I purchased a new 2017 Outback 2.5 AWD. I just found out that if one tire needs replacement all must be replaced. I don’t like this. I had 2 tires replace once on my old Honda, but no requirement for all 4. What can I do about this???
Almost nothing . A good tire store will measure the tread and tell you if a new one will work or not. The damage cost of ruining the all wheel drive is a lot more that the price of tires.
Sorry, but if you want all wheel drive traction in your Subaru, that is the price you pay. You must rotate tires regularly, every oil change for example and replace all 4 at the same time. Tires are cheaper than the all-wheel-drive driveline components (a LOT cheaper!!)
