2.7 liter Fuel Mileage with bigger tires

Hey, I just bought a 2008 Tacoma, 2.7, 4wd 5 speed. I'm enjoying the gas mileage, almost 22mpg, but I'm wanting to put a 3 inch lift and run 285/75/16s. I'm just curious as to what to expect my mileage to be with the larger tires.

 

Not sure. Maybe around 18-19?

What's with your screenname?

 

That's my configuration. I never got 22. 18mpg was my stock starting point. Do you drive downwind with a tailwind?

I'm running 285/70R17 Goodyear MTR/Kevlars.

Immediately after I put on the suspension and tires, I was aggressive with the skinny pedal and my mileage dropped to 14. Now I'm back to more conservative driving and I run around 16.

I drive an urban area 18 mile (each way) commute with a lot of stop-and-go.

As they say Your Mileage May Vary, but big heavy offroad tires are hard to get rolling (stop and go mileage takes a hit) and have more rolling resistance and wind resistance (highway mileage takes a hit.)

 

its going to go down quite a bit, id say around 16. when i had 245/75r16s i was getting around 23.5-24mpg consistently and just going to a wider tire, 265/65r17, its basically the same height just a tad taller, i lost about 1mpg just from that.

 

Not much city driving. I drive mostly on the highway to and from work. I was impressed to see 22 mpg. Well thanks for the info!
