Rubbing with Stock Tires and Stock Height?

On my '11 DCSB, when I'm reversing and at full lock, if I happen to roll over a hole or hit a speed bump the tires rub on something. Not sure what.

Is this normal? I wouldn't think so. Its full stock.

 

i do it in my first gen, stock height, stock tire size, and no offroad bumpers or anything weighing it down, wtf???

 

Yeah, I still have the mudflaps on and want them to stay on. Good rock chip protection. It's also why I bought a "4x4". LOL

 

yea, granted backspacing is out a 1/4 inch, but shouldnt thathelp???

 

X2 we pull the mud flaps off the trucks when we hit the trail (Those that have them) or they wont have any at the end or the trail.

 

or they just scratch the piss out of the truck. Like someone went over the area there touching with sand paper.....

My mudflaps ALWAYS scrape the stupid speed bumps here.

And off roading, they scrape on the ground..

 

Mine did the same thing with 265/70R16 BFG Rugged Trails. Full lock and compressed shocks. Now with slightly larger tires(265/75R16) it's a little more pronounced.
