sound insulation for highway

Sun Feb 26, 2017 10:15 pm

hey guys,

I am quite happy with the new (to me) leaf, but I expected it to be a bit quieter on the highway. My main complaint is noise from the tires probably, as I cannot hear wind noise like I can hear in my other cars. Has anyone done any testing to add insulation (like dynamat) to reduce interior noise at freeway speeds?

changing out tires with good tread is not a good economical choice either, rocking the stock Michelin energy saver a/s right now on 17s.

cheers

Tires do seem to be the main variable when it comes to road noise. I'm not sure it makes sense to try to insulate the whole car from tire noise. Try experimenting with different tire pressures.

My buddy has a car audio shop and he uses dynamat for sound deadening. Fatmat is another good material
