With your knob tires, you will be throwing rocks and debris every where = more paint damage.It's not your thing and totally understandable. In my case though, I've done more damage on the road, then off.
Also, yes just the thought of having to clean it terrifies me!
It's ok, my boss is a backwoods guy with a chevy 2500 gasser and gives me **** too. I always respond he can talk all the ****, but just remember my "little" truck makes more power and will pull yours all day! Gets him wound up.
