the bmw m's come with no spare and a can of fix-a-flat. it obviously gets you to the shop so u can replace the tire. it's a convenience item so you dont have to wait for a flatbed. i don't really care about the 15 year old who takes the old tire off, since it can be hosed out and either patched or a new tire can be put on in minutes time. also most tire machines are in garage bays, so why wouldn't the doors be open. the only way it's toxic would be if you inhaled it in a closed shop, or if the slime kind were toxic and got on your skin.

 

i assume youve never used a tire machine before or you would realize that your not trying to scratch the wheel so your face is about a foot away from the bead of the tire

ever weld galvanized steel? doesnt matter if your outside you can still die from breathing it in...

 

you get a nice puff when you break the bead with the bead breaker shovel.
