Gears

No, didn't recal my Odometer, but I have scanguage and can track the MPG that way. Plus I figure my tires have about a 7% greater circumference than stock, so multiply the miles on the tripmeter by 1.07 and divide by gallons it takes to fill = pretty accurate MPG calculation.

 

Your stock tires were probably reading too many miles (too fast) anyways, so now you're accurate on your mileage. No reason to adjust for tire size.

 

ok, great. so i guess i should go with the 4.30 over the 4.11 gears huh??

 

Keep in mind that the chart is old. Their figuring was done on a 3 speed automatic transmission, 1:1 ratio. Now we have 5 speeds and over drive. 4th gear in an auto would b 1:1 and 5th would be either .70-.85 .

 

Why do you say that, is the odometer/tripmeter off from the factory?

 

Yes. My truck (Sport w/ 265/65/17 tires) was about 3-4 mph off at 70 mph. So it would say 70, and I was doing 67, or it would say 75, and I was doing 71-72 (per GPS). I get about 5% taller tires (265/70/17) and it's spot on now. Search on it, it's probably one of the most asked topics on the board.

 

hopefully soon i will share that awesomeness

 

noo i think i want 4.56's, but everytime i look at your truck 37's are more appealing than my 35's

 

I think I will be doing gears very soon. Either 4.56's or 4.88's. Hmm...??

 

he already pm'd me and we decided 4.56 is better for me as i go on the highway often

 

This sounds almost exactly the difference of mine considering tire size. Comparing to GPS my mileage is 6.3% off and speedo is about 3 mph off and I'm running 285/75/16 so about half the difference from stock as what you are running.

 

I'd be VERY interested in hearing more about this. I have no idea how a spedometer and an odometer could NOT be connected. Again, my only experience is older cars, but how could the truck know how many miles you've driven without knowing how fast you're going??

 

If that's the case, yet another reason why I much prefer modding and working on cars without electronics. I'm not saying you're wrong (you're probably right), but it makes no sense to me why Toyota would do that. It would seem the most logical place to get miles driven information would be the speedomoter. But hell, what do I know?

EDIT: I found the explanation about converting the digital signal to analog, and causing the difference. Makes logical sense, but it's still a dumb way of doing things.

 

well won't you get better milage than with a taller tire?

 

sounds like it might be a little pricey... does your guy offer any warranty.


i was quoted 825 for mine so it seems like you paid a bit too much

 

i have 2 lol... 4x4

 

hit me up then!!!!!
