Spare wheel question
 

Hey all,

I have some SCS Ray10s on my 4th Gen with some 285/70 Duratracs, and I'm looking for a cheap spare wheel that would be close in terms of backspacing and sizing so I don't have to do any juggling with mounting the OEM sport spare I have.

The SCS Ray10s I have are:

17x8.5 - BS 4.3" - Offset -10mm

I was looking at these cheap steelies Pro Comp 97 Series Rock Crawler, 17x8 Wheel with 6 on 5.5 Bolt Pattern - Gloss Black - 97-7883 | 4wheelparts.com but their specs aren't the exact same.

They are: 17x8 - BS 4.25" - Offset -6mm

Is that going to make a difference with anything if we're just talking a spare tire situation to get me back to civilization? I'll be mounting a used 32" tire, and I know you want an exact match for a full-time AWD vehicle, but...I don't think an inch will make a difference. The one I have under there now is a very worn and deflated (I have onboard air) 33" BFG All Terrain, but it rubs. I figured getting a used 275/70 is already over 32" anyway, and the duratracs are slightly under 33", so it won't be that drastic.

I have a 255/75-17 Wrangler on a stock Toyota wheel as a spare for my 285/70-17 Nitto's under my V8 T4R. Less than 1/2" difference in diameter, I am not hitting the panhard bar.

Air down the other 3 tires to compensate for the diameter difference when the spare is in use. :cheers:

Clever! What rim are you using for it? I'm hoping that cheap steelie I found is good to go with the dimension being close, but not exactly the same. Just not sure how much a few millimeters difference in offset will make.

I'll expand my search to 255/75's now.

Find yourself a Tacoma alloy (plenty around), steelies use a different lug nut.

Offset would be more to keep a wide tire from hitting suspension components. The 255 skinny (not really a skinny) is narrow enough that a 'narrow' OEM alloy would match up perfect to.. in my opinion..

BTW 255/75-17 is a typical OEM Jeep size tire... :bounce: plenty at the used tire shop, go figure...

The V8s have even less room underneath due to the bigger tow hitch, be aware.

Yep, and I have the towing package. But as noted in the original post, I already have a 285/70r17 BFG All Terrain under there, but it's deflated and very worn. It fits, but it still rubs the panhard juuust ever so slightly.

I'm more interested in making sure the wheel size with the off set and such is going to work.

The joys of having a V8. I can understand the struggle, I have less room in my pants due to a bigger... flashlight.

Should fit I'd think if you use that same worn out 285. I'm sitting on 295/70R17 so no chance for me...lol

Our ...flashlights... are just too damn BIG!

This has all been great information as I just installed SCS SR8 wheels on my V8. I ordered the SCS wheels with new lugnuts provided by them but I have a quick question. For the standard spare that comes with the truck, would I be able to just install is "as-is" or do I need to get a different wheel/tire combo than the standard spare? Totally cool if I have to order a cheap wheel/tire combo to limp me along to get the tire fixed, just want to make sure that I even can do that with the standard spare and it will mount up without issue. Pretty new to this and this thread was super timely! Thanks.

I'm not really sure!

I was thinking I could get that cheap steelie with the good offset and backspacing, but as someone said above the lugs wouldn't work for it or something. But couldn't I just get a set of lugs that would work and keep them in the glove box in case?

If not that, then can I get one of the better backspaced and offset OEM wheels like the 4Runner TRD off-road stock ones? I feel like the only way to make that work would be getting a skinny like a 255/75-17. I think maybe that's what was being suggested, but I'm not clear on that.

As long as the little metal tab goes thru the hub hole you'll be fine, otherwise you'll need another wheel. I'd stick to a worn down 285 to keep the AWD system happy.

Ok, so I can get something like this steelie rim (here) and just get a separate set of lugs that work with it?

I'm probably still going to go down an inch tire size so I can keep it inflated and clear the panhard bar, and then just air down the other three tires to match the size a little closer. 285/70s are usually less than 33" in diameter when measured new, and 275/70 are going to be over 32" by a bit, so the difference shouldn't be huge once aired down a bit. Plus, it's not like this is something I'm going to be driving on more than necessary to get home and get a new matching tire, etc.

But maybe I'm wrong, so I'm open to advice.

Slightly smaller will work in a pinch. If those steelies have a removable cap that can fit the stock metal tab through, they should work.

In an attempt to keep folks wheels bolted on, I assembled various images from the web concerning Lug nut seat types for alloy and steel wheels.

I use ET tuner type lugs for my Method alloys. I carry a set of Toyota alloy wheel lugs for use with my OEM Toyota Alloy spare.

.....and of course check the torque on your lug nuts.
Torque for steel vs. alloy wheel are quite different. :wacko:


:hippie:

You mention that there are different torque values for steel and alloy wheels but you didn't mention those torque values for those that could use that info!
