I searched and didn't find much on this.

On a 600+ HP truck running 30" MH DOT slicks on 16" Bogarts do I need to secure the tires to the rims? Screws? Beadlocks? Tubes?
Any input would be appreciated.
Thanks

 

I would use tubes. From what I have read, anything over a 29" needs tubes.

 

If you use tubes you MUST use screws. You don't have to use tubes and if you don't you can still screw them to the wheel as I did.

 

I would say at that power level YES you want them screwed, I have mixed opinions on tubes or no tubes, personally I prefer NO tubes but tubes will hold air a little longer in the event you puncture a tire (which I wouldnt want @ 140 MPH ; o()

Fast Freddy showed me how his slicks moved on his rims recently and I've seen others move at less power than your talking so in short the answer is
"SCREWED"
