why cant car tires just be fully rubber so they don’t become flat?
The advantage of the air, I think, is that you feel the bumps a lot less. Of course, you could also fill them with helium, which would make the car lighter, and save you .00001% in gas.
Ask and you shall receive. Michelin just opened a plant to make airless tires. http://www.gizmag.com/michelin-tweel/34909/
Technically it’s not airless. The spaces you see in the pic are filled with air.
Pneumatic tires suck. Thanks to the cold weather I have a tire pressure warning on my car. I would love any alternative that matches or exceeds performance. Would love to never have to worry about a flat or under-inflated tires.
I’ve learned one benefit when your changing driving conditions such as on a race track or dirt roads is that you can either increase air pressure or lower air pressure provide better traction… I’d love an all rubber tire design that never goes flat but I guess it wouldn’t be adjustable right?
