Of course interior noise is affected by the cars suspension, noise isolation, and noise insulation as well as the tires. The only thing I can control is the tires and I can't very well conduct my own tire survey. The only published data I have seen is the Tire Rack user survey where it scored good for noise and comfort. In addition, I have read many professional evaluations and don't recall negative comments on tire/road noise. However, some of these tests were conducted with the 215/55R17 Hankook 426 tire (note that a 55 is naturally quieter than a 45). My question: have any of you experienced "excessive" road noise with a 2012 Passat? and if so, or if not, what tire is on your car? I realize that noise is a judgement and for years I have been driving an Audi A6 which has a relatively quiet ride.
I didn't know h-o-w noisey the Hankook P235/45-18s were, until I changed-out my fronts (due to sidewall damage) to a pair of Michellin Pilot MXM4. Then, after reading more data on tirerack.com, I decided to change-out the rear tires to the Michellin Primacy MXM4s from Costco. Even that the Hankooks were still very new (only 10 weeks), my point of view was to really enjoy my Passat TDI SEL to the fullest. The extra $1,000 in Michellins is a lot, but so is buying the high-end TDI. So now I have an even more enjoyable car, -that rides even smoother and quieter, plus the added confidence that I have in the Michellin Man. Lastly, I think that Bridgestone makes some very good tires. As a "eco-greenie", -if they had the Ecopia 422s available then in my tire size today, I may have easily chosen them as a replacement vs. the Michellins. In my situation, I hit a huge pothole while on vacation in NM. At the time (Mar 2012) the two ABQ Costcos didn't have my size available, and Discount Tires (aka Americas Tire Co) only had the Michellin Pilot, or else some way-lesser tire. Road surfaces and conditions mean a lot, but this was my solution to hearing my turbo vs the tires. It's always a personal choice.
