Choosing Tire Size

I have a 2007 Ava LTZ. It came with 20" wheel and 275x55R20 Bridgestone H/L Alenza. I want my truck to be the quietest inside the cabin. I am coating the wheel wells with sound proofing undercoating paint. I need suggestions on the tires.
I would like a taller tire like 275x65R20 which bring the truck up to 34" from original 31.9", away from the pavement. Anybody out there have any suggestions, tire size? Under coating? tire height? tire make?
What make/brand is the quietest ride out there?
 
There is a mountan of threads dealing with tire sizing and you can find info reading them. I always replace my factory tires with Michelin tires for qiet ride, good traction and long life.
If you really want to quiet things down as far as road noise you should get a Dynamat hood liner.
You also have to remember to get your odometer and speedometer calibrated if you deviate from stock diameter.

This sounds great but I am looking to quiet road/wheel noise.
 
lots of noise is from tread and road construction.

You would be surprised about how quiet it will make the cab of your AV since not only motor noise but road/tire noise is amplified inside the engine compartment by the hood and thin factory hoodliner. Once I installed my Dynamat hoodliner It was very quiet and to hear my CAI and Corsa Sport exhaust I have to roll down a window to hear them in their glory...:devilish:
 
Anytime you can make it quieter inside, you benefit in better sound quality from your stereo. You don't have to turn it up as loud to drown out the outside road noise.

The first thing I did to reduce outside noise was to put these on the floor, pulled the seats and carpet, sorry I forgot to take pictures. It made a big difference.

Thermo-Tec 14720, 36 in. x 60 in. , 2 needed, one for front, one for rear.
Dynamat 11102 0.250 in. Thick, 54 in. x 32 in., 2 needed, one for front, one for rear.


Second thing and the biggest reduction I found was when I did the doors. I put a strip on the top and one on the bottom of the outside door panel. And the completely covered the inside of the door where the clear plastic rain shield goes. This reduced the noise that comes in through the opening or drain in the bottom of the door. Again, to me this was biggest reduction in outside noise.


Dynamat Xtreme, .067 in. Thick, L 18 in. x W 32 in., 8 needed, 2 per door.



Edit: I should also mention that adding the insulation for sound deadening also has a benefit for making the passenger compartment more comfortable in hot/cold weather since your cooling/heating system will have an easier time conditioning the space...

Thank you for your extreme detailed help.
 
I finally did it. I am in the test mode so I replaced the 275.55r20 with Bridgestone Duelers 275.65r20 and the tires touch when turning, so, I then went and put Bridgestone Duelers 275.60r20 and they only touch when turning really fast and hard on a u-turn. I went ahead and bought 4 used 275.60r20 for $200 and I will test for a while. They have 1/2 of the thread so they should last half of the 50,000 miles. The truck went up in height by one inch. I am happy.
