I stopped running tubes in my slicks about 30 years ago, my Fairmont goes 132 MPH in the 1/4 mile, with 10 PSI, no tubes, and no wandering in high gear. Now, if you have radial street tires up front, possibly that could be an issue, maybe. Also, you want to have the rim width closely match the tire width for stability. I went away from tubes because I found over time, the tubes would squirm around inside the tire and throw the balance, causing a high gear vibration. So after so many passes, I would have to take the wheels off the car, let all the air out, and shake the tires to allow the tubes to "flow out" equally again. And true slick tubes are natural rubber, which are heavy, as well as pricey. The weight of those heavy tubes can also negate the benefit of using lightweight wheels well. And if you get a puncture, a tubeless tire will generally go down slowly, but with a tube, will go flat much faster. Plus you need to screw the wheels to the tire beads, otherwise, even a minor amount of the wheel rotating in the tire, will rip the valve stem out. Although M/T says that you should run tubes in most of their slicks, very few people do anymore. Yes, you will likely loose air pressure thru the sidewalls over time, on my Fairmont, which usually runs 10 psi, if it sits in the garage 2 or 3 weeks, they may loose a few psi, not a big deal to me.
