Just get 37's and call it a day
Yeap.
37s & 4:10 is even better.
Going up grades in 2nd is 3500rpm @ 60mph & 70 @ 4K. Just did it yesterday.
But wheelin would suck if you don't have Tcase gears.
 
gee if your gonna go big , just swap axles for Rockwells or Unimog Portals and get 53's, get 6:17 gears and be done with it ! ha

i'm not lifting mine, cause I don't "crawl" anymore, just a camping ,fishing, expedition rig and I also am not going for the "Look" or any kind of "compensation" lol .... but eventually with bigger tires, you'll need a regear ... and if you are... definitely 5:29's ... had them in my last yota ...was great !
 
35s are a great tire & fit well.
For wheelin you will still need to regear.
The Tcase gears have a lower reduction than 5:29s...
If you don't ever want to regear anything then stick with 33s.
 
How about at 8,000 ft towing 3,000 lbs?

This is my dilemma. :( Love the look of the 35's on the 80 but feel like I must go 33's if I'm on stock gearing towing our camper in the Sierras.

For me 33's with 4:10 often require 2nd gear down shifts in the 7-8K' Sierras passes. Bugs me all the time but I just keep it at 45-50 in 2nd and it works. 35's may make 2nd gear passes easier as you'd have less rpm to go the speed limit..maybe. Now if we just had a five speed with that in-between gear.
 
35's on stock gears pulling a trailer in the sierras ... ahh no ... I wouldn't you may find your self in 1st gear hoping you make it over the pass...
 
I have a 3fe with stock gears, 35's and live at 7k feet. My truck is well tuned, and bearable around town. On the highway it is painful on anything more than a 3% grade or any headwind. That is with an empty rig. Hence, I have 5.29's waiting to go in. At sea level, it is totally bearable.

FWIW, the truck with 35's is not discernably different than with 33's. I attribute this to wheel weight: (33x10.50 bfg AT's weigh about the same as 35x12.50 BFG AT's on Mickey Thompson Classic 2's). Braking has diminished a little.

I don't think weight of the tire is so much the problem as the diameter is.
 
The key factor that nobody every bothers to mention in their OP when this topic comes up is location and usage. If you live in Florida, Kansas, etc, hell, put some 37's on it!

I live at 6k feet and frequently drive up to 10k feet elevation. Frankly a 1fz with 265 tires (i.e. damn near stock size) is just enough to get by at modern traffic speeds, but I wouldn't go one iota bigger in tire size without added power or gearing.

Opinions on this topic are going to vary wildly depending on who you ask, where they live and how they use the truck.

Pretty sure you won't break 100;)
 

because the taller the tire , makes your gears taller as well , meaning you now have less power to wheel up obstacles, etc., it also means you have crappy performance on the rd and you also put way more stress on everything because of the added height and weight as well !
 
I JUST went through this.... I have 35s and deal with large changes in altitude daily. I have a methed SC, and the rig was still having issues going up the hills. Regeared to 4.88, and now I can do it just fine. Big improvement in driveability around town. Noticeably less stress on the axles. Engine less stressed. The rig simply "feels" better....

Get them and the answer will be crystal clear:grinpimp:

Have them, I wouldn't classify the wheeling experience with stock gears as sucking. The transfer case gears definitely help and are awesome, but not having them didn't make the sable, still ran a ton of stuff in AZ, a few things in Moab, etc.

Actually after putting them in, I miss going 35-40 in low range without the motor screaming at me.
 
Do It!!!!!!

OK north carolina mtns. No SC. 35 BFG MT, 4.88 or 5.29? Slow as Christmas currently with stock gears. Need to pull the trigger and purchase gearing. Advise?
 
5.29 is too low for 35's IMO. Will make highway driving slower and too many revs. The pinion gear is smaller and weaker. 4.88's work well and are still underdriven with 35's. 4.88's are a perfect match to 37's. I've had Nitro 4.88's for a few years with 35's and now 37's. They work great with both tires. If you feel like you needed more gearing after 4.88's then I'd look at tcase gears. High range and low range gears available.
