2nd gen 265/75/16 fuel economy

Hey tacomaworld!

I am contemplating upgrading tires to 265/75/16 Yokohama geolander at g015. My main concern is a decrease in mpg or km/L as we use here in Kanada.

I don’t do much off-roading, a bit to get me to hikes and such but they are normally just logging roads. My main reason in upgrading is purely to look as cool as all the other Tacoma’s out there.

anyways looking for some feed back on people that upgraded from 265/70/16 to 265/75/16. Did you like the change? Any noticeable loss in mpg or power?

I have a manual 2007 trd off road.

thanks for any help!

 

Going from 70 to 75 doesn't really change the look that much to me. I have the 75's on. Yes, I have noticed a slight difference in power and MPG, but I prefer the happy medium of gaining some ground clearance and not having to trim.

 

Are you taking into account the change in tire diameter in your mpg calculation? If not, it makes your MPGs appear worse than they should.

 

Also consider the weight of the tire different brands can be like 8-10 lbs for the exact same size

 

Going from stock 245/75/16 on my SR5 to 265/75/16, I lost about 1 mpg. I also went to a 10 ply mud terrain. You will probably not lose much going to a mild AT like the Yokohama

 

265-75 should've come stock on the OR. (IMO)

 

I went from a P rated 265/70/16 to a 15 lb heavier E rated 265/75/16 tire. I think it looks better and I can't tell a bit of difference in power. Fuel mileage is exactly the same.

My speedometer was off by 2-3 mph with factory tires compared to my GPS. It is now accurate with the bigger tires.

I see no negatives to making the swap.

e

That is the size Nissan used on their older 4X4 Frontier and Exterra. I never understood why Toyota didn't do the same. 265/75's are more common and less expensive to replace

 

pay close attention to weight, as it can vary quite a bit from tire to tire

im running 16x8 ray 10s (21.5 lb) + 265/75 cooper at3 p-rated (41 lbs) = 62.5 lbs per corner

feels like i lost about 1 mpg, maybe. Tough to tell because now i have a leer DCC + 3/4" drawer system + 1/2" rubber stall mat on top of that which is probably 400 lbs total lol

trucks shifting behavior is acceptable to me. its not constantly hunting gears

 

Not much difference at all as long as you stay with P rated tires. Sounds like you don't need anything more.

 

Its all about weight.

I could put a small skiny 245/75R16 but in a heavy load range E and get less mpgs than a lighter SL or P rated 265/75R16


Do yourself a favor, get a set of SL rated (NON LT load range E) Michelin Defender LTX M/S in a 265/75R16. Mpgs wont take much of a hit at all, and you wont find a tire that grips better in dry, wet, icy/light snow, or a tire that lasts nearly as long or is anywhere close to as quiet.

 

I went from 265/70/17 Hankook ATM’s to 265/70/16 Michelin defenders.

after adjusting for Tire height there might be a 0.5mpg or 1mpg difference on the highway. I imagine that a heavier off-road tire would make a bigger difference.

I won’t go back to an AT tire after my Michelin’s. Big time performance increase on-road, and I really haven’t noticed a difference off-road on the mild out-west Off reading I do. Of course if I’m leaving the pavement it’s because I have a backpack or mountain bike and I specifically want to go where you can’t take ANY vehicle.

 

I put the larger tires, load range E, on mine years ago. I hear lots of folks warning of a loss of MPGs due to the weight. That might be true--I don't know, but I got a consistent 25+ mpg with mine with a 4 banger, 5 speed and conservative driving habits.
