Snail Tire System

Tires exude substances onto road surface for traction, action and satisfaction.

Bicycle tires, despite their often large circumference, only contact the surface of the road with a fraction of that. Enough pressure is exerted on the contacting portion to open up some valves. These valves will run the circumference of the tire.

Inside the circumference of the tire rigid pipes will run. These pipes will continue up the spokes to the wheel hub where the pipe will continue to a reservoir after passing through a rotating joint.

The reservoir can contain numerous viscous substances. These can include jam, beeswax, custard, fishbone glue, and custard if so desired. However, the main substance classifications would be lubricating, inflammable and adhesive.

In order to perform sweet skids, leave a fiery trail, or ride on the ceiling pull the appropriate lever and exude the substances at will.

       As a rule you don't want greater cohesion between road and wheel, as it increases rolling resistance. A slight boost in a high speed turn would be useful though.

       //you don't want greater cohesion between road and wheel, as it increases rolling resistance.// But what if "cohesion" is a tensor? Is there a goop with low tack, but high resistance to shear? Would that increase traction without increasing rolling resistance?   

       Custard jokes aside, how would a thixotropic material behave? Does the following work?   

       Consider a patch of rolling, oobleck-secreting tyre in contact with the road. Might not viscosity be greater at the leading edge and middle portion of the patch, than at the trailing edge? If the tyre had treads (and, of course the road would have crevices), the temporarily thick oobleck would act like gear teeth, increasing traction. At the trailing edge of the contact patch, the oobleck'd loosen, and the tyre'd lift fee of the pavement, without resistance from disengaging "gear teeth."   

       Might only work at certain speeds, though. In addition to a gear-shift lever, you'd need a lever to adjust which grade of thixotropic goop your tyres oozed.

       How much gloop were you thinking of carrying? Even if you could limit the layer to 2 thousandths of an inch thick, 3/8" wide, 1oz would only last 60 yards. That's 30oz per mile. A lot of gloop to carry, along with the distribution system.   

       How often do you lose traction on hard surfaces? (Obviously, gloop won't work on loose surfaces).   

       Also, how far would you get before your tyres were a mass of gloop and adhered dust, litter, small animals, innocent bystanders etc?

       I like the sensation of squeezing the right brake and skidding when I turn corners, but it wears the tire down. That's when the idea occurred. It was just an idea to stop the tire from wearing down.
