33's Fitment, and Gearing Question

2550 Views 18 Replies 11 Participants Last post by  hytenor
I have a 03 Reg Cab 4x4 4cyl 5sp. It did not come with 4.10's from the factory, but some 3.something. It did come stock with tiny little tires.

I have already gone to 15x8 AR767 Black Steelies, and 31x10.5's - a Cornfed 3" lift - and put on some fenderflares. The truck looks pretty good.

I want to go 33's. I know I will have to regear - the truck won't even pull my jetski very well with the 31's. According to National Tire, 33's will fit with 3" of lift - but I'd like the have the input of people that have actually done it!

Any idea on what gearing to go with? 4.56?

Thanks for all the information!

Hytenor would be the expert on gearing, he will post here in a minute.lol!
i would go with 4.88's if 33's is as big as i was gonna go.
I've searched around and found my answer on the tire fitment - looks like 3" of lift and 33's do not go together :(

not really, you would want at least 6" of lift for 33's.

I've got 33's and 4.56's with the V6. For you and you 4cyl I'd go 4.88's for sure. I wish I had 4.88's. :(

If you like those fender flairs, I'd get more lift or keep away from 33's. i have 4.5" of lift and have some seriouse issues with rubbing, pinch weld is flat and i now have to start cutting.
make sure you get rims that have 3.75 backspacing, if not then your going to run into rubbing problems. are you taking this truck offroading or just on the streets??. if just the streets then you can run a 3" lift with a 1" body lift and will only rub when your turning is locked. alot of people run a 32x11.5 tire with a 3" lift kit only and it looks nice and keeps you from having to regear etc.. :cool:

Do you have the auto or the 5spd tranny?

An '03 4x4 with tires smaller than 265/70s??? dang, that's the first I've heard of that. What size tires do you have?

the "03 4x4 2.7 5-sp should come with 265/70/16s and 4.30 gears.

you can run 33x10.50/15s with only 3" of lift with no problems. the closest equivalent 16" tires will be the 285/75/16s which are 33x11.4s and 3" will "clear" them but you'll still rub some. what backspacing do you have on your AR767s?

I run 33x10.50 BFGs on stock 7s and 4.88 gears

the "03 4x4 2.7 5-sp should come with 265/70/16s and 4.30 gears.

I've got a 5spd. ....Steve
Thanks for the input guys, I offroad at best 6 weekends a year. As far as what my 03 4x4 reg cab 5speed *should* come with -- I actually just pulled out the window sticker to confirm. It came with 225/75/15's, I just re-visited the gearing code, it's 3.91. It was a bottom line truck with the only options being A/C, and 4x4.

Looks like to get up to 33's is just cost prohibitive -- getting to 6" of lift, and the gearing alone would be 3Grand or better.

I guess I better just like it the way it is! :)

holy crap batman! and here I thought Toyota stopped putting out 4x4 trucks with the dinky tires, sheesh. I know the early, gen I rigs came that way but not the new ones....learn somethin' new everyday. I wonder if this is just a quirk with the reg cabs...

with 3.91s, a 29" tire (235) will be about it and maintain decent power.
i went from 31x10.5s to 33x12.5 with kings (2.5") and it rubbed... BAD... i only had it like that for a little while before i got long travel, and i wouldnt recommend it, especially if you want your truck to see dirt. also, i regeared to 4.88 from 3.58s, MUCH better. id definately recommend 4.88s, but i wouldnt go any lower.
Ive got 4.56 gears w/ 33x12.5 bfg muds and I have no complaints power wise (5 spd, 4 cyl)
what about v6 with 4.56's with 32x11.5x16 I guess thats about 275/70/16 I think. anyboby have this combo, work, not work?

with the v6 its a waste of $ to regear for 32s, IMO unless you have the AT and tow/haul a lot. 4.56s/33s and the v6 are great for the 5-sp or the AT. With the AT you can go to 4.88s/33s if you want more low-end and don't mind slightly higher hwy rpms. either will help gas mileage as well.

265/75/16s are the 32x10.50s. A 275/70/16 would be approximately 32.2 x 10.8". does anyone make that size?
I ask because I am about to convert from prerunner to 4x, and the diff I found already has 4.56's in it, for a good price, so I can just swap in the 4.56's in the rear to match. just wondering cause every other diff that I have come across so far had 4.10's and cost much much more than the one I allready found

with the AT it won't be too bad but you'll run much higher rpms at speed on the hwy. off the line will be great ;) figure around 2800 at 70 with the manual and around 2350 @ 70 with the AT, not too bad but about a 300 rpm difference from stock
