I had a tire go out on my 2012 outback last night... something in the road slit the interior sidewall. Long story short I need a new tire.
My car has about 16k miles on it, and these are the original tires. I've read there are problems with alignment on these due to the awd so im curious if i should just get a tire at the local discount place or do it at a dealer.
Alignment isn't the problem. Different sized tires (or worn ones) cause the wheels to rotate at slightly different RPMs, (smaller diameter=more RPM) which stresses the differentials. And breaks them. You'll want to keep the tires close in size and wear. See your owner's manual if you want it from Suby, it's in there somewhere.
Also, with 15k on the original tires do I need to get a pair or will one suffice, and if so whats a good but fairly affordable tire for these things?
Getting a pair of tires after 15k miles would be a bad idea, for the reason above. The tires people would recommend would be very dependent on your
driving habits and needs. For example:
1. On road, never off road? Occasional off-road? Never off-road?
2. Drive in cold weather? Snow?
3. Is performance or mileage more important?
Called the dealer this morning but their service department is out til monday due to the holiday weekend, so thought id research before hitting the local walmart or whatever.
The other option is finding a local shop that can shave a tire down to the size of the other three good ones, then you can just get one. Tire Rack (online) can do the same, IIRC.
I lost one tire, similar situation. I replaced all 4.
