If you run tubes, you run screws or beadlocks.

If you think you can get away with running no tubes and still manage the wheelspeed (sidewall), don't worry about the screws or beadlocks.

It's not a one size fits all topic.

Baby powder will keep from the tire pinching the tube, it won't keep the tubes valve stem from disappearing (breaking the tube), in the event the tire turns on the rim.

Nose heavy car with a lot of torque BBC, on a small tire, I'd run a stiff sidewall and a tube, exactly as I did.

It's a tightrope. Why practice falling, when you don't have to.

Falling is a waste of time, energy and resources.

Without screws on my S10 the tire would move about 1" to 1-1/2" in a 7 to 8 run day. They needed balanced every other week. I put screws in, 10 per side, and have never had an issue. Screws were a lot cheaper than beadlocks and accomplished the same thing on a smaller budget.

I put beadlocks on my current car because the old wheels were trashed from screws, I wanted beadlocks, and it makes changing tires so much easier. When I raced my Nova back in North Carolina, I didn't originally run screws, but I was running tubes. Just a slow 6.7xx 1/8 mile car, but every pass the tires moved on the wheels...screws stopped that... Honestly, if it was that much of a concern for me, I'd run it and see what it does. It's likely they might move a little at first, then stop. If that's the case, you're good. If not, then I'd sell the wheels and do beadlocks instead. But that's just me.

I've run that same tire for many years, last 2 years ran with tubes. Didn't slow down a bit and felt it repeated better with tubes. I'm around same power and speed. Oh yeah screws too, works for me.

Did you every try switching the tires side to side and see if they went back to original position?

You mount them dry and they don’t move. Hit my tires with a whole lot more power than you and the OP.

Further, it’s the year 2023, no one runs tubes that has a clue. Most bracket racers haven’t run tubes in 30 years.

Here’s one disadvantage using tubes. If you pick up a screw, nail, or other pointed object in the tire, you’re forced to remove the tire to repair. This is something that happens more frequently than one might be aware of.

If you carry an inexpensive tire plug kit you can be back on the track in minutes. I’ve plugged a rear and a front tire for other racers in the staging lanes. I’ve found screws 2X in my rear tires the past 15 yrs, plugged them, and ran them the duration without problems.

I keep one of these tire kits and a 12v air pump in my truck just in-case.

I’ve been doing this on my tires and friends for decades and I’ve done it in the lanes. Get a puncture in slicks with tubes and you’re done for the day.

No screws. first pass my tires move less then a 1/8 then they never ever move again Been a 1.24 at almost 3000 lbs 32-16 tire. No tubes or screws its not 1970 anymore...

markemark,
I did rotate them a couple times and they moved about the same mount the other way. I am not going to go to the work to rotate slicks every weekend to keep them balanced, too old for that ;-)
I did mount them dry, didn't seem to help. Thinking back I should have roughed up the bead area of the wheel with an air chisel to make a "serrated area". Screws are in, no problems since.
As for rotating tires??? I have a new way of doing that, I rotate them when some grain starts to show, been about 60-70 runs last summer. Not sure it is even necessary, old habit I think.

I’ve mounted my slicks dry for 20 years, never “roughed up” the bead, just clean with acetone. Never moved and I never rotate my slicks .

You do not want slicks to move. They do need to be clean before you mount them and that Red Permatex Sealant seems to work good. A lot of people around here use it. Put a little on the bead when you mount tire it dries quickly and works.

I did not want to put screws in my nice wheels and Permatex fixed it for me. But if you slicks are moving you going to have to do something whether it is trying the red Permatex stuff or wheel screws.

Again, NOTHING is required to keep the tires from moving on the rim without screws except to clean both the wheel and tire’s bead with acetone and mount them DRY.

Who the **** uses tire tubes anymore.

Only the clueless

Cleaning the rims before mounting the new slicks makes a difference. I did have a set that moved on the rims and broke them down, cleaned real good and sprayed some hair spray on the bead before seating. They never moved again. For $1 it's cheap insurance and it's no mess like permatex or some of the other fixes.

I had a customer last year take his car out and i`m watching it leave the line and it looked like the tires were bouncing all over the place. I asked him whats up with the slicks. He said i dunno, they`re new with new tubes. I looked at him and told him to get the tubes out asap. That is 80`s technology. The next week the car 60ft better and drove better down track.If you`re running tubes, you have no idea what kind of performance you`re missing.

Yes. I run tubes too..

I think the moral of this story is:

If you run tubes, you need rim screws.

If you do not run tubes, rim screws are optional but certainly not required. Just clean the rim and mount slicks dry.

I will add, if you run Hoosiers, no soap is needed on the inside of the tire. Just fire them on clean rims, air up and go racing.
