Self-inflating tire? Hope it works better than that damn low pressure warning system.

Great idea, but when we drive in the desert we need to defalte the tyres so we do not get stuck, we need the techonology to enable us to set the required pressure for the required condition (control the required psi)

The real need is for self inflating car tires.

Nice idea, but in the commercial sector, loads differ constantly, requiring (I guess, like in the passenger car market) different tyre pressures. Unless the tyres are intelligent enough to determine the weight of the load, it will be a pretty pointless product. Perhaps if the axle had some or other gadget that could determine the load and transmit that info the tyres which could adjust the pressure requirement, it would be a far greater benefit to the trucking industry???

didn't the oldschool "H1" hummers have self inflating tires?
Bruce H. Anderson
In the consumer sector, loads vary all the time as well. Somehow the tire manufacturers have got that pressure thing figured out. I believe this is a great advantage for trucks, whose tires are built for more miles than passenger tires, and are retreaded several times.

It is a good idea for use in commercial vehicles as the vehicles are very heavy. Would probably not make it to passenger vehicles. All the extra stuff that put into the wheels and tires would increase the unsprang weight. With passenger vehicles getting lighter and lighter to save fuel. Installing these types of self-inflating tires would ruin the ride and handling of the passenger vehicles

Need this for cars IE sales & rentals & Used models. A-Z makes. Must have feature.

re; idp
On road commercial tires, and car tires are designed to provide a flat rolling surface when the tire is at the specified pressure whether the vehicle is loaded or not. Unless you are overloading the tire, need to increase the ground contact area to increase floatation (you forgot about the on road specification), or need to lower the top of your vehicle to clear a low overhead keep the tire pressure at the manufacturer's specified pressure.

The H1 Hummers have central tire pressure regulation allowing the driver to adjust the tire pressure without stopping allowing him to maintain optimal tire pressure for the terrain in the specially designed tires.

The original HVM had automatic tire inflation, not self inflation. The axle was hollow and the compressed air came from outside the tire. This has the pump inside the tire.
This would be easy to make adjustable, by putting the pressure regulator on the inlet, which still looks a lot like a tire inflation stem, because it sticks out of the rim.
