regear with stock tires?

I searched everywhere in the forum and no one appears to have what I'm looking for. I have a 2012 2.7 prerunner access cab, i have the bfg allterrains on it the stock size wich is the 245s, , my question is what would happen if i regeard to maybe 4.56 or 4.88, will it make the truck faster? i wanna do it for a bit of performance, and i know its gonna affect my gas mileage, it ain't my daily driver. Also, I'm not gonna put bigger rires, I'm gonna keep that size. Not sure if this is the correct place to post this, but btw any help is apreciated

 

If you regear to 4.56 or 4.88 it will make you truck faster from an acceleration point. You also will be turning fairly high rpms on the highway.

 

how high? at 60mph is exactly 2000 rpm, but I like the acceleration part tho

 

Now that question I can't answer. Hopefully someone else will chime in with more knowledge. But yes acceleration will be better.

 

well at least I have one question answered, but the rpms only concern me because I'll be using the freeway to take 230 mile round trip and I do that at least 3 times a year, but besides that if I do the regear I won't have any trouble getting over the mountains anymore, thanx for your response

 

Your probably at 4.10s now, so 4.56 shouldn't be too bad, that's what first gen 4cyl autos got. Lower gears actually won't help much for power at highway speeds. Think about riding a bike going fast in lower gear. You have to work real hard, while when going fast in a high gear you don't have to work as hard

Road RPMs at given speed in miles per hour



10 ....35......70
1 1507 5274 10547
2 823 2882 5763
3 538 1883 3767
4 382 1337 2675
this is what I got with 4.88 and stock tire size, this was of great help, thnx

 

2000 * 4.56/4.10 = 2220

2000 * 4.88/4.11 = 3275

 

does that mean ima do 60mph @ 3275, phuck

 

dyslexic typo 2375

 

I kinda shat bricks on that one, 2375 on 60 mph isn't too bad
, that's the max speed I go on the hwy anyway, I apreciate the help, I'm more inclined on the 4.56 though cause I plan to put a header on it too, and again thanx for the info

 

Just be warned, it's gonna kill your highway mpg

 

yeah I understand, its not my daily driver, I use it on weekends when I offraod, or just to go to the mall wich is like 15 miles away, for my daily driver I use my 95 4cyl ranger, wich does like 25 mpg, I plan to do a build the taco but I wanna start little by little

 

On 33's with 4.56 gearing doing 60 mph im close to 2800-3000 rpm in a standard

 

you guys look at the speedo?! lol - um, i just watch my RPM's
