9 MPG

With synthetic 75w-85 in the rear end, stock tires, no lift, a tonneau cover, and brakes that aren't sticking, it shouldn't go much below 13 in town. Even here with a 5 mile commute on winter gas in snowstorms it still stays above 12.

 

Touch your wheels after driving and see if it is really hot. I think the rear parking brakes can stick if the lever is rusty. You'll probably be able to smell it burning if it is that bad. I just noticed this with mine and I'm not sure what to do yet. My rear wheels get way hotter than my front wheels which doesn't seem normal to me.

 

tell me more

 

285/75 comes out to about 34.8"/11" in tires.

 

I’m a fan of skinnies. I have fat 35s and I hate ‘em. I have 315/70/17 and they are just too big for my taste. Kickin’ around the idea of 255/80/17 skinny 33s.

 

It's the perfect size if you spend any substantial amount of time off pavement. All the sidewall of a 35 (just a hair more in reality), but narrow enough to keep your tight turn radius, and it won't take as big a hit on mpg.

 

I drop 3 mpg when I went from 255/70 to 275/70…I’m thinking about changing rim and tires too…lol

 

I still have my stock set. Those are on 275s I think.

 

I need that patch bro

 

Try it out and see, how much it’ll help

 

No. I really only put 87

 

I appreciate the advice. My biggest problem with selling it is I have the truck fully paid off. I just pay for gas and insurance. I originally bought it for 26k (which was a pretty good deal) back before gas prices went crazy and started working 50 hour weeks while in high school to get it paid off. It’s a hard decision because I worked so hard for it and it would legitimately hurt me seeing it drive away with someone else. I might just buy a motorcycle or something for everyday use.

 

sounds great! i ended up with the tires i have because my buddy sold me a set of 5 alpha equipt echoes with basically new toyo OC 315/70/17s for $1000. it was a deal I couldn't pass up, especially because i needed new tires anyway and really wanted 17s over my stock 18s. win win win. i have ST maxx 255/80/17 on my 4runner and love 'em. Thought I'd go with the same on my Tundra because skinny 34s don't really exist... do they?

 

They do. 285/75R17

 

aw goddam it

 

14.4 MPG on 612 mile trip with U-Haul 5x8 and Crewmax bed full of heavy things covered with a tonneau. Mostly flat the entire way. Stayed close to speed limit the whole trip.

 

I have a 2011 crew max with a 5.7 L just went on vacation 2000 miles round-trip average 17 miles per gallon stock tires in this

 

i get 23mpg on 35s, don't know what all you guys are doing wrong

 

One thing to keep in mind is that traffic in SoCal is on a different level from "traffic" in other parts of the country. Cruising to work at 40mph vs stop and go rush hour traffic for 2 hours a day will make a huge difference in mpg.

 

socal here and on 35's. around 13 mpg but I drive at 70 mph most of the time and no abrupt acceleration unless it's getting on the freeway.
I also have a camper shell. Might help with wind drag vs open bed.

 

I was getting terribly-crappy-mpg when I got 35s. Re-geared to 4:88 and I'm pretty much back to just the crappy-mpg range at approx 14 mpg hwy. Although I didn't see a huge benefit right away as it took time for the computer to adjust, probably after 3k miles or so, which for me is like 6-8 months lol.

And speaking of S.D., I have to drive out there tomorrow (from Temecula) so that should be a whole lot of fun!
