To tube or not to tube?

[Nicholas Sloop]

I just bought a pair of almost new Hoosier Quick Time Pro 26 x 9.5. The seller said he ran them without tubes, although the are officially a "tube type" tire. These are going on a 13 sec 70 GS that sees track time once a month. Am I safe without tubes, or do I need to shell out another $90?

No reason for tubes, take some dishwash soap and wipe on the inside of the sidewalls to keep them from leaking.
I get my tire guy to put some black looking goop on the rim for a little extra grip after I wire brush the edge of the rim where the tire mounts.

Thanks
Did the dish soap thing, and taking them to the track for the first time tomorrow, then to BG!

Good luck, I run the 26x9.5-14 QTP on mine at 17lbs, they seem like they don't need a long burnout to hook good.......
