i had the exact issue come up. forester, stick shift. i asked the dealership mechanic. he said is a a real problem with tires that have lots of miles on them. we had a catastrophic failure at 1000 miles, so i just moved the spare into place, and put a new one as a spare. (brands were diff). no issues. on high mile tires, i would just change all four since the car is my wife's. i wouldnt want anything to happen. if it were mine, i would try changing just one.
