that is the question? well im tired of flating my rear tire and i dont want to add a 10# DH tube so i was thinking about using the Stans No-tubes freeride/DH set. is this product worth doing or should i just stick a thicker tube in the rear shut-up and just ride?

I've been tubless on my big bikes for the past year. I've done a lot of experimenting, so far it's working well.

What tires are you running right now?
DH casing?

For DH I'd recommend Maxxis Minion/Highroller 2.5
For FR the Maxxis Advantage 2.4 (non-UST) seem to work well and are a lot lighter than a full on DH casing.

Stans works great for me. At least untill the tire starts to wear and you rip knobs off. Then it's tube time.

maxxis mobster 2.5 DH case wire bead front
maxxis larson tt 2.35 DH case rear wire bead

my only concern is that im at the 280# mark and was wondering how the tire will stay attached to the rim without the tube.

im running salsa gordo 36h rims (32mm wide i think)

Same way they do with a tube - the tire bead.

If you run a reasonable pressure, your weight isn't an issue. Agressive riding puts way more than 280# of force on a tire through turns and rocks. The dirt aught to give before the tire does, otherwise your not running enough psi.

the less $$ way to go tubeless is to use 20in tubes, cut around the outside(for a rim strip), then buy a quart of stan's sealant. you can use schrader or presta this way. the cut tube will stick out between the tire and rim(cut excess). run 5-10psi more than with tubes.

I think the ghetto tubeless is better than stan's because there is more contact between the tire and rim strip= less likely to burp.
