Wheel + Trailer + Axles Sound v1.0

Hi there,

Here's a mod I've been using on private for some time and I would like to share.

Features
- Exterior and interior sound for gravel and grass (noticable mostly if you drive slowly).
- Interior and exterior sound of a mix of lovely SCREAMING truck gear axles and semitrailer tires.
- It does NOT replace any default or mod engine sound. It just adds background sound, so it should work with any truck, either vanilla or mod.

As a personal note, this gave me a new level of enjoyment on ETS2 because it ended that "muted" feeling when driving the truck. If you drive a lot in real life on highways as I do, you will understand what I mean (I love to open both driver and passenger window on tunnels to listen to trucks near me "screaming" :) )
