I have 2010 ranger 4x4 with 3" body lift on 30's. I want to go 33 soon and was wondering what the fuel cost diffrence is. I do an hour hwy driving 4 times a week. And its hilly being Nova Scotia. I did a search and couldnt find anything on it. Also does the width make much diffrence.ie between 10.5 and 12.5 . Any info would help or if theres already a thread on it just point me in that direction. thanks

these are the tires i might be buying, not sure yet but either way i want 33's.

You'll loose a few mpg but just get a tuner and set your tire specs

 

I didn't really notice a difference at all when I went from 31s to 33s. I drive all highway though and it isn't really hilly around here.

 

The width is what is going to mess your mileage up because they will produce more wind drag running down the road, and there is weight difference between a 30" and a 33" tire too. I've never been to Nova Scotia, but if it is hilly like you are saying, I would expect to see like a 1MPG drop. But I could be wrong.

But that being said, I would go ahead with 33x12.50 just b/c they look the best with a BL lifted truck IMO.

 

ok.thanks guys. thats good news. im fine with a few mpg loss. will the tuner help with a standard? I should have mentioned its a standard with 3.73 gears. might be interesting on the steeper hills but it seams like alot of ppl on here are running 33s on 3.73 so im not too worried there.

 

Do you have a 4.0 or 3.0 engine? 5spd or Auto? If you have a 4.0 and auto or manual you will be ok. Just your out of the whole and towing maybe a little more sluggish than what you are used to now.

If you have a 3.0 you might want to regear to 4.10 or 4.56 just because of the extra stress being put on the tranny.

 

I have a tuner on my truck. It is a Xcal 3 with custom tunes. My truck is a 4.0 Auto, and the tuner helped a lot especially in the shift point areas. In Tennessee, we have a lot of hills and I pull a trailer almost everyday. Hard and quick shifts will make an auto trans last much longer. But if you have a 5spd a tuner will help too because you can recalibrate your speedometer (after adding bigger tires) and it will give you some more power. A lot more power compared to any bolt on engine accessory you can put on.

 

No 3.0s after like 2007-2008 Matt

 

^lol my bad. Brain fart.

 

oh, man. you are going to want to re-gear asap. anything over 31s need at least a 4.10 ratio. even 4.56 would be better suited. if you keep 3.73s, you will barley use 5th and maybe even 4th. your rms will be too low for the powerband of the motor.

 

with 373s you'll prob lose 3 or more mpg. i lost 2 with 4.10s but i really don't care about mpg....i drive a 5.8L now lol

as far as width goes, get a 15x8 or 10 wheel and get 12.5" wide tires. 10.5= pizza cutter status

 

thanks for the help. it is a 4L 5spd. i will eventually be changing it too atleast 4.10 but its not in the budget right now. want to put lockers in at the same time so have some money to save first. I agree about the pizza cutter status,dont want that.lol. im going to start looking into tuners. sounds like a good idea.

 

Iv gotta agree wit heveryone lol. The bigger the better and you will lose a little just because of wind resistance. Higher up you are = more drag. But honestly, who cares about mpg when your truck looks amazing!!!

 

i noticed quite a drop going from 31's to 33's with the stock 4.10 gears but after re-gearing, headers, exhaust and good custom tunes for my X-Cal i can now squeeze out stock or better than stock mileage if im easy on the skinny pedal. btw, i saw no mileage difference going from 33x10.5 AT's to 33x12.5 MT's.

 

I just drove 50 miles today with my 33's and a tuner. Average speed was 73mph and my average MPG was 21mpg.

 

I have no clue what my mpg is...and i really dont wanna know lol

 

I do 400 miles of highway driving a week @ about 70 mph with 3.73, the older 4.0L OHV and 33x10.5 tires. Economy is as low as 14.2 if don't care, and and all time high was 16.2 miles per gallon when I really pay attention.

Course, my truck is pretty tall, has 200+ lbs of steel/bumper/winch hanging off the nose, and at least another 200lbs of extra weight due to rock sliders and aftermarket lift kit parts.

I wouldn't be surprised if a slightly lifted truck with the newer SOHC, 3.73's, and 33x10.5's got around low 15's to mid 17's in terms of fuel mileage (such as your truck).

Width of the tire will also make a big difference, 10.5's contact patch is smaller, tire is lighter, and less backspacing all helps elevate potential mileage numbers. Whereas 12.5s have a pretty big contact patch, are heavier, and more backspacing to set the tires out farther from the body. Expect around 14-17 with 33x12.5's.

I chose 33x10.5 for 5 reasons:
I like the look of a skinny tire
Very good traction in mud, ice and rock
Better fuel economy
Less wear and tear on drivetrain due to lighter tire weight
Skinny tires = a narrower track width due to wheel backspacing (means I can get in some really tight trails )

 

Ive decided ill buy a superchip before I buy the tires. That way I can adjust my speedometer for the tires also. I do agree that 10.5 should burn less fuel but i like the look of the thicker 12.5 alot more. looks more aggressive.

 

What about a 32x11.5??

 

I've got 33"s and 3:73's and I still use 5th gear on the highways... 110km/h on the highway is around 2300rpm and I get around 400-410km to a tank. Its a bit slower getting up to speed but it still gets me around. A re-gear would definitely help if you can afford it but you can manage in the meantime.

 

I'm getting between 14/15mpg usually 420kms to a tank. I could go further, I'm sure but I never want to run it completely dry:P I was running 373's with the 33's for a couple years then switched to 410's. I nice change to overall driving and not much to fuel economy.
