Does anyone else with Zilla tires experience extreme rock throwing? I am amazed at the carnage constantly coming off them. Plucking rocks out of my headlight and fender assemblies. Sure wish I would have know more about their ability to pick, carry and throw rocks before committing. Do not mind them otherwise run smooth and have plenty of traction, just a bit destructive. Might need some sort of deflective shield near the headlight fender joint.

Yup same here with my Zilla's. But we have mostly sand here but I sometimes get on gravel roads and this is where I get into the rock throwing. I tend to slow down on these roads because of it. My Yamaha Overfenders help a bunch keeping the rocks under the bike, you might want to consider these.

You are going to get that with most any new tire, especially if it has recessed dimples in the lugs.

My reptiles throw any marble size rock they touch. And let me say, when it tosses them out in front of you and you catch it back in the face at speed.... It hurts, and it swells bad. I've taken a few to the lips and cheeks and nose.

X-2 with many styles of new A.T.V. tires, I didn't have too many rocks thrown ahead and high, and out the back was not big deal for me (those following learned fast to stay back:)) but what I got tired of was rocks coming up next to the floor board, bouncing of the rear fender and hitting me on the arm. I took on on the elbow that numbed my arm, so I bought a new horse trailer mudflap, I don't remember the dimensions but say 10"x12".....
I cut that in half long ways, and fit it to the outside of the floor boards as a rock deflector, and that knocks the rock out of the way.
I didn't want something hanging like we see on trucks, for it to do any good it has to be long and in reverse would get pinched and pulled off.
I don't have great pictures but these might help. I riveted them so they flop/flex and mud does not stick for long and pull them down.

Hang something flexible down behind the front bumper to block the rocks from fly ahead of the bike.

Yep they do hurt, sometimes fun to catch a lazy one with your hand on occation, just floating right there in front, but mostly sucks. Thats a good solution Ridgeway for the lower floorboard stuff for sure. They have really beat up my rear fenders just above the running board. But most of all they jam inbetween headlights and bumper/fender. So sounds like any aggressive tread is doing it then. I will try to protect a couple spots and stay in front. Hehe

Think about something like the rubber mudflap attached to the front rack bolt above the front tire(s).
It can hang down and touch the tire to stop rocks...and might look like crap there so you might want it further ahead...
Two cases of beer should get the idea sorted out...and a few more case for the installation. What's the downside?
As for those on the running boards, I got use to the mud splashing up at high speeds in the slush, but the rock......
