I have always used dynamat for noise and sound. Sometimes strategically placed pieces can make a big difference without doing the whole interior. Like just one large square inside the door can be as effective as doing the whole inner skin. You can try pulling the rear seats and covering that area. Tops of the wheel wells helps a lot.

Reason: wrong word
I just had a high end stereo installed in my daily SUV and they put Dynomat all over the doors and rear end. It makes a huge difference - almost completely eliminates tire/road noise. My advice would be ask high end stereo shop where to install it and whats the best product.
Cool. I agree that road noise from the rear wheels is higher than I'd like. New PS4 tires helped a lot, but doing the fender liners seems like a much easier fix than pulling the interior panels. And if you ever need to return to stock, it's likely much easier to work on the fender liners (or just replace them) than to pull adhesive mats out of the inside of the car. Please post more feedback!
I swapped out the old dog meat tires and ride w the new Michelin Pilot Sport 4S compound. I don't track so these are great for street and they are a 100% improvement over the last Michelins and are actually quiet on the street. This however, looks like a fun project so next month I'm going to wrap the rear inner fenders just for fun.
Here is a good summary of Dynamat vs Hushmat vs Fatmat vs Peel and Seal. Seems Dynamat is the favorite according to this car stereo stie: https://stereochamp.com/fatmat-vs-dy...peel-and-seal/
I'll go with the Dynamat based on this write-up. Hushmat is a close second but seems the product won't serve well in high heat, like AZ.
Earlier this month I installed the Dynamat fender liner in all four fenders. The install was fun and not tough at all. Prior to doing the work and after the install, I took an array of sound level measurements at different RPM and speeds. Bottom line: epic fail. The exhaust system is too loud to accurately measure any decibel variances. Fine by me - I like loud pipes. However, there is a noticeable audible difference. In plain English, the best way I can describe it is to say that the "cabin noise" was more muffled after the fender liner installation. The difference is akin to listening to great audio in a room lacking in acoustical absorption versus one with proper acoustics. Sound absorption increased after the install and there was less "bounce". Not a great description, sorry. No question IMHO the project is worth the minor expense.

Did you notice any significant decrease in road noise? That’s what I’m after.
