265/65/17 or 265/70/17 for highway tires?

Thank you both for your responses. I really do appreciate it.

1. I am and will be fully stock for the foreseeable future 2021 Tacoma Off-Road
2. (this is more of a question probably) The Michelins I have selected seem to be a good compromise of weight/efficiency/etc. I think? https://bobistheoilguy.com/forums/threads/michelin-xlt-as-vs-defender-ltx-ms.331926/#post-5524863 Basically this tire is just the big box store "version" of the Michelin Defender M/S.


some stats I've collected:

I believe the stock Good Year tires come in at 37 or 38 pounds vs

I could absolutely be wrong here but from what I understand the “big box” ones are just older versions with older compounds. I have had family members use them with great success and in my opinion the old M/S and M/S2 (which I believe the Costco tires are…) are still superior to many newer tires.

 

Michelin LTX's are great. You will get the best MPG possible with those tires. Traction in rain is also good (unlike KO2's). They are fine with dry offroad conditions. Tolerable in snow if you dont have dedicated snow tires.

 

The plan will be to put dedicated Michelin X-Ice tires on the stock 16" wheels for winter time. I've done similar with all my other vehicles and it ends up working well.

 

What transmission do you have, automatic or manual?
My brother has a manual and went with a larger sized tire.
He likes the highway performance better, but his first gear, creeping around the woods is much harder on the clutch (less low end torque)

 

Automatic here.

 

Assuming everything else is the same. Same brand tire, same tread, same load rating, there isn't enough difference in size between those 2 to be able to measure any loss of performance or fuel mileage. Both are the same width. The 265/70's will be about 1" taller when new. But by the time they have 40,000 miles on them they will be the same size as 265/65's were when they were new.

 

Sounds exactly like whit I did. Purchased 265/70 /17 takeoffs from a 4Runner to replace the originals on my 2014 dcsb. The only rubbing was those little baby mudflaps in front on the front tire. Four bolts and it was fixed.
As far as gas mileage I’m still getting around 19mpg without compensating for the difference in revolutions per mile. It kind of messed with the shift points unit nothing major. I unhook the battery in hopes that it relearn and that seemed to help some. Still not quite like stock but close.
