The wheel well is the same across all models, so the wheel+tire will fit. The issue is the cargo tray that sits above the spare tire well. If you can snag one that is for an Onyx, you should be good. Otherwise, you may have to modify the tray to fit a full spare.

 

So I gather the cargo tray for the Onyx spare tire is deeper than the tray for the Touring/XT. Should be possible to locate a cargo tray for the Onyx . . . anyone have experience with this?

 

I purchased an the Onyx/Wilderness cargo tray from my local dealer. It cost about $140.00 and put the full size spare in my 2022 outback touring XT. Works great.

 

Search on YouTube. A few dealer reps have posted the answer to this question. Yes it will work you just need to order a wheel and tire, and then also the insert for the onyx tray that holds the jack.

 

The part number for the foam 'Jack Holder' that will fit in center of the full size spare tire and replace the tray that holds the jack and all the tools for the non-Onyx models is #97035AN00A. Price depends on if one is able to get a dealer discount of not but saw a price of $54.07. This replacement will also hold the jack & tire changing tools.

 

Keep in mind that due to the AWD system you will need to still need to think if this as a temporary fix until you shave down the tire to match. All 4 tires need to have the same tread-wear.

 

I have a full size spare on a matching OME wheel and include it the regular tire rotation when I change the oil

The part # for the onyx jack tray is 97035AN00A.
edit: sorry, I just saw that @tailwind already posted that...

 

You are gonna get your OB dirty like it should be. What made you pick Touring over Onyx?

 

Thanks, guys! Really appreciate all the help. Now I must decide if the full-size spare is worth the cost and whether I want to be bothered with five-tire rotation. ?

Next stop . . . Subaru parts counter and tire dealer. ?

5 tire rotation means you need a TPMS sender in the spare and you need to reprogram the car for the four senders/tires you're actually using. Personally, I'd have a tough time remembering which wheel is which so I'd need both the reader tool to get the S/N and the ODB II tool to reprogram the car.

I have snow tires so I can always use one of those. 6 or 7 years ago, I had a flat in my driveway as I was loading up my car to drive to the airport. I grabbed a snow tire out of the garage instead of using the donut spare for the car so I could drive highway speeds until I replaced tires. I don't take my Outback anywhere more challenging than the ski area parking lot during mud month. I'm fine with the donut.

This thread reminds me that I need to get snow tires off of the cars and the tire shop is probably shut down. My floor jack is at the wrong house along with the torque wrench.

 

Touring interior and leather seats just appealed to both SWMBO and the primary driver. I'll admit the full-size spare in the Onyx made it very attractive!

We picked the brown exterior and the nappa brown leather interior meshed so well it was difficult to resist. ?

The foam 'Jack Holder' arrived yesterday and had bought a full size wheel at Discount Tire and have a slightly used tire so now can convert over to the full size spare tire. The foam jack holder doesn't weigh but a few ounces so it's kind of an expensive piece of foam but I guess it's designed to fit and will keep the jack & tire changing tools from rattling.


Got the Foam 'Jack Holder' yesterday. Discount Tire had a full size 17" wheel for $79, and I had a used 17" tire so now am able to replace the temporary spare tire with the full size tire. The foam 'Jack Holder' from Subaru doesn't weigh but a few ounces so is kind of an expensive piece of foam but it is made to fit and should keep the jack and tools from rattling. Won't have to go through all the commotion of putting the rear tire on the front and then the temporary spare on the rear if I have a flat tire on the front either.

 

Good deal, Tailwind. I'm curious about your 17" wheel. Is it a Subaru wheel or a generic 17" wheel that just happens to fit? I need to go to Discount Tire to see what they offer. My dealer offers Subaru parts at cost so the foam tool holder shouldn't be too expensive from the Subaru parts store.

