So you wanna put big tires on your 2.7 powered truck

5x114.3 has thousands of wheel options you can go super expensive and JDM something like works or my personal fave sprintheart cpf to anything modern

 

I know this is a 2.7 thread, but I could not find a thread for the 2.4 engines. I have a 5 lug manual trans, and I am planning to lift it. Some people don't like it when we lift 5 lugs, but this is my first car and I don't really have a choice. Anyway, I want to get some AT tires afterward. The tires I want are 245/75/16 (around 30 inches in diameter total) but I would like to know how much they will harm my truck's power output before I buy them. I would still like to use 5th gear and drive the interstate. It will be a daily driver; I will have to drive it to school. There seem to be knowledgeable people on here so I thought I would go ahead and ask.
Also, I'm running 16 x 7 rims. Thank you for your time.

 

Check out the tire size calculator. It lets you compare different sizes and axle ratios.

@hella_tacoma someone here might also be able to answer your question about re-gearing, I think I saw someone asking about 265s a few pages back.

 

Check out this website. If you plug your numbers in, you can compare how new tires/gears will affect your RPMs at a given speed

315s on a 1 inch lift . Grinder and sledgehammer just worked overtime .

 

We have the same feature here at TW already.

This is more for tire size comparisons. The link I posted is helpful if you have regeared or are planning to and you’re curious about how many rpms you’ll be turning at a given speed with larger tires as well

 

The tw link covers regearing too.

 

Hey,

I have a 3rd gen AUTO with the 2.7L, just came across this thread. I'm upgrading my stock steelies to Method 703's which are a few lbs lighter per wheel, but am planning to add 265/70/17 Toyo AT3's which are E rated (I wanted them). They are 49lbs a tire. This thread gave me some hope that my truck will still be usable. I get them mounted in a couple days and after reading online for the last week or so, people made me think my truck wouldn't even move if I put E rated tires on them. I eventually do plan to do some 5100's up front and a Icon AAL in the rear, and that should be the extent of my suspension/wheel modifications.

Anyone else with the 2.7L AUTO have any problems with bigger tires for highway cruising? I know the stock 245/75's sucked and I had to really put the foot down to give it juice on inclines, I suspect that'll be even worse with the bigger tires. I wouldn't mind a soft topper at some point too, but I still should be under payload.

 

I expect you’ll want to regear if you’re going up much in tire size with the 2.7L. It’s a great motor but not particularly powerful and needs rpms to get the job done when pushed.
This tire size tool can help you determine how much things can change. https://www.tacomaworld.com/tirecalc

 

I have a 16 2.7 auto and it’s completely gutless on the highway with 265x70x17 duratracs. Hunts really bad between 4-5 gear.

I’m trying to get more options on 5:29s and a tune or sell the truck.

 

Mine does this stock lol

 

I've got an almost identicle truck (with a softopper), but I have some lighter wheels and P-rated tires in 265/70r17. I want 33's though, my truck has a 2" lift and these tires just don't fill out the wheel well. I have a 9-drive set to 1.9, for a smoother take off, and I always use the ect button. It drives fine, but there's a lot to be desired on hills. I live in the mountains, so my drive to work every day is 2k foot climb. To be honest, the truck works just fine they way it is, but I don't think going up to 33's without a regear would be a good idea. I do floor my truck everywhere haha

 

Top = 285/70r17
Bottom = 265/75r16

This is an excellent tutorial. Mahalo
