so right now with stock 235 75r 15's(36lbs) my truck does fine, I want to know if I upgrade to 32's(47lbs), will it be a dramatic difference? And some specs on the truck:2000, 4.0, automatic, 4x4.

 

it shouldnt be to bad. i was running 31s and 3.73s. hell i was running 31s and 3.27s

 

Thats about what I have with the 3.slow and I dont mind it. I do have a 5 speed, I went from 2700 rpm cruising to 2100 rpm cruising at 65 mph. I'm getting 26 mpg on the freeway instead of 23.

Yeah, hills and passing require 4th or maybe 3rd gear, but I think you will have no issue with more power and an autotragic.

 

youll be fine

 

It's alright, even with the 3.0, I think you'll live.

 

LOL you fail! He's got a 4.0


I've ran 3.73's and 265/75/16's (metric 32's) for 2 years in my truck without any issues. Mind you I do have a manual tranny, so that makes a difference. It will be a change, and its just something I have lived with.

 

i have 32s with 3.55s with my 4.0. works fine for me

 

So these tires wont be hard on the tranny?

 

damn i would die

 

no it wont be to hard on the tranny.

and i love my 3.55s and 32s. i get amazing highway mileage, although my city mileage does suck. i tow a 5,000 lb boat with it too and it pulls fine

 

wow i had 31s and 3.27s and it sucked ***. now im running 3.73s and 30s and its nice to have some power

 

did you have a 4.0? i mean ideally id like to get 4.10s, but i drive from Santa Cruz to Orange County (about 400miles) a lot so im gonna stick with these gears for now. plus I have no money. haha

 

yea i have a 4.0

 

I was talking about my 3.0, his 4.0 would be better off.

 

Should be fine. I had around a 31 inch tire on my 4.0 with 3.73s for a year and it was good, until i lifted it 35's w/ 4.88 yukons.

 

How about with a 3.0 with 3.73's?

 

It's not bad around town, but if you do any driving above ~70, overdrive (or 5th gear) won't hold well on inclines. Lot's of downshifting. That's why I switched to 4.56s.
