Hi,

Concerning the new HZJ models (71,76 and 78). As an option it is possible to carry the spare wheel on the rear door. For instance, this is necessary if you have the secondary sub tank in the HZJ78.

But mounting a heavy wheel on the rear door puts a lot of extra stress on the hinges. How do the hinges cope with this extra load? Will the door tilt after a few years and closing/opening becomes difficult? What's your experience?

I'd look into in. In my experience with toyota and this sort of thing is if its on it, its often braced for it. I haven't taken a close look at your model so I cannot say but I do know that on a 61 with the optional tire swing out that it is not merely bolted onto the body but it braced from inside the rear quarter where you cannot see it unless you cut it open. So, if your HJ61 didn't have it to begin with then you can't have it at all without some reenforcement.

In oz all VDJ76 have the spare on the rear door, for troopies I think it is optinal depending on the fuel tanks. My BJ74 has had the spare on the door since 1986, works fine.

Is your rig holding a 35" spare on the back mate
 
yep and i mount 36" tractor tires to it.
no issues till you back into a tree, then FAWK, then 'football' tech to get it back out.
 
I hang 33's on my 78, been that way for about 4 years plus time spent in the hands of the previous owner(1992). Just the other day I finally adjusted the door up because of a little sag +- 5mm, causing the door to ride up on the catch and bind slightly sometimes. I slipped one washer on each bolt (3) between the body and the bottom hinge. This lifted the door back to its smooth operation.

Yeah I carry 35''s on it, to fit my new 35'' simex I had to redrill the holes to move the carry towards the outside of the car, otherwise the small door wouldnt open.
 
Here in East Africa we routinely take them off the door as soon as possible and put on tire carriers. Most people here think one year is too long for a tire to hang on the door. However, I think the main culprit of sagging doors is not so much the tires but the tires + extremely rough roads at higher speeds.

hint, 35" and bigger flip the tire mount upside down.

Doesnt work on aus spec, only changes the angle the tyre sits at, it actually made mine worse and hit the rear bar area/bottom of door. I needed to move it away from the centreline of the vehicle.
 
I have my 35" spare on the back door on my 74 - no problems. If you look at the top inside of the door there is a catch from the roof that provides outboard support for the door. By repositioning the studs I have the spare tire rest on the back bumper so when the truck comes down hard the tire is cushioned on the bumper. When closing the door, the edge of the tire must deform slightly, but the tire is very firmly supported. I tried flipping the spare tire rack last time, but did not work for me. I made a 1" spacer, with longer studs so the 315 clears my back wiper now.
 
I flipped my wheel carrier around and it still hits my wiper arm. 255/85r16 spare and my rear door and it squeaks and groan's like crazy. It doesn't have an easy life. lj78 lwb:meh:. If I had a choice rear bumper swing out. Wayne built a beauty.

Take care
 
I have had my tire on the door mount for 6 years and whilst I had to adjust it when I first got the truck I haven't had to adjust it again since. If you look at the design of the latch the 'bar' part, that the latch catches around, goes into a recess and so the weight is supported in the closed position. I believe that the reason the doors sag is because of badly adjusted doors that don't close fully and so the weight of the door isn't taken fully when closed. If your door rattles (normally because of the rubber 'cushion' being missing or not adjusted to close properly) then you will probably find your door will sag.

Even with 33s the "flip the tire carrier" made the tire block the small door on my BJ70. Plus it blocked the wiper arm and, to my eye, looked "off."

I remounted the tire carrier in the normal position and repositioned the studs- 2mm clearance for the door and back to that jaunty angle.

That said, a tire carrier would be a dream.
 
crap, you are right, i flipped it and moved it over ...
my bad, sorry guys.
 
If you are driving on corrugated roads at speed the answer is NO.

Use a rear wheel carrier - otherwise the door may fall off at 80km/h....

I use 285/75R16 and they were definitely too heavy for my door (HZJ78 General Spec).

Look at something like the stuff from Kaymar - or get it made up yourself.

Cheers

interesting, sounds like a story behind the "otherwise the door may fall off at 80km/h" statement. care to share it?
 
Ferret offroad in perth WA make a light braket which spaces the carrier out so you can fit a larger spare.
