Fuel mileage

Putting on bigger tires makes the odometer under report miles right? Meaning the calculated mpg is also less than actual?

 

I was thinking the same thing, cruise works great in my truck.

 

XL.

 

399 miles
18.52 Gallons
21.54 MPG
Dash display - 21.5

 

Bumping this up instead of creating another thread.

Originally I was at 17 city 21 hwy with stock 245/75 dunlop tires.

Topper and 265/70 cooper rugged trek and now
I'm getting 14 city.

Does that sound about right?

 

That’s not great, if you went 265 70 16 and std load that’s only a 41lb tire. Did you go 17 inch and E load for 52lbs?

 

41lb tire

 

I drive 75 mi a day for my commute. 70 of them are highway. I use cruise control at 70mph Toyota speed which is 68 on waze.
If I see braking coming I disable cruise and coast. I've had the truck 2 weeks, v6 auto. It's kicking my old manual 4 banger's mpg.

 

I have a 2017 Tacoma TRD Off-road short bed and my current setup is:

1. Wheel setup: Black Rhino Chamber 16x8 -10 offset on 285/75/16 BFG KM3
2. Manual Transmission
3. 4.88 Nitro Gear
4. Lifted about 2 inches
5. Magnuson Supercharger with an 87mm pulley
6. Yotawerx Tune
7. No armor and now additional added weight to the truck

I live in Las Vegas, and my commute is around 20 miles going from the west side of town to the east side with a steady 1500ft elevation drop which most of that drive is on freeway.

My fuel efficiency before adding the supercharger setup on that drive was ~19-20mpg going west to east. The return trip going east to west was typically around ~16-17mpg.

After the addition of the supercharger that same trip I now average ~16-18 mpg going west to east. The return trip going east to west is now around ~14-15mpg. Regular street driving around town I only get around 12-13mpg but my data my be skewed by having a heavy foot now that the car is boosted. Hope this helps.

 

Sounds like a sweet rig!

 

Maybe I need to go fill up my tank and go for a actual ride, instead of all the stop and go traffic crap.

 

I'm stock in my TRD sport. I get 24-25 mpg highway if I stay under 70 mph (highways around here are 55 mph or 65 mph anyways). City I get about 17-18 mpg. I typically average the advertised sticker mpg of 20 mpgs (around 21 mpg average in summer, around 19 mpg average in winter).

 

That's is, I'm getting different tires.

Michelin defender ltx m/s sound about right.

 

Highly likely it was something else, Premium fuel contains less energy than Regular per unit.

 

Filled the tank and got out of the city, still a few stops here and there but mostly 45mph.

 

I do however, I don’t drive 75+ on the highway. Rural area, two lane roads with speed limits at 55-60. Rarely drive over 68

 

22 is normal I average 21-23 doing 70 mph . Worse when going 80mph . It’s a truck not the most fuel efficient vehicle .

 

Very true……it’s a lot better than my old 97 F150 with a 5.8L

 

Yeah, my 1995 F-150 with the venerable 4.9 straight six and a 5-Speed manual rarely got better than 19 mpg, but given it had two gas tanks, it could go a long damn way between gas station stops.

 

I had an old ‘70s Ford with duel tanks. It was all fun and games until it was time to fill both tanks back up.
