New Yaris owner with questions...

[d3r3k]

Howdy ya'll, i just took possession of my brand new 2013 Yaris CE. I traded in my 2010 Rav which i was not happy with at all. I was constantly taking it in for either warranty work or recall work, and it horrible on gas.
So far, i am very happy with my Yaris. Its sooooo fun to drive and I'm getting twice the milage that i am used to!
My only gripe is that i actually find the interior cabin relatively noisy. I find the tires very noisy. It almost sounds like the tire pressure is low, but I've checked and the pressure is bang on. I never noticed this when i was test driving the vehicle before i made the decision to buy.
Does anyone else notice that the interior is noisy?
