Tires, my secret sauce formula. - Page 5

It's fine if you can't get equipment to measure things, we're just saying that until you do you should stick to the measured results of other people and not claim your own testing as factual.

j5e: I think it's been decided on here that the tire doesn't bow out, therefore reducing contact patch, because of high pressure, since the steel belting in the tire prevent the tire from physically growing in size, as the steel doesn't morph enough to make that difference.

Also, some have claimed greater traction with the higher inflation, and a police article has also claimed this to be a fact.

SVO: I wonder what the condition's were where they measured. I would think that their would be some kind of variation, where if you went high enough you wouldn't have enough physical rubber on the road to take advantage of the traction available, but at some point as you lower the pressure the sidewalls would become more and more flexing, to where the side walls would heat up and the rolling friction would go up.

Do you have any link to the police article?

Compaq888: I know you don't have a scan gauge, but I appreciate you sharing the information you had, anyway, as I presume everyone else did. From my perspective, my bottom line is that I am not paying nearly what I was, at the pump, every time I put in gas, for every mile I drive. If your paying less, than you were when the tires were at 30 lbs, then I wouldn't change them back.

The police article is somewhere on the site. I lose track of things too easily, I think dan posted it so mehbe he can help out with that. I believe their reccomendation was 45-50 psi in a crown vic with max sidewall pressure of 44.

At your service.

As you can see in my gas log the more I increased fuel economy the more my mpg improved. This is not just the 3 tanks.

i only see tanks since november. large climate changes since then and from your data it seems like your coming from the neighborhood of 28mpg from that time, which is still cooler than it is now. i dont see anything but fuzzy logic.

OBVIOSLY

you know your mpg is a statistic right?

30-28=2.... that sounds about right.

I told you before i started this mpg thing I got 24mpg constently. There was no gas log so I just threw away the receits because I couldn't enter my data.
