Upsizing to 265/70 R17

I have a 2016 TRD off-road...I am thinking of switching to trd pro wins and upsizing the tires to 265/70 R 17.

Has anyone done this? What should I expect with ride and fuel mileage?

I know the width will stay the same and the height will increase by one inch.

This question is being asked by someone who commutes 150 miles a day with with 16 trd off road manual shift.

 

I did this on my 1st gen a long while ago. Your speedometer will be off by a little, but not enough to matter. You may lose an MPG. You may also rub ever so slightly in certain scenarios (full lock over a speedbump).

TL;DR: It's pretty insignificant.

 

I've been using 265/75/16's for a long time. For all practical purposes they are the same overall size as 275/70/17's and are about 1" taller than stock tires. There was no difference at all in fuel mileage or performance. If you go to an aggressive tread pattern it might make a small difference.

 

Thanks for the comments...

Do you know if the trd pro rims will bolt right on with the factory nuts?

 

Anyone know if any rubbing issues going the +1 size 265/75/16 on stock suspension with the Toyota mud guards?

 

Running that size and no rubbing, but have a friend running 265/70r17 on his sport and he is rubbing stock. Mine didn't rub stock with 265/75r16 and now have a mild lift on. Still no rubbing.

Both of us are running the same tires. Fallen wildpeaks at

 

i run 265/70/17 and i get about 18mpg. But my commute is kinda odd, where i go through a short mountain pass and onto back roads. And yes your factory lugs will work perfectly fine.

im on stock suspension and i dont rub at all. I did however remove the front plastic splitter thing

 

265/70/17 Cooper STT Pros on 4Runner rims with no rubbing.

 

265/70r17s, stock suspension, have wheeled the crap out of it and zero rubbing issues... hand calc with gps based mileage and averaging 18.5mpg and that’s including all of the backroad driving and wheeling... And the truck feels much more controlled to me with the BFG C rated KO2s.

 

I lost 4.5 mpg because of the weight.

 

What tires?

 

Running Cooper Discoverer AT3 in the SL rating stock suspension. They are 41 pound tires. The original Toyo's were 36 pounds. Ride very quiet and comfortable. Can't really say I notice any difference from stock Toyo's other than increased resistance in roll going to an off road tread.
Lost about 1-1/2 mpg. Was averaging 20.5-21 combined. Now getting about 19.5
Seems to have affected me more on the hwy than local.
Not sure the difference in rim weight over the stock Sport rims.

 

Stock to 265 70 17

 

No, what brand/model tires?

 

Stock to bfg ko’s. Also stock alloys to XD rims

 

I went to 265/75/16 e rated bfg ko2s (decently heavy tire) and only lost .5 mpg.

 

Running 265/70r17 falken wildpeak at3 and had to to take off my mud flaps and trim alittle in the front. Have stock off road suspension. Wheel specs are 17x8.5 -10

 

I run 265/70/17 on 4runner TRD Pro wheels. My mpg loss was minimal, if any at all. This probably depends on how I drive as well. When I drive and shift in the lower rpm range I notice better gas mileage, benefit of having a manual!

 

Depending on ply you won't notice much .

Mine were c rated when I had them and it was maybe 1L/100km I lost
