There is probably an industry guidelines for tire type and sizes. The amount of load on a tire and the corresponding the PSI are in those guidelines. It's Toyota's responsibility to pick a correct tire and recommend the proper PSI.

The weight of a vehicle does matter. If the Yaris was a 1,000 pounds heavier or lighter their might be a different tire or PSI recommendation. On the chart below for the Dodge Ram you will note that the front tires for a light load with the diesel require 10 to 15 PSI more than the V-8. Why? Because the diesel weighs a lot more. Notice when the truck goes from light load to heavy load the PSI for the rear tires go from 40 to 70 or 80. Why? Because as the weight increases there is an additional need to increase the PSI. There are some idiots that would put 120 PSI in the rears. Do you really think that "The.Tire.Company." made this chart for Dodge? More likely Dodge engineers figured the load for the tires in different situations and used the tire guidelines from the manufactures put together this chart.
This chart is for a 6 wheel Dodge rather than a 4 wheel Dodge, correct?

how do I jack up my yaris? I work at a auto repair shop...so...chassis lift on the toyota reccomended lift points....muahahahahah.

as far as tires...i wouldnt ever over inflate a cheap OEM equipment radial...thats just me though. I have worked at dealerships before and I have seen the results of over and under inflating said cheap tires. most tires wear evenly at 5-10 pounds under max pressure rating.

No. This chart is the Dual (6 tire) 1 ton 4X4.

The last post was for a 2004 3/4 ton 4X4 which weighs 7,000 pounds. I think the 1 ton is 500 pounds heavier.

Could anyone take a picture of how they jack up the back end of the sedan? The picture and the manual isn't clear enough for me to figure out exactly where this point is.

Anyone who has a digital camera, a Yaris (HB or Sedan), and knowledge of the jack points... Please post a picture of said jack points so Voodoo22 and I can verify the jack points on our cars??
Thanks fellow Yaris owners!!!

I can tell you two facts about tire rotation wear from personal experience and some engineering research:

FWD vehicles suffer significantly more wear to the front tires than the rear for three reasons: engine/tranny weight, steering wear, acceleration/braking wear (depends on the driver). Rotation will definitely aid in equalizing this wear between the 4 tires.

Modern steel belted radials shold only rotate in one direction, and do risk delamination/belt twisting when run on the opposite side of the vehicle, though the risk varies greatly depending on vehicle type, tire sidewall height and inflation pressure. Often the tire will not fail, but the lateral belts can become "curved" in the original rotation direction, and then resist flex in that direction when reversed. On larger tires (33" on my Jeep) this can result in a noticeable wave in the tread. Also, I have seen tires blow-out after being installed (used) without knowing the original rotation, although that could have been caused by a number of other factors too.

Bottom line: Rotate your tires regularly if you prefer to replace all 4 at once and want to get the maximum mileage from your tires. don't rotate at all if you don't mind replacing 2 at a time or don't care if 2 of your tires still have more tread left when you replace them.
NEVER cross-rotate modern radial tires, directional or not. :)

I think we may have to start our own thread on this as it seems this thread seems to have been hijacked by tire rotators

So it sounds like you are saying that tires have a mind of their own....or maybe even a computer chip that tells what side of the car it should be on??

The rear jack up point is 4 inches in front of the license plate. 1st picture using a 3 ton floor jack.

The side jack up points are between V notches close to the front and rear tires. 2nd and 3rd picture using the car jack. The cheapest car jack I have ever used.

The front jack up point is about 32 inches from the front bumper using a 2 ton floor jack. The 3 ton jack was hard to fit under the car. Remember to use parking brake when jacking up the front.

When I rotate tires I'll use the 2 & 3 ton jacks on one side of the car at a time. I don't think that I'll ever have the need to jack up the front or rear tires at the same time. These pictures are from a 2008 hatchback.

I think the Sedan is the same, it is just that the rear jack point is in the middle instead of more to the passenger side.

i just use the side jack point closer to the front of the car (behind the front wheel) and jack it all the way up....i do one side at a time for rotation.....

so rear passenger --> front passenger and front passenger --> to rear passenger then i do the same for the drivers side...

this way i only have to jack up once per side and it works whether you have direction tires or not....

Just installed winter tires on the Yaris, using a trunk jack.. I have a lift in my shop, but really hate lifting vehicles with no frame.. Pickup trucks are easy.. what would one use for lift points on a yaris.

^ same as the jack points. My car has been on a lift more times than I can remember. If you don't want to mess up that lip underneath, insert a slotted block to preserve it.
