Changing axle gears?

I have been searching for a while and I have not really found any good answers.

I am looking to get a 2010 or 2011 Tacoma dbl cab 2wd (possibly Prerunner) for the wife. We have already discussed that she wants bigger tires. She wants the bigger more aggressive looking stance but I know this will kill the mileage. Has anybody done the bigger tires and gear swap to keep the truck in a more normal power band to keep mileage?

 

The 6 cylinders have 3.73 gears which work fine for 31, 32 or 33s. You can gain back some power by regearing. But don't expect to regain all the mileage because bigger tires just weigh more even if you regear you are still spinning more weight.

What size tires you looking to get?

i realize that all trucks are different, but i get 18.x mpgs(see the fuelly badge below!) w/ 5" lift and 33s. i know i am a rare occurrence, but the 3.73 gears are just fine for 33s as stated.

 

thats exactly what i am going to do next...along w/ a truetrac!! but the truck w/ 33s and 3.73s would be just fine for his wife...

 

Tch a supercharger will fix that

 

Thanks for the replies so far!!
I was thinking 33's. It will be a V6 and Auto for sure.

If I can do anything to keep it at least 18mpg I would not complain at all.
