A Z is going to produce more road noise then a regular car but the tires have much to do with it.
As a rule I think you can always expect to feel every road imperfection and hear alot of noise..more so then say a sedan.
If you remove the upper carpet in your truck you will notice a plastic type piece that goes over your spare. I put sound insulation there and it removed alot of that noise.
