Exxon on the importance of tire air pressure

Frank -

I think I heard this on an Exxon-Mobil radio commercial too.

Hmmmm, I'm reading the fine print on exxpro and found this :

Reinventing the wheel

Keeping your car tyres inflated to the correct pressure isn’t just a matter of safety. It reduces stress and irregular wear. And, across an entire economy, it can also save millions of litres of petrol a day. That’s where Exxpro comes in, a recent ExxonMobil innovation that may revolutionize the tyre industry. A blend of synthetic rubber and nylon, Exxpro allows for lighter and more durable tyres that roll easier and maintain proper air pressure far longer than conventional tyres. These characteristics lead to vehicles that use less fuel and create fewer emissions.
...
Over the past years, ExxonMobil scientists developed a revolutionary new form of synthetic rubber, brand named Exxpro specialty elastomers. The material can be dynamically blended with nylon to form a unique alloy that combines the flexibility and elasticity of rubber with low air permeability.

Man, am I dumb. I thought air slowly seeped out of the schrader valve.

I agree that leaky valvestems tend to be the weak point, not the tire itself. What you're seeing there is typical oil company propaganda meant to favorably stick in the mind of the average consumer. This, however, should have been more clearly shown.

That would be truly awesome if I could get a lighter tire that rolled more easily, but could do the same job as my current tires.

Funny, the conservatives scoffed when President Obama suggested that every driver use a air pressure gauge to save lots of gasoline...

So we could each save between 2.8 and 4.9 gallons each per year depending on who's figures you use on the number of vehicles in the US, or an over all average increase in mileage of between .5% and 1% based off a 21mpg US car average.
