Quieting road noise?

[aquamans350]

When I first bought my truck I thought it was really quiet. however, I find as my tires are wearing down, road noise is increasing to the point it's fatiguing on long trips.

I don't want to go to the extreme and dynamat the entire cabin.

I have a long-wheel base, so I'd 'think' most of the noise is therefore coming from the front tires.

I saw the door seal mod, but it's not clear it reduced road noise based on some earlier posts.

Does the back cab wall transmit much noise?

Any of you have suggestions where the biggest bang for the buck would be to seal out / dampen road noise?

I too have a LWB truck and find the noise on quiet mornings a real nuisance

I'm hoping to dynomat in the next few months the entire interior, including floors and also going to do the underhood. Hoping to quiet her down a bit.

Any idea what that costs?

I'm thinking around $1000-$1200. Dynamat is not cheap!

Is that just for the Dynamat (with you doing the install) or is that a complete price including install?

My pickup is a 6 speed. I took off the shift boot and put extra foam between the trans and body. Made a huge difference.

Figure on needing around 144 square feet of dynamat extreme. You can find it on-line in a megapack for $285 for 72 square plus shipping. I figured on a total of $600 more or less. From what I've read it would take about 6-8 hours to do the entire interior and I figure on any shop charging $50/hr. I say take the 8 hours at $50/hr and you have $400 for a grand total of $1000. I'm hoping that is fairly accurate.

If y'all had only 30sqft of dynamat to work with, where would you put it? Is the floor the noisiest contributor?

The doors seem to be pretty quiet, but I notice I can hear raindrops strike something near the B pillars at freeway speeds. They seem hollow. Not sure if noise is coming up through those...

The air vents on the rear wall of my F150 let in tons of noise. The F350 seems to baffle it a bit with the insulation overlapping the vents.

could try dynamat or fatmat on the backwall first, I notice when my back seats are folded down, I hear alot more road noise.
