Is it a MUST using inner tubes running slicks such as ET Drag 28x10.5, or Hoosier drag, QTP etc...?

 

i'm pretty sure you'd be flirting with disaster if you didn't

 

No you do not have to run tubes. Lots of guys (myself included) run slicks without them.

 

Whats the downside to not using tubes?

 

you run a slick? ie ET drag with no tube? et streets dont count as they arent really slicks

 

lol et drags and et streets are almost the exact same tire, same rubber compound and everything.....the streets just have tread lines for DOT approval and little stiffer sidewall, neither of which have any bearing on the use of tubes. But anyway, yes many people run et drags without tubes. If you have questions about m/t tires, go here and ask Jason:

-little more sway at high speeds
-air will leak out over time

If you run tubes, you really should run rim screws. If you don't screw them and the tire moves on the rim and moves the tube with it, the valve stem could shear off.

 

I have never ran tubes in my cars in the past.

drag radials have worked very good for me and many other way faster then my car

Butch I would really try to use a radial as the car will be faster over a slick.

 

it will eventually leak on you.
