Default Newb flat tire question

Hay all. Of course I can't find my Owner's Manual when I need it. And - - I did a search on here, but no luck (I know to at least search before asking - so don't growl at me if it is on here and I fail at searching!)

I have a flat on my Outback. The flat is on a front wheel. Does it make a difference which wheel has the donut? Like, should I move a tire from the rear to the front and put the donut on the back? I know it'll be a logistical nightmare to do that ~ ~ but less of a nightmare than damaging the transmission/differential, right?

Thanks in advance for any help. I'm not planning on tackling this until the morning, so. . . .

P. S. - I do have Roadside Assistance with the warranty and my Subaru extended service contract, but I'm not a fan of calling them for something I can do myself.

I dont know about the donut, but I have been told a couple different things from different people about replacing the tire. First I heard from my teacher at tstc, You have to replace all four tires or else you will work the transfer case and or differential with awd, then after some posting here someone said in the owners manual it states the tires have to be within 2/32'nds or something of each other when you replace a tire. So you cant just buy a new tire and put it on there is what I took from all of that. Id find your owners manual or call subaru before you end up buying a new tire. As for my two cents on the donut, completely guessing here, If your were out on the road in the desert or in the freezing cold I dont think subaru would have you moving the donut to the rear tire and moving the rear tire to the right front just for a flat. I dont know if you've ever rotated your tires before but the drive tires switch so the right front and right rear switch and not the other way around like on a fwd or rwd. If thats at all confusing, go find your owners manual .

if anything put the spare on the back. 70% of ur braking is with ur front tires. plus u turn with ur front tires as well. better grip with a real tire and not a donut. thats what i would do

Thanks - -- I'll either put it on the back or just stop being bull-headed and call Roadside for some help. I figure they should know what they are doing?

I appreciate the quick help! Oh, and e[tx] - yeah, I remember reading something about them having to be close in tread depth, same tread pattern, etc. I just bought all four of these about a month and a 1/2 ago, less than 1K miles, so I should be good on that. There is a nail the size of a spike in it, but since it's not on the sidewall, I'm hoping they can plug it.

But - - I think I'll also dig around a bit for the Owners Manual = =shoulda just kept it in the car!

Thanks again!

the spare is the same diameter as the OEM tires, so you aren't going to damage the diffs or anything. However, I would agree that putting it on the back would be preferable for handling and braking. Also, if your outback is an auto you are "supposed" to pull the fuse and disable AWD, atleast thats the protocol in the manual.

I'd think twice about this. I agree about the braking, but I know with my LGT, I have a rear LSD. In case there's any diameter difference in the donut, I'd rather have it on the front, since the front diff is open. I don't know what they do with the outback turbo version......

I had a nail in my tire and it was way close to the sidewall, I wouldnt of gotten it plugged anyway. I drive my car a bit faster than I think I would drive an outback, especially around turns. I didnt want a plugged tire to go boom when I was pullin some g'eez. I ended up buying four new ones and now have 3 spares for if it happens again, I would just have to get the tread depth matched on the new one going on. It was an expensive frickin nail, thats for sure.

You will be able to drive home on your donut in the front fine. Just take it nice and easy and try to replace it asap. Make sure to try to replace it with the same tire of nearly identical tread.

Well, get this. I found my Owner's Manual and I found my extended service agreement. I have the Subaru Gold Plus coverage? While I'm still under the Subaru 3 year/36000 mile warranty, I have a $300 coverage for road hazard tire damage. Guess I'm calling for roadside and I'll call my dealer about how to get the tire replaced. I feel a lot better about that considering they are new tires. I'll let roadside handle the donut issue. I would hope they know what they are doing. But - I'll keep an eye on them based on what you have told me on here.

Thanks again for all of the help. Not happy about the flat, but relieved I won't have to pay for a replacement tire. If the dealer needs to order the tire, I'll be careful k04sti. I appreciate the safety advise.

i was told to only put the spare on the back because it could mess up your differential. but if you are stranded with only one jack, that makes it a little difficult.

If you have a rear LSD, the donut should go on the front only. You can do it with one jack if the flat is in the rear. Just swap one of the fronts for the donut, than swap the front for the flat. Or if you want to make life easier, just get a full-size spare ...
