The average motorist has a lot to keep track of these days. Whether its how much fuel is left in the tank, how much charge is left in the battery, or whether or not the cop behind noticed them checking Twitter, there’s a lot on a driver’s mind. One thing they’re not thinking about is tires, theirs or anyone else’s for that matter. It a testament to the state of tire technology, they just work and for quite a long time before replacements are needed.
There hasn’t been a major shift in the underlying technology for about fifty years. But the times, they are a changing — and new tire technology is claimed to be just around the corner. Several companies are questioning whether the pneumatic tire is the be-all and end all, and futuristic looking prototypes have been spotted at trade shows the world over.

[Jesus] apparently walked on water, without any tools at all. But when you’ve got a 3D printer handy, it makes sense to use it. [Simon] decided to use his to 3D print some tyres for his R/C car – with awesome results.
[Simon] started this project with a goal of driving on water. Initial experiments were promising – the first design of paddle tyres gave great traction in the sand and were capable of climbing some impressive slopes. However, once aimed at the water, the car quickly sank below the surface.
Returning to the drawing board armed with the advice of commenters, [Simon] made some changes. The paddle tyres were reprinted with larger paddles, and a more powerful R/C car selected as the test bed. On the second attempt, the car deftly skipped along the surface and was remarkably controllable as well! [Simon] has provided the files so you can make your own at home.
It’s a great example of a practical use for a 3D printer. Parts can readily be made for all manner of RC purposes, such as making your own servo adapters.
