i feel bad just throwing it in the garbage

deathhare

Toss em in the river, of course.

I use old tires on the trainer or if they are too far gone I cut boots out of them. Having one in the seat bag can be a life saver.

I patch tubes.

bonechilling

I think that REI collects old tubes for recycling, but that might vary by location.

freeskihp

I melt them down and make water-proof underpants and flippers

dayvan cowboy

last tube I changed, we played ring toss with a streetlight on my campus when we were drunk. Don't know what happened to it, it was gone next time i walked by.

ryanlovesyou

I think I've patched my front tube at least 20 times.

BLIMP

Burn them in the oil drum in my front yard with all the other garbage.

MIN 

Take an old tube and cut a 4" section out of it. Wrap this around the seatpost collar and post to keep the gunk out of the tube during the wet seasons.

RaeFixie

you can make belt out of it =]

Old tubes make shock cords and 5 old tires were recently exchanged for water bottles in a Specialized promotion.

ThunderChunky

melt them down and eat them like i did with my old shoes.

bottom-bracket

I give old tubes to tree climbers to use so there ropes don't cut the bark

nathbdp

smoke the rubber

ThunderChunky

butt floss.

orangepaint

I use old tubes as bungee cords!

RhinoRiot

once your butt has been flossed, and you are up to your ears in bungees - many 'specialized' dealers are accepting old rubbers (sans trojans) to be recycled.

Legalize It

I use to drop off my old tires in a free box ourside of my fav bike co-op in Portland, The Bike Annex on 17th Ankeny.

And tubes **** id throw em away. I really should patch them though.

dddave

i always patch my tubes. tires i just toss. i should probably recycle them somehow.

twobikes

I had trouble with my tire liners making abrasions in the cords of my tires and in my tubes. I cut about 4 inches from an old tube and slit it lengthwise. I made two of these for each wheel. One went between the liner and the tire at the overlap in the liner. The other went between the tube and the liner at the same place.

Some have said in similar threads that they use old tubes for tie down cords on roof racks, etc.

I do not have a use for old tires.

darksiderising

I save them for times when I need to carry large/awkwardly shaped things to work or school. Rig up a sort of backpack for them.

NitroPye

I've been toying with making a cell phone holster or some kind of pouch, generic holster out of my old mountain bike tires.

WhiteCarbonDude

Donate them to Totally Tubular Designs so they can turn them into handbags and purses.

TehK

One of My LBSs gives you a free tube for 10 you bring in.
