Yes. Are you in the diagnostic/service setup mode? i.e have you followed the procedure I gave you further up this thread somewhere? Mines a 10.

I've tried multiple ways prior to posting and I guess I just can't figure it out. I don't believe I am accessing the diagnostic mode?
Turns out I was lying to you all.
Hold down the 'Display' button and turn the parking lights off and on 3 times quickly.
Sorry, my bad. (my truck is 2010 manufacture)

Well ... you were only partially "bad."
In my 2013, I hold down the "Setup" button and turn on/off the parking lights 3 times and I access the diagnostic mode.
So, you were right, but didn't know it :whoops:
so if Toyota is building in a 5 percent buffer on the speedo, that's also true for the odometer correct? that would mean that for every 1,000 miles you drive the odometer would read 1,050, meaning your truck would actualy read more mileage than you have actualy put on it, meaning your warrenty term etc would be cut short, is this correct? And by adding 5 percent larger tires on your truck you simply make all readings accurate? just seems kinda strange, am I missing something? Funny thing is on my way home from work yesterday I drove past one of those radar speed things and my speed was exactly on, and I have 265-70 R18's on my rig, so I"m now right on with the larger tires

The odometer and speedometer do not exhibit the same error. With my stock tires, the speedo reads fast, but the odo reads accurately. But with my larger tires, the speedo reads correctly (just a little bit slow), but the odo reads dramatically fewer miles.
So my experience shows that Toyota are fudging the indicated speed, but not the mileage with the stock setup - we ar not getting fewer miles on our warranty. But with the larger tires, the speedo readout is much closer to correct and we are indeed "stretching" our warranty due to the fewer number of miles recorded by the odo.
Slightly less than 33" tires (32.8"?) seems to be the sweet spot for accurate speedometer readout.

PERFECT, so with my new tires my rig looks way better, my speedo is now correct and I extended my warranty
