Check out this thread:I want to know where that extra sound deadening material is missing from my LX so I can add it back. There's a lot of road noise on the older, less well maintained highways......
I just upgraded the OEM tires with Michelin Premier A/S from Costco -- They are doing a deal right now for $130 off a set of four tires if you use their Visa card. https://www.costco.com/auto-tires.htmlSomeone mentioned that there is more sound deadening material used in the touring model. I have a touring and find that it's very quiet on the highway. On concrete surfaces it's a little louder but I suppose the cheapo tires (Firestone) can be blamed.
