Decrease your tire pressure 5-7 PSI for a 10% mileage improvement

ChrisHenry · 10-26-2007, 01:46 AM

Saw some text on a display selling tire pressure testers that said, "Decrease your tire pressure 5-7 PSI for a 10% mileage improvement". Seriously.

Yes, it really said that you should DECREASE your pressure to INCREASE mileaage. I read it several times to make sure I wasn't misreading.

I'm new around here, but have been doing some reading, and this seems to be ass-backwards. In fact, I was at Kragen to buy a pressure tester so I could increase my pressure as described in in Toyota Prius User-Guide that's posted on John1701a.com.

Any thoughts?

That display is f*cked up.

Agreed.

Do a bunch of people a favor: go back with a black sharpie and maybe some tape, and fix it. That display is so stupid as to be a liability given what tires do when they are under-inflated and run on the highway.

Pictures! Pictures! Pictures!!!

Ask them if the poster is for sale and let me know. <GRINS>

Actually 'Brick' is right about the safety issue. There were a bunch of SUV rollover accidents, many fatal, due to a tire inflation problem and weak tire. These were the infamous Firestone/Ford accidents. Seriously, I would pay for that poster (and a land shark would live for a decade on it!)

Why not ask in the tire store if they made a mistake?

That must have been a typo, or could you possibly have misread it? I was just in the Toyota Service Center today and was browsing around while waiting, and I saw a little display of tire pressure gauges (shaped like a little tire, dial-type readout, bleeder valve, almost got one, actually) and the display read "a decrease of tire pressure by 5-7 PSI can increase consumption by 10%", with smaller print underneath that saying that it could cost 2-3 MPG. I thought it said the same thing you posted and had to go back and reread it, got to admit it wasn't worded very well. If I had seen this post while I was there i would have snapped a quick picture. I remember those figures though, that's what caught my eye on the thread.

Hmmmm. Was it maybe ""Decrease your tire pressure 5-7 PSI for a 10% tire sales improvement"...

I was at the Fountain Valley, Calif, Costco tire store. I asked the tech to fill my tires at 42/40 for my Prius, and he just about had a heart attack. He went on and on about having pressures that high, and be sure to follow directions on the front door panels which states what pressures were for this Prius. I also asked if he had ever serviced another Prius before, and it was not a solid recognizable/understandable mumble.

You could have also asked him if he knew what the approximate burst psi is for your tires. (200-220 psi)
