Heard a story on the radio today that Bridgestone is working on a new tire that has no air. The tire has plastic spokes in the side wall to support the weight of the car. Wonder where that idea came from? Dan
Yep, what goes around comes around, but you don't need plastic spokes...
everyone in the twenties just stuffed the tires with foam rubber!
p.s. Dan, received your reamer and inserts in the mail today, thanks....now to get a Stevens tool
I'm digging that lower ad. Why wouldn't those inserts work?
Ah, maybe they did for a while.
Then heat from friction, tire action, would cause that rubber to get gummy...then flat spots...til your T rolled to a stop and a bunch of globby goop pops off your tire.
Or, can you imagine when its freezing outside and those sponge rubber pieces get hard as the tire casing?
An auto tire needs air....freedom to rock and roll while on the rim...the fresh breath of easy riding on the boulevard.
A clincher is held onto the rim by tire pressure. You could never stuff in enough of anything to reliably hold the tire on. There was, however, also a foam-type rubber that was pumped in and allowed to harden.
I once saw a model T tire on a wheel at a swap meet that was filled with cement, then driven until the tread was nearly gone. I also saw a tire stuffed full of rags. It could probably get you home.
Drive carefully, and enjoy, W2
Michelin manufactures an identical product today for comptetition motorcycle tires. It's called the Bib Mousse Insert. Picture here:
They are also currently manufactured for Bicycle tires, too. Walmart sells them.
LOL -- The lower ad is a political statement --
NATIONALIZE YOUR TIRES AND THEN FORGET ABOUT THEM.
It is like "Nationalize the gas company and forget about ever getting gas again."
Sorry I couldn't help myself. The upcomming presidential campaign is getting to me.
Here it is
Is there any chance that mud or snow could get into those little holes, harden, and throw off the balance????
I have one on my wheelbarrow. I wore out 3 tires before I put this one on! Works fine on a wheelbarrow. Not sure it would work at the speeds of a car and with the torque of the engine and the brakes working on it though.
Charlie and Tom, isn't this a cut away view? If it is not I can't see where these would work to well in Montana. Or for that matter anywhere else you get off pavement or have snow.
Foam filled tires for agricultural use are readily available.
I've seen several versions of these tires and they're all open on the sides. I also wonder about the potential for noise from all those pockets spinning around.
Perhaps I've only seen prototypes and in real life they'll have some kind of flexible sidewall.
