No issues in regards to the drive and vibration? I want to go with the Pirelli tires again. So it’s just cosmetic you think?
No, I think they ride and handle OK, although I have a few times noticed a vibration, but it seemed to be on the same stretch of road, so I think it is just the pavement. Mine also have other cosmetic imperfections, there are places on the sidewall where there is a brownish streak that can't be scrubbed away, it's like the rubber is a different color there. I am curious to see how the treadwear goes on these though.
That was my big complaint with the Bridgestones that came on the Tahoe when it was new. I only got about 25k miles out of them. I replaced those with a higher model of Bridgestone (Alenza's), and then had to have them replaced under the mileage warranty at about 27k. The replacements only lasted about 25k as well, so I switched to Michelin. I get about 60k with them, and I think they ride better.
