255/70r17 MPG

I am getting ready for new tires and currently have stock 265/65r17 Bridgestone H/T. Want an A/T tire but do not want to lower MPGs. Anyone running 255/70r17? Thought this size should be a little better for MPG, since it is slightly narrower (less rolling resistance vs. 265) and slightly taller (slightly lower RPM) than the stock 265/70r17. I am very pleased w/ my MPG now (20 - 21 @ 60% city / 40% highway). I think this is very good for an '06 4x4 Tacoma and would like to keep it that way.

 

Yes, there are some here running that size.Welcome to TW.

 

Welcome to TW!

I doubt your mileage will be affected at all, for that small change.

I'm running 265/50/20 with a v6 & get around 20mpg on the highway.

 

I had a V6 2000 Prerunner and replaced the stock GY 265/75r15 tires with LT31x10.5 AT REVOs and I was never able to break 20MPG. Where as before, with the stock tires, I routinely got 20 - 21MPG with mixed (70% city / 30% highway) and 23 MPG highway. I have a '94 Jeep wrangler 4.0L with LT32x11.5 r15 C BFG TA KO and get 20 MPG highway. I don't think I could do better with another tire. It is disappointing to read about members that have gone to 265/70r17 and 265/76r16 BFG TA KOs and had a 1 - 2 MPG drop. Is there any member who has acheived the same mileage when upgrading to the 31.5" A/T tire? If so let me know, as I would love to get rid of the large "car" tires that came on my tacoma. Thanks.
