Self-Regulating Tires Inflate While Rolling
By Alexander GeorgeEmail Author
We all know the consequences of driving on under-inflated tires: faster wear, increased potential for popping, and decreased gas milage. About half of all commercial vehicle breakdowns result from tire problems, according to the American Trucking Association, and tires are the single biggest expense for fleet operators. Since 2011, Goodyear has been working on self-regulating tires, and next year the company will begin testing its new self-inflating technology on commercial vehicles. If the system can handle the 100-plus psi requirements of big rigs, AMT (Air Maintenance Technology) will likely make its way down to passenger vehicles.
Here's how it works: A sensor on the interior detects when pressure has dipped too low. A valve mounted on the sidewall opens up, and as the tire rotates, the vehicle's weight compresses a tube built into the tire's circumference that injects air to increase tire pressure. Once it hits the optimal psi, the system shuts the valve and the ride proceeds as normal.
Add to this system compatibility with re-treaded tires, and it's an appealing package, especially for trucking companies. Goodyear hopes that with installation in commercial transportation, they'll be able to gather data to optimize the system for peak performance on the road.

I'm curious how they allow for delta-T during use?
When correctly pressurized tires are run they gain temperature and therefore 'pressure' due to rolling friction...
Also when the outside temps fall at night during non-use, the inside temps fall resulting in lowered 'pressure' of the tires.
Inside air temperature is relatively equalized during use regardless of outside temps...
Summer or Winter and ALL the other seasons in between.
So maybe, the little, itty, bitty internally mounted tire pumps are optimized at road use only... Curious. [:p]
a decent set of tires now costs more than many vehicles i have bought..this will add how much ??
if you have to ask, you don't wanna know. They've got a brand new multi million dollar building to pay for...[}:)]
My honest opinion is that if you can't take care of or safely drive your vehicle w/o input from electronic devices then you shouldn't be on the road.
Self regulating tires, self driving cars, oil life monitors, self parking vehicles--expensive crap that only works in the climate controlled lab.

So you drive a carbuerated vehicle with no electronics under the hood? No electronic ignition, no radio, nothing? Computers are a way of life now and have been for a while. The person who refuses to accept and work with the system, will eventually become a slave to it and become totally reliant on others for help. When there are no more cars available without computers, who is going to work on them? If you dont know what youre dealing with, you have to trust the mechanic. Ever met a dishonest mechanic? Dealer?
