So I was looking for some new tires for my trailer to raise it up a little and give it a little more durability off road and wouldn't you know it, BFG makes the T/A KO in a hilariously small 195/75r14 size, D rated too!
Now I need some 14 inch rims (from 13) and a move the leaf mounting down an inch or so to clear, I don't need more than .45 inches, since they are only .87 inches taller than my stock size.

I'm inspired now. I should buy two of CrzRsn's many Miata wheels and get some new tires on my trailer too.

I could not love this plan more.

if they are 5 bolt at 4.5 then I want in on that.

Miata's a 4 bolt :/

I'm sorry, but the best excuse for offroad tires on a trailer remains the Rubery-Owen powered trailer (PTO drive). Anything else is just slumming it - 0WD <2WD.

Oh, you fancy.

Which Miata wheels are they that you like?

This should be good.

I could build a powered-axle trailer for my Land Rover with its existing PTO, but the step-down in the transfer case and in the PTO is different - and the PTO is backward. The "easy" thing to do would be to dump the existing PTO box, use a second transfer case, and use another standard axle.
Not like this rig - this *is* fancy. However, it would work in high range as well as low, which this doesn't.

Cheap. 5 to 6 inches wide, 5 bolt at 4.5 inch spacing.

After the lift, the trailer is no longer level and so I was thinking moving the leafs to the lower holes (about an inch) and new tires (another .5 inches) nets me about 1.5 inch lift to level the trailer and get a little more clearance. I thought about an axle flip, but thats just too much lift. The wife would kill me if the kids couldn't get in the trailer without another step.

You know what? I have some of disco axles lying around AND a transfer case from the 109 IIA... hmmm...

That's nice that they gave you two different sets of mounting holes on the frame rail.

There is some dispute as to whether or not its a good idea to use them since it changes the geometry of the axle in relation to the arc of the leafs, but I figure...they put it there for a reason, right?

People do way dumber things with leaf springs. I wouldn't worry too much about it. Just tighten the piss out of those bolts!

Apparently the wheels from some Camrys are 5/114.3 (4.5). I'd imagine Camry steelies would be cheap as hell aus dem junkyard.

It'd be even more tempting for us with a bunch of spare A/early B transfer cases we don't want to put in vehicles due to undersize intermediate gear shaft, BUT when they changed the intermediate gear shaft, they changed (IIRC) high gear ratio as well. No es bueno.

Yeah, that's no good.

The alternative is to just convert the old cases and find some clusters somewhere.
![]() 05/27/2014 at 15:55 |
|
If you're going to go look for clusters you might as well go with a LT230. I'm sure you could find a wrecked D1 for cheap and use it's running gear. Maybe if you have a exra 88 series bed lying around, you can use that as the base.

We do have an 88 bed spare, so have been pondering. The reason to be doing the silly things I described, though, is to match the gearings all the way through so wheel speed is matched. One would either have a trailer t-case that would only work in low range (thus making the high range final drive through t-case ratio difference moot), or one would match IIa car t-case/IIa trailer t-case or II car/II trailer. Pretty sure the LT230/etc. and later style axles aren't a match directly in ratios, so that complicates matters.
I *think* I'm remembering that correctly: low-range the same, high-range different. If not, imagine I said the opposite.

The old style transfer case can be converted to fit the new intermediate, btw: it's just a question of drilling out the hole bigger on the back.

Ah okay, that would make sense then. You are right, the high range ratios are taller in the transfer case:

I had the early Series II/later Series II mixed up: it's different low range between the little shaft t-case and the big shaft t-case, with high range the same. Makes sense, the helical driving the intermediate gear being the same size, the helical driven by it the same size as well. Larger shaft -> larger minimum drive gear size on low range, and swap the corresponding gear/dog clutch on the output. I.e. two gears changed out of necessity on one, instead of three gears changed for the lulz.
In pic: a big-intermediate shaft version. You can see the two pieces that changed, and the two (and size/cutting of third) that didn't.

What's the bolt pattern on your trailer's hubs? I assume its 4-bolt? I'm sure there's plenty of older economy cars that have wheels that would fit, you could probably raid your local junkyard and score something for pretty cheap.

5 bolt at 4.5

Here's a list of pretty much every car with that bolt pattern.
