My 2015 Subaru Outback got a flat tire

6. Total BS Unless the Tires are Being Recalled as Defective.

If you only have 4000 miles on the tire and tread depth is sufficient (which it should be unless it is way out of alignment or the tires are run with too little or too much air), then there is absolutely no reason to replace your three good tires. In fact, it is waste of your money and natural resources. Many of the tires that are replaced are not properly managed and end up in piles in some rural location (where they occasionally catch fire (worked for an environmental agency for over 30 years and saw this frequently).

Assuming it was a nail or something sharp that punctured the tread, then it is relative easy to fix a tire (sidewall damage is not repairable). You can buy a repair kit for around $5.00 where it only requires that you widen the hole and then insert a plug and pull it out quickly (rubber cement on a rubber strip). It is very quick and painless to do anywhere safe. An inexpensive portable air compressor will do the job to refill the tire too (nice to have in case you have a low tire as well).