 

Ralphtt-The spare wheel from Discount Tire was a generic, steel wheel but they also have an aluminum alloy wheel. You can go online to the discount tire website, type in year, make, and model of the car and it will list wheels available for your car. Update-Today I replaced small donut temporary spare tire with a 225-65-17 full size tire on the generic wheel (Stock #49027) I had gotten from Discount Tire. The full size tire fits fine but when I attempted to put the foam 'Jack Holder' in the center of the wheel I found that it didn't fit. The foam Jack Holder is made to fit the 18" wheel, not the 17" wheel. It may take some trimming on the foam piece to make it fit the 17" wheel. An alternative may be just to wrap the jack & tools in a blanket and stuff them in the wheel center.












Apparently the foam Jack Holder fits on the Onyx full size spare tire but it did not fit on the wheel from Discount Tire. Looks like I will be doing some trimming on the foam so that it fits and it does not appear that it will take too much trimming.

 

Got my full size spare tire for my 2020 Limited XT from ebay this morning!

 

Got the foam insert this afternoon, this project is complete!

 

You just gave me an idea, i could use the 18" wheel from our 17 Forester Touring 2.5i (have an extra set after going with Method Racing wheels on it)

 

Gen 5 Outback requires full tire deflation in order to get a full size spare back there.

Spare Tire Question

2016 Outback 3.6 Is there a Subaru aftermarket option for a standard size tire? Also, will it fit in the space where the doughnut is? I don't really mind the doughnut so much but from what I understand , it cannot be used in the front. So this is really unacceptable.

Based on the insert being Onyx specific am I correct in assuming it wouldn't work with my 17" premium wheels?

[/QUOTE

My guess would be no.

 

As I posted previously on a separate topic, I put a full size 17" spare tire mounted on the wheel that Discount Tire specified for the 2020 Outback Premium. It replaces the standard spacer saver doughnut just fine. The only problem is that the foam 'Jack Holder' that comes with the Premium Outbacks will no longer fit. The solution is either to wrap the jack and all the tools in a blanket & throw them in along with the spare tire or buy the foam 'jack holder' made for the Onyx that it is made for the 18" wheel (Premium has 17" wheel). THEN, because the Onyx foam jack holder does not fit the 17" wheel (it's close to fitting) just make it fit by either shaving the foam or hammering on the foam to compress it so that it fits. I choose the hammering on the foam method along with a little forceful pushing of the foam down into the 17" wheel.

 

I also bought a new never used OEM Full Size Wheel and Tire that were taken off from a new Outback Limited identical to my new Outback Limited. I'm having a problem getting a new PN 97035AN00A Jack Holder. I've ordered two but both orders were cancelled by the dealers! I took delivery of my new Outback on the 8th of March, 2020, the day before we were all penned in due to this Coronavirus. I normally live up at 8,000' in the Rocky Mountains but have another home in the SF Bay Area where I'm at now. Net result my total mileage that I've driven my new Outback has been 4 miles. Where fid you guys find the jack holder? Can I reuse the existing wheel hold down screw and is anything else needed? Any other tips or info? Jim

 

I don't have the jack holder, but the full-sized spare you picked up will fit in the well and stay put with the existing bolt. I suppose you can just wrap up the extras and throw them in there for now.

 

My "New" Spare Full Size OEM Tire and Wheel that I bought in Showroom Condition and identically the same as what came on my 2020 Outback Limited, are now installed in my Spare Tire well! Thanks to everyones advice I bought a new PN: 97035AN00A Jack Holder designed for the Onyx and I'm left with a question. Can the rear sliding cover, like with the original Jack Holder, be stored on top of the new Jack Holder under the floor? I had a call and didn't have time to try it!

 

Did you ever get the answer -- I also just ordered the 97035AN00A - wondering if the cargo cover will store in there too now?

 

Yes, the cargo cover still fits underneath.

 

So Discount Tire says I can use a 225/60/17 spare tire for a spare on my Outback limited that is using 225/60/18s does that sound right?

 

I was not sure the smaller size would be a good idea so I went ahead and had them make me a 225/60/18 for the spare, plus the foam tool holder I ordered will fit the 18 tire.

 

225/65/17 is equivalent to a 225/60/18. 225/60/17 is almost an inch shorter and would be fine as a short term spare just like the donut, but it would not be a good choice as a full size spare. While the 17 is a little cheaper, you are correct that the Onyx foam insert is made for the 18 inch wheel. I have the 225/65/17 full size spare with no foam insert to leave room for more tools and other stuff underneath the back floor along with the spare.

