Based on the above, you don't need/want tubes or screws for that matter. You may however need to adjust your tire pressure, shock settings etc. initially after making the change. FYI, mount your slicks DRY, meaning without mounting solution.
Can you run Mickey Thompson slicks without tubes?
Never run tube type tires on the street without a tube. Leakage and the prolonged heat build up can lead to tire failure, serious injury or death. This is not a matter to take lightly. Check the valve stem hole in the rim.
How long do Hoosier drag slicks last?
They told me they have a 2 year shelf life but their distributors dont rotate stock back to them if they get old so you might get an "old" set even if they are new.
