2.7 MPG with lift

Hey everyone, I have a 1999 tacoma 4 cyl. with stock 29s on it. If I upgrade to 32s and with a 3" will it decrease my mileage that bad? Also what backspacing should I have on my wheels to clear the cailpers. If anyone can help me out there, thanks.

 

My previous truck was a 98 reg cab 4x4 with the 2.7, stock it got around 22. Then I lifted it 3 inches and put 33x12.50s on it, I was pretty easy on it and averaged about 17-18. Never really felt much difference in power either. Drove it like that for 4 years and 100k miles with no issues.

 

Thats not too bad and it'll be a bit better with 32s. Thanks for the help

 

mines a 5 lug but i just recently did 3 inch spindles, stock tires and lost 2.5-3 mpg's (24-25ish to 21.5-22) kinda surprised... i didnt notice any big difference in drag, just very slightly on the freeway.

 

Different truck but my uncle claims he used to get 22 with his 95 p/u with the 4cyl and a 5speed before my cousin put 33x12.5s on it. I think he said he gets 12 now driving highways out in the middle of nowhere

 

I have 33x10.5 and am getting constant 17mpg

 

With consistency I get about 22 mpg, mixed highway/street. Re-geared (4.88), 32" on 2005 TRD Sport wheels, header, CAI. Most thinking people would tell you that the interaction between the skinny pedal and right foot influences mpg most.
