Size of spare rim on 2009 4x4?

[Bobtube]

Did some routing around online, was trying to find out if the actual rim size of the spare for a 2009 4x4 Ranger was online but can't see anything anywhere.

Am I to assume it's the same size as the 16" rim that comes stock on my truck? Conditions are not great outside right now and don't feel like laying in the wet road to find out for sure.

Currently I'm running 285/75/16 tires and I need to invest in a full size spare. I know I will absolutely not be able to fit that under my truck but I'm looking to see if I can fit that on the rim that's under my truck. Then.... I'll have to move a bunch of shit around as I have a tent mounted in the bed but, we can play with that and make it work.

I can't remember for sure... but I believe my 06 had a 15 inch wheel with compatible sized tire as a spare.

I did a swig out tire carrier to carry a full size spare...

Love that swing arm... Actually everything there looks great. I'm actually thinking I could stand the tire vertically between my tent and the rear window without issue.

Good to know it's a 15" rim. I'm just looking for a cheap option to get a full size spare going without buying a new rim. Aesthetics of a spare wheel don't matter very much to me.

Well don't hold me to yours being a 15.

But I do believe mine was a steel 15 inch wheel. It's long gone now.

Look on Drivers Door Build label for stock tire size, that's what the spare should be

If you are worried about running one smaller tire on a 4WD, don't, running ONE smaller or bigger tire on the front or rear won't matter in 2WD or 4WD
The differentials allows one wheel to spin at a different RPM than the other wheel

You just don't want to run TWO smaller or larger tires, both on the front or rear in 4WD

Thought for sure this was a gaurenteed way to kill your diff? I mean that would be a 30" tire on one side and a 33" on the other. I do go pretty deep into the bush with no reception, so I would be worried about a blow out and then potentially killing my truck on the way out.

Every time you make a right or left turn that happens
Or on a winding road at highway speeds

One wheel on an axle will always spin faster that the other, unless travelling in a straight line
And if 1 tire is 3" less then when going around a corner it would be the same as going straight, lol, on one side

If it caused a problem in a differential then the problem was already there
Its why differentials are OPEN type or Limited Slip type, so one wheel can spin at a different RPM

This is one of those rare occasions that I have to disagree with RonD.

The differential spur gears are intended to occasionally spin on their axis while the vehicle is turning a corner. That is a totally different situation from when you have different size tires and the spur gears are spinning continually while under load. A limited slip differential is even more sensitive to this situation as that will wear out the clutches pretty quickly, ruining the limited slip. The differential gears are not designed for continually having to spin on their axis and that will lead to differential failure. And my belief is that a lot of people who complain that clutch type limited slip axles wear out prematurely have brought that on themselves by having tires inflated differently from side to side, causing the differential clutches to have to slip continuously.

It would be much better to have 2 smaller tires on one axle and 2 larger tires on another axle, as long as one does not try to engage the 4x4 in that situation.

If you have an open rear differential, you can run mismatched tiresfor a short time but you don't want to keep it that way. It's better if the spare matches the rest of the tires.

If you have a limited slip differential, it very much matters that the tires match. In fact, you'll want to make sure you do a 5 tire rotation to keep the wear as even as you can as well. Nothing will burn out a limited slip more than mismatched tires and depending on the vehicle, it can damage the differential.

 

[RonD]

A clutch pack limited slip would wear faster if you keep the spare on for over 1,000 miles
I doubt an OPEN differential would care at double that
(Actually I KNOW that it wouldn't care from my high school days, and always running mismatch tires, lol, and never having a differential issue)

And we were talking about SPARE tires here, lol
My point is, its fine to use a different size tire when you get a flat, on or off road, and like most spare tire use, you get the flat tire fixed and put the spare away until its needed again

I agree if it is kept as a spare. I've seen way to many people run the spare until it's bald before doing anything about why the spare was put into use.

I'm with you here, I've seen lots of people use the spare tire as a "new" tire. My concern lies with being up fairly rough logging roads and running a spare in 4Low.