 

Yeah I might rethink the foam insert and use the extra space for storage. Thanks for the reply to my question.

 

Well, I am facing a issue with one of my tires, this past monday Mar 8th, I went to get in my car to go to work in the morning and I had a flat tire, it was my rear passenger tire and it had a nail! . So I put the spare tire on (which in the onyx is a full size tire). I then called my subaru dealer and made an appointment to have them take a look at it, to see if it could get fixed, the customer service rep also convinced me to get my 24,000 mile service, since it was almost due. I went there for my appointment on thursday the 11th of March. The performed the 24,000 mile service which includes the oil change and tire rotation etc etc. When checking out the service advisor informed me that they were able to fix the tire as the nail puncture was fixable ( i guess). Today while driving to work i felt like my car was out of alignment, and what i noticed is that my spare tire was rotated to the front and the puncture tired was placed in the spare tire bin and it was flat (again). Definitely coming to see the maintenance manager at my dealer and definitely looking forward to get them to fixed this asap! I know I am on that free tire for life program so i don’t know why the mechanic would have left that brand new full size spare tire on, since it has never been used nor rotated.

 

See this Subaru official TechTips - look at page 15 about Binding on Turns and other issues:

https://static.oemdtc.com/TechTIPS/2016.11NovTechTIPS.pdf

The Techline continues to receive calls from Technicians who have performed all types of unsuccessful repairs to transmissions with a “binding on turns” or “vehicle does not shift properly” concern from the Customer. One of the first questions we will ask is whether or not the tire circumferences have been measured. All too often, the answer is no. It is extremely important when diagnosing this type of transmission concern to make the tires one of the first variables you rule out.

A difference as little as approximately 1/4” in circumference could cause binding and shifting issues due to the ratio imbalance caused by mis-matched tires.

A solid method of measurement is to use a piece of rope and a tape measure. Adjust the tire pressures to specification. Next wrap the rope around the center of the tread and mark it. Repeat on all four tires then measure the difference between marks. Another method is to use a rope style tape measure. A quick keyword search on STIS of “Binding on Turns” will return a list of other bulletins and TIPS articles on this subject.

A 1/4" difference in tire circumference causes turning problems and shifting problems!? Somebody please check my math, but I think that 1/4" difference in circumference works out to something less than 2/32nds in lost tread depth! If that's true, most of us are probably driving around on tires that are too worn to work if we have to mount the donut, or a full size spare not in rotation, or a new tire (without shaving).

Here's my math.

Per Discount Tire, the stock Yokohama Avid GT in 225/60R18 has an overall diameter of 28.7". I understand the donut has the same diameter on the Gen. 6 (just narrower)

A little geometry says that if a tire's diameter is 28.7", its circumference is 90.164" (pi x D). Subtract 1/4" of circumference and the magic number at which your tires won't play nice with an donut/full size spare that hasn't been in rotation (or a new tire) is when they reach 89.914" in circumference.

Working back to diameter, that means if your original tires have worn down from original 28.7" diameter to 28.62" in diameter, you are in trouble. That's a change of just 0.08" in diameter.

How much tread loss do you need to have before you lose 0.08" in diameter? Any loss in tread depth needs to multipled by 2 to figure out impact on diameter. So a loss of 0.04" in tread depth will mean a loss of 0.08" in diameter and 1/4" in circumference.

Tread depth is usually measured in 32nds of an inch. 1/32" = 0.03125". So losing 1/32" of tread is a loss of 0.06250" in diameter and 0.196" in circumference so you are ok. Lose 2/32" of tread depth and you have lost 0.125" in diameter and 0.393" in circumference, which is more than the acceptable 1/4" difference mentioned in the tech bulletin. Mount the donut/full size spare that hasn't been in rotation and you now have turning and shifting problems??? That's shocking to me.

Of immediate concern: I want to get my full size spare which I purchased for my Touring into rotation ASAP! I hadn't planned on doing that because the Touring's TPMS doesn't play nice with five tires, from what I understand.
