Cabin noise with Mud Terrain tires

I have a 2020 TRD with 3” lift and Cooper STT Pro’s (Louder than expected) I’m going to do a speaker upgrade and tear out the cabin and do some sound deadening in the process.

Question: Where do you think the majority of the tire noise comes from inside the cabin? I may do a little extra in certain spots if it will help with M/T tire noise.

 

There’s very little material behind the back seats. It’s a good starting point to start with the deadening.

Those tires are awesome but you’re right they are a bear to deal with every day.

 

Doors are the noisiest part of my truck. Probably the rear wall after that. Then again I don't use noisy tires, so YMMV. Most of the tire noise will probably be in the kicks.

Seeing how you're going to do a speaker upgrade though, you might as well knock out the doors first since you'll be in there anyway. You don't have to rip out the whole interior for those and can do them one at a time. And they're the most time consuming if you're doing it right (damper, barrier, decoupler, and maybe absorbers).

 

I've done my doors and floor so far, which have made a big improvement. Now it seems most of the noise is coming from the back wall, which will be addressed in the spring when I replace my sub box.
