I'd like to quiet my 07 RX440h down a bit. What should I do to reduce road noise?
Tks for your ideas.

 

New tires is about all you can do. Check the tire noise survey results on Tirerack.com. The Yokohama Parada Spec-X tires I bought from them are pretty quiet.

 

The newer RX450h has thicker glass and more sound insulation than the previous generation RX400h making it quieter. Short of tires as everyone else has suggested, there are few options other than purchasing some Dynamat or similar to cut down on some of the noise.

 

I found some sound deadner on fleebay for $25 and am going to install in the Rear decking under the floor area. Manly have said it make your ride quieter... Will see.

 

can you take some pictures along the way also? I am down to make the change if the cost is under $50..

 

yes i will. might be a week or so, my kids are in town, no time right now.
