Back in March I bought a 05 Tundra Double Cab. The second day I had it, I took off the stock 265/65R17 Dueler H/T on the stock alloy wheels for the 265/70R16 Revos on Wheelers black alloy rims I had on my 4-Runner.

My logic tells me the H/T's will give better MPG than the Revos. Am I thinking right?

 

Nope. the 265/65/17 is equivalent to the 265/70/16 in size (basically) ... and any difference thereof will not result in any noticeable change in MPGs.

 

How about tred design?

 

MPG is something mostly effected by size ... you will not notice much of a difference since both tires are nearly the same size. what are the ODs of each as per the manufacturers' websites?

 

265/65R17==30.6 diameter/96.0 circumfrance/660.0 revs per mile
265/70R16==30.6 diameter/96.2 circumfrance/659.0 revs per mile

We are talking a 0.1% difference in the speedometer, so the odds of you noticing anything or it having any effect are virtually zero.

There might be a slight difference if one tire has a very agressive tread and the other a street tread, but again, the odds of you detecting it are slim.

 

That's what I needed to know.

I love the way my truck looks with the black wheels and Revo's and don't really want to put the stock tires back on.

Thanks,

265/65/17 Dueler HT = 30.4" OD
265/70/16 Revo = 30.7" OD

so again, no, you will not notice a difference in MPGs with that .3" OD difference. and those measurements are from the manufacturer's website which takes into account the tread, etc.

 

Tread design can make a slight difference in mpg, but Revos do not have an aggressive tread so that won't be a big factor either.

 

blue,

i made the same change too. for a year or so before i got my gps, i noticed that my mpg dropped. however after doing a visual "calibrating" and comparing my speedo to my gps, it turns out that w/ my 32s, the speedo is dead on w/ the gps speedo. this tells me that my mileage w/ the stock 31s was artificially reading higher

(i hope my logic/math is correct)

Thanks for the info.

The size of the Revo's I have now are a stock size for my truck. I wasn't concerned about the size of the tire but tread of the tire. The Revo's look more agressive but from what I am hearing, I won't see an increase in MPG.

So, I can keep my truck looking cool.
