I'm getting ready to buy a set of slicks for my 72 Challenger.
28x10x15 in size going on a set of Jegs SSR Star wheels.
Challenger will race only a handful of times a year and will be in the mid to upper 11's.
Which is best? slicks that need tubes or tubeless?
Thanks for your help in advance.

If you're going to use beadlock rims or screws, I'd use tubes. If not, go tubeless. Your mileage may vary.

I've run M/T, Goodyears and Hoosiers. I've run a 29x11.5 (11.50 car) and 31x14 (10.70 car) tire on my 2 cars (Dusters). I personally prefer the M/T with tubes. I've ran both cars with and without tubes and the cars run the same and are just as consistent, but for whatever reason my reaction times seem to be more consistent when I run tubes. I also think tubes help the sidewalls last longer as usually the sidewalls wear out before the "tread".

I used to run tubes on my real slicks, I would put baby powder in the tires so as to not let tube stick to inside of tire. I also screwed the tires to the rims. With my street slicks like M+H's I ran tubeless but still screwed to the rim. Some friends would coat the inside of the tires with liquid dish soap claiming they had less leakage.

I've always run tubes in slicks for two reasons. One is the tubes keep them from leaking. Two is the tube makes the sidewall stiffer which is faster and they last longer.

If you do run tubes, you HAVE to make sure the rim doesn't spin inside the tire or it can tear off the valve stem. I've always screwed them to the rim to prevent this from happening. You can also use hi-tack adhesive on the beads when you mount them, but screws are more secure IMO.

Baby powder on the tube when mounting the tire keeps the tube from getting folded up and "lubes" the tube inside the tire to keep it from rubbing.

I run Mickey Thompson slicks, their tech info says they will work better with tubes. I have always run tubes. As mentioned baby powder or corn starch so when the tire wrinkles it does not pinch the tube. And baby oil does work to keep them from leaking with out tubes, I use baby oil on my front tires.

I run tubes also with my slicks. I like the additional stiffness for the sidewalls.

I prefer tubes for the reasons already stated. The ones I use have a threaded stem so they're attached to the wheels. I also screw the slicks to the rims, both the inside & outside faces. I've run 'em as low as 6 PSI (as an experiment - no advantage found) on a low-10s Duster (13x31 slicks) and no problems.

I use to race NHRA stock back before radial slicks where out, we always ran the bias ply slicks tubeless with screws in the rims to hold them onto the rims to prevent them sliding around.
I have ran the M/T Et Street bias ply tubelless as well as the same size M/T ET Street Radials, the radials where faster on a good track but would spin really bad on the street
On your deal I would choose either Hoosiers or Good Year slicks in what ever their tech. guys reccomend on the construction, bias ply or radials, for your car and use
I think M/T is the only company still making tube type bias ply racing slicks
If you decide to run slicks they have to be true rubber racing tubes, not standard automotive local bought from a tire store cheap street tubes
All the drag race tire makers make stiff wall slicks for the cars that really need them

Thanks for your input everyone!
I like M/T and I think I will get tubes with them.
I haven't thought of screws. Probably not a bad idea.
Thanks again!

No tubes and use Permatex on the bead. Also coat the inside with dish wash soap.

No tubes for me and I also don't run rim screws any more. My car can sit from December to late March and they don't leak any air. Ron

From Mickey Thompson's website regarding screws if you run a radial tire.

Also, the tubes such as what you get from MT, may require the rim's valve stem hole to be enlarged.

do you run screws? and can you or someone explain what to do with the permatex and the dish soap? thanks

The race tubes are really heavy, a lot heavier per tube than a regular car tube is!

I haven't used a tube in any of my race cars for over 30 years.

I ran no tubes for years. Wiping dish soap on the inner sidewalls (heavy coat) most times will keep them from leaking. Apply liberally with a sponge. Gluing the bead to the rim with purple Permatex keeps the tire from spinning on the rim. Works good. I now run tubes with Permatex. Been as quick as 1.24 60 ft. My car needed the extra stiffness provided by using a tube.
