Yep this is my understanding also. The reason tires are black is because they do add carbon so they don't look dirty. Well back in the day anyway, today well no idea if tires are rubber at all, they really are a Marvell of science, if you really think about it. Red was probably just a marketing thing to draw people to the tubes. google: ford model n Rubber is white. Last edited by Tinker; 07-02-2018 at 10:26 PM. |

Re: Red inner tube
I still run across red tubes in old tires and rims from the 20s 30s and 40s. Like has been said some of them still hold air.

Re: Red inner tube
That’s cool that there’s still aNOS one around. Don’t think I trust a eighty year old tube though. But who knows, might out last the modern stuff.

Re: Red inner tube
Tires and tubes need flexibility and a lot of it. Carbon black was added to synthetic rubbers to get more tensile strength and plasticizers are added for more flexibility. The ingredients just happen to make it black. Natural rubber already has an inherent tensile strength and flexibility when certain additives are added prior to vulcanization but they can't grow enough rubber trees to meet the demand.
The military did studies on the best "formula" for synthetic butyl rubber for aircraft tire tubes way back when and found that there is a bit of a trade off in the mix they chose. They wanted something that could take a lot of heat and also still perform well under very cold conditions. This wasn't an easy task to fulfill but the trade off works well enough in both situations to get by with some measure of reliability |

Re: Red inner tube
I honestly don't know what's the big deal about red inner tubes. Back in the day, they were as common as dirt.
Hmm... Maybe that's why when I flirt with the cute girlies at the grocery store that they giggle and tell me I'm old as dirt?
