#311 of 472 psi overkill by walterquint Feb 08, 2008 (8:08 pm)
To anyone who is inflating their Yaris's tires to 44 psi: I say to you, please desist!! It's potentially very dangerous.   Like most people, I usually inflate several psi higher than the door jamb sticker. That means 35psi for my Alero 4cyl. But 44psi is really pushing the limits of the Yaris's tiny tires. Plus, you're promoting premature tire wear because less of the tread is touching the pavement at that pressure.   Finally, and most importantly, you're seriously risking a catastrophic hydroplaning event!! The Yaris is light enough the way it is; with super-pumped tires, it'll skate over a rainpuddle and land you in a ditch. Please, the few mpg you save aren't worth your life.

All one has to do is lookup the actual facts. Not opinions. 44psi is stamped on the side of the tire so that one knows the load limit and psi ceiling that is perfectly safe to use. Every tire sold, has that data on the sidewall for a reason. That reason is safety. There is no reason not to inflate to maximum pressure if that is what one wants to do.

Replying to: podred (Feb 10, 2008 9:54 am) Thank you podred. I agree with you. On two gas saving webpages, which I am not allowed to show here, most are doing the max shown on the sidewall. None are having problems, and all are getting better mileage. I do not think there is a safety problem with going up to the max on the sidewall. Tire wear is normal.

Replying to: fastrunner (Feb 10, 2008 11:22 am) For liability reasons, the tire maker is not going to post an unsafe maximum PSI on a tire that he manufactures. Enough said, one less catastrophe to worry about.

FYI: The information posted on the sidewalls of all passenger cars is federally mandated. It's the law. Period. There is not a single tire maker that is going to risk the liability, law suits, and ruiness reputation that would result from posting false info on their tires.   One of the greatest causes of premature wear is underinflation. All one has to do is walk behind the tire store to the pile of tires they have removed when installing new tires. You will notice that the very center of the tread surface has at least 50% remaining while the shoulder of the tire is bald. This is what you get when you run the _auto makers_ suggested pressure. (Not that of the tire maker). They do not care how much tire life you get, they just want to you experience a soft ride. Believe me I used to own five tire stores. I know of what I speak. I have no reason to mislead you. Do yourself and your wallet a favor. Run at least 5psi more than the pressure indicated on the door sticker. You will increase your tire life by at least 10,000 miles, minimum. Check them once a month and you're all set.   Cheers! Replies to this message: dgecho1 (Feb 17, 2008 4:19 am)

#317 of 472 Finally a road trip... by dake Mar 03, 2008 (5:57 am)
So we finally had a nice little road trip for the Yaris. For the record: Auto Sedan with 2000 miles, sport kit, cruise control and average spd of 70 to 75 mph on mostly level highway with AC on the whole time, managed to do 36 mpg. I honestly expected maybe 38, as my Auto Echo did the trip and made about 41mpg, but still not bad and a bit more comfortable for the ride. I love that I can stretch my legs out straight in the Yaris - I can't quite do that in the Echo.
#318 of 472 Average HIGHWAY MPGs ? by katmandu2 Mar 08, 2008 (2:45 am)
So what is the AVERAGE MPG for a Yaris ? Replies to this message: podred (Mar 10, 2008 2:26 pm) dobekeeper (Mar 28, 2008 6:08 pm) podred (Mar 29, 2008 3:00 pm)
#319 of 472 Check out the FUEL LOG on GasPrices.com by katmandu2 Mar 08, 2008 (2:46 am)
There is a GREAT way to track your Yaris's fuel mileage/usage On-Line!    Go to www.GasPrices.com and use the FUEL LOG feature.

Replying to: katmandu2 (Mar 08, 2008 2:45 am) This is a great question! One that varies widely, depending on a several variables. 1) Is it a Sedan, or Hatchback? 2) Does it have a manual or automatic transmission? 3) How heavy is one's right foot? 4) Flat terrain, or hilly? 5) City, freeway or mixed? 6) What percentage of mileage if mixed? Obviously a topic that can be discussed for a very long time.   Bottom line, what I use as an indicator when buying a new car is the Fuel Economy Numbers on the Window Sticker.   Why? Because the one thing we do know is that all new cars of the same model year are tested under the same conditions. Therefore, while your mileage may be greater or lesser than what's on the sticker, at least you can compare one car to the next with the peace of mind knowing they all went through the same test.   Cheers!
