Rotation and TPMS Initialization Questions

Sorry if this has been discussed before, but my searches weren't useful.

Since my dealership didn't rotate my tires for my 10K service as they were suppose to, I'm doing it myself. The manual says to do the rotation pattern on the far left of this diagram. I've always used the far right rotation pattern on my 4X4 vehicles, so each tire ends up in every position over the course of a few rotations. Can anyone explain why Toyota recommends the left pattern?



I'm also new to the whole TPMS Initialization thing. I find the manual a bit confusing. Can anyone give me a simplified step by step to accomplish this? Also, the manual says the initialization will not work on dirt roads. That's a problem for me since I live 7 miles from the nearest pavement. Do I really have to hit pavement before I can initialize the TPMS?

Thanks in advance.

 

I can't answer all of your questions, but if your tires are directional (you will find an arrow on the sidewall that indicates the direction the tires are supposed to go), then you cannot do a side to side rotation without unmounting and remounting the tires from the wheels.

 

Thanks, my tires are non-directional. I just did the rotation per the manual, but I'm still unclear why they recommend doing it that way.

I'm going to re-read the TPMS initialization procedure to try to make some sense of it.

 

When you reinitialize it will detect wheel location as you drive.

 

I always go front to back and never cross. Could be wrong but they don't wear or pull and the longevity is as expected per ratings. The truck will identify psi without doing anything to identify rotation change location.

 

Hmm....on page 479 of the manual is says "Do not fail to initialize the tire pressure warning system after tire rotation."

Then there is 2 pages, starting on page 482, that talks about initializing the TPWS. I never knew a tire rotation was so damn complicated.

 

I have always used the rotation pattern on far right with every car I have owned including my Tundra. Nice even wear and no cupping on outside edges. Tires stay quiet and don’t get louder as they wear. If you choose to just go front to back, thats another choice you can make but you will get more outer edge wear and cupping as they wear. It’s one of those personal preference things.

 

Guess I better read the manual! Thanks for noting the pages for procedure. Truck probably thinks it is living in yesteryear!

 

Thanks. That's been my experience as well, and why I questioned the manual. I'll probably go to back to that method the next time. It shouldn't matter on a non-directional tire, and I believe it is the best way to get most out your rubber.

The TPWS reinitialize is still a mystery to me. I checked the tire pressure menu on the MID after the rotation, and it showed all four tires with the correct pressure. Not sure why you need to initialize again. Apparently I'm one of the few nerds who actually reads the manual, and has an occasional WTF? moment.

 

I think is so the truck knows where the tires are located after the rotation

 

Same here. Rotated and did nada and 4 tires show with pressure. Magic!

Each sensor has separate ID which the ECM identifies. So no matter which location the TPMS is moved/rotated to, the truck will show by position the TPMS ID tire presure.
