screw more psi in the tires.

You are the one the said you get better handling at 60 psi than 32. Don't back out now!

Uhm, because hypermilers don't report ANYTHING but MPG? And most of the cars that you use for your "scientific data" haven't been on the road long enough to see the damage you are doing.

Its pretty much elementary physics. You aren't absorbing as much energy with the tires = more energy gets transferred into the suspension and chassis. To completely write this off is irresponsible.

You are the king of fuzzy math, and that's my biggest problem with you. Ok, you save 400 dollars a year over the average, but that includes EVERYTHING YOU DO, not just over inflating your tires. 20 dollars may be low, but I'm betting you'd still have to go years to cover the cost of a SINGLE engine mount.

Please feel free to frequent other parts of the forums that are more in line with your personality and personal desires.

What mountains of data? I keep hearing about these 6 million miles of data, but I bet you don't have complete service records for any of the vehicles included in the data set.

And I like getting better gas mileage. That's why I post here. I just like to get the WHOLE story - not the tunnel vision story that hypermilers THRIVE on.

Tunnel vision applies to people who tailgate, race to the next light and drive only with themselves in mind. Tunnel vision applies to the sheep who follow without questioning and crying that the sky is falling anytime someone claims the earth is not flat.

People whom you label hypermilers can only attain optimal performance by paying attention to their entire environment, maximizing their safety level while enhancing their mpg.

You can say what you want, but until you have experience on both sides of the fence you're simply making statements with nothing to back them up but you're opinion.

Fact is, Brian is right and you're wrong. You don't have to accept that, but hopefully your ignorance will not mislead others interested in facts proven by real world experience.

For people who want to learn and not buy into conjecture; check out posts by Brian and check out cleanmpg.

WHAT FACTS? No tire manufacturer will recommend double PSI. No car manufacturer will. There are at least 3 people in this thread alone that have seen increased tire wear with increased PSI.

If a vehicle's tires are overinflated by 6 psi, they could be damaged more easily when encountering potholes or debris in the road, as well as experience irregular tread wear.

But its all a conspiracy huh?? I'll bet you thebarber and supmet work for the big oil companies.

No, I don't think the big oil companies would hire you to represent them and I fail to see anywhere where I stated double psi or conspiracy. You don't seem too hung up on being accurate anyways, so your misquotes come as no surprise.

If you actually did research and tried things out you could find the truth out for yourself. Posting a link from a reseller proves nothing. Believe what you want. I know I believe the over $700 savings in gas costs alone, and improvement in MPG by 15% since I started to slowly test, confirm and then apply the knowledge and techniques appropriate to my driving conditions and car, shared by people such as bailout. I'm also looking forward to seeing how many thousands of km's past mtbf I can go on my tires which show very little wear after 30k of 44-60psi.

...actually that's not true. A good tailgater drives at least two, maybe three cars beyond their victim. You have to have your empathy dailed up to ten to see where they might brake so that you can brake before they do.

If all you do is look at the bumper of the person ahead of you it's a matter of time before you feel it.

There are no good tailgaters!


I have very little experience with tire wear. I'm still on my original tires on my Yaris, and I had two sets on my old Elantra. When I first got the Elantra it had new Potenza G009s on it. I kept them at the pressure Hyundai recommended. After a few months the outer edges wore down quite a bit. My next set of tires were Falken ZE-512s. I played with the pressure until I found a comfortable psi, which was 40 psi. After 63,000 miles the treads had barely worn down at all.

I found the ride in the Yaris to be comfortable at about 42 psi on the stock Eagles. 9,000 miles in all is well.
