Tube or no Tube

I would like to hear your opinions on this . I'm getting ready to mount a set M/T 28x 10.5 15
slicks on my 67 Dart for drag racing. One man tells me run tubes the next says to put in bolts.
The wheels are already drilled and have bolts in them. M/T says run tubes, I have M/T's on the car now without tubes and have had no problem. I am stepping up hp at the same time. Any thoughts would help. Thanks

If u run tubes, and get it hooked up, w/ a lot of h.p. , u better screw them too . The tires will turn and tear the valvestem out of the tube. Ask me how I know !!
