but tire wear was severe on all four tires on the inside edge at 26,000 kms. I am not an aggressive driver, never on a track…Be Aware!
I will leave the alignment until spring as car goes to storage this week. If anyone knows of an alignment shop in south western Ontario, that has the proper equipment to do this, I would appreciate if you could let me know.
