Radir Pie Crusts: Inner tubes or no?

Got a set of Radir WWW Pie Crust cheater slicks. Based on your experience, do I need to run inner tubes with them, or no?

Thanks

tubeless bro- they are a 1 piece design with modern rubber

 

Tubeless,,,,,,,, but if your worried about leaking a trick is to take dawn dish wahing soap and coat the inside of the tire and let it dry to a sticky kinda film before mounting the tire.
That's always how i have my skicks mounted

 

I agree tubeless as they are made on tubeless tire cores. Even real drag slicks can be tubeless, I used the dish soap trick just like 12pack described. They still lose air, just at a slower rate.

 

Cool. Thanks guys.
