Will 31s or 32s be too heavy on 2.7 auto 4x4

Hey guys. I have a 2018 taco SR
2.7 auto 4x4 access cab. I’ve decided not to go with 33s as it’s just too much tire for me but I still want to go with 31s or possibly 32s. I will be getting new suspension and leveling kit 3” in front 1” in rear. Also new wheels instead of the OEM, probably the American racing Baja wheels 16”. Do you think I will have a noticeable decrease in power or increase in weight felt when I put on 31s or 32s?
I’d like some photos of you guys with 2.7s that run 31s or 32s as id like to see how it will look.

I’m sure I’ll feel a little something but I want to know what you guys have experienced before I go ahead and make the call. Your input is greatly appreciated, and yes I know it may be a noob question but I am a so called noob when it comes to these trucks especially in a 2.7

 

I run 265/75/16 Cooper AT34S’ on my 2017 SR 2.7 MT 4x4. Didn’t notice a difference in power. I’m not running any lift.

 

you can easily get away with 265/75r16

 

And no need for regearing or anything like that?

 

And you didn’t need to regear? Would it look alright if I lift it too or is there going to be some goofy gap

 

not at all, the weight will not be that different as long as you stay with a SL or P rated tire

 

Slightly slower to accelerate and you’ll probably notice a hit in fuel economy.

Stay with a P metric tire if you’re able to - tire weight is the big killer for 2.7s with the auto trans.

I went from P245 to P265 and lost 20% of my fuel economy with the 2.7 auto. Our trucks weigh about the same (I had a DCSB Prerunner).

 

So you definitely saw a big difference in gas mileage. What about acceleration / holding speed on the freeway

 

Going to 265/75R16 from 245/75R16 isn't that much of a difference. Like someone else said, you'll notice a slight change in acceleration and a bigger change in mpg. Freeway speed is not an issue. I went from 20/24+ mpg to 17/21 and I kept the stock weight vs aftermarket wheels/tires weight the same.

 

run 235, 245, or 255 width and you should be fine

 

Only time it ever sucks was hills.

Elevation made it worse, I had times where I was on the floor with the pedal and still dropping speeds, even under 40 MPH.

 

This.

On my next rig I went with 255s, I’d go that route before a 265 if you have a 2.7 auto on stock gears.

I went with Cooper Discovery ATPs in 255 and loved them, good weight and tread pattern. Still available in P rated which helps a lot with the 2.7.

 

Some good info in here. 2.7 4x4 manual ac myself. A little wider is great and I’ll be looking for a 255 when it’s time just wondering how much taller of a tire can I get in there? Stock sr. Some extra height and clearance to compliment a future lift will be greatly appreciated.

 

255/75/17

There’s a handy tire size calculator @tcBob has here.

 

Same with me. Lift, added armor, converting to 4wd made hardly no difference. Going up a tire size (255/85 Load E) made my truck very sluggish and took my fuel economy from about ~23mpg to about ~17mpg. I regeared to 4.88's and it's still very sluggish with these tires.

 

Does the width have to do much with the regearing? What makes you say stick with the 235-255

 

Much lighter! You only need to regear when the engine is suffering from too much weight, or you want the gearing to provide better torque response. I would never run 285's on my (v6) truck because they actually take away from the engine power because they are significantly heavier...guys do this for looks, but don't actually gain much function. I use to have a 4 banger and 245's were great on it. Many people will differ in their opinion of tires, but skinnier tires perform VERY well. Skinny tires are light, cut through snow well, and steer better on ice. You can get alot of height to of a tire without increasing weight (sometime reducing it) by going .5-1" skinnier and you won't notice difference in performance unless you are going through deep mud.

 

I’d be looking at load range C, that’ll cut a ton of weight.

 

2" lift max before it starts to look weird

 

Good to know. Exactly why I chose 255/75/17. 38lbs per tire vs the 52lbs my Falken AT3's in 265/75/16
