Question: can you put 1 new tire on a car?
Answer: If a car's other tires have lost only 2/32 or up to maybe 4/32 of their original tread depth, it's probably OK to replace just the damaged tire. There can be exceptions, though. ... One way to avoid buying more than one tire is to have the tread on the new one “shaved” so it matches the depth of the others.
