different size tires front and back..
I have an 86 Runner, but at the moment im running 235/75's in the back and 235/70's in the front, neither have much tread left(trying to save up for tires, but still gotta get the bushings replaced and the idler arm rebuilt and an alignment done and god knows what else that breaks after that) i ordered hubs from ebay, since when i got the truck, parts were missing out of both of em, and they should be here tommorrow, but its startin to rain out here and my way to work requires a very windy road that tends to be slippery and the back ends came out quite a couple times already even with very little throttle, so id like to use 4 wheel drive, but i was wondering if i can run those two different sizes in 4 wheel drive in the rain without any future problems? i read this thread https://www.yotatech.com/forums/f116...e-brand-92613/ but im still not quite sure if i can safely run them even with the slightly smaller size difference.. It's only about 5 miles worth of road, but i really dont want to take any chances right now in spinnin out and hittin someone or something, or destroying my drivetrain.. Any help or advice is appreciated, especially if anyone has done this and what problems they did or didnt run into..

that's a little over 3/4" in tire height difference, I wouldn't run it in 4wd if I were you.

with open diffs what does that have to do with size difference between front and rear? I can see left and right but not front and rear. that 3/4" does not sound like that much, but it's a little over a 3% difference. At 30 MPH there will be a 1 MPH difference between front and rear.
with the tire size difference your actually inviting tire slippage in the rear which is what he is worried about to begin with.

Hogdogger. Yes you can fit 31 w/o a lift. And no you dont have to re gear. I just pulled my 31 KM2s of my 87 with a 22re and stock 4.10s. It did fine. Plus 4.88 with 31s is a little too low, your be better off with 4.56s.
Anyway, no more thread jacking. that topic is covered about 100 times on here.

Thanks.. I figured that it wouldnt work, but wanted to double check to see if it was possible somehow without any repercussions or issues before i attempt to try it myself.. And in response to re-re, im getting new tires hopefully in about a month to a month and a half, two at most, got half of what i need saved up, not very much income at the moment, just tryin to get by with what I have and just fixin things as I go along..

here is an easy fix, take your bigger tires and air them down a hair, measure from the bottom of the wheel to the ground, when its the same on all 4 you can use 4wd or dont be cheap and buy two more tires and save yourself a transfer case
