Let's say the vehicle is FWD, and the right-front tire needs replacement due to an encounter with a pothole. The remaining three tires have about 5/32" remaining, maybe a bit less.
Should you replace 1 tire (just the affected one, and of course it would be the same brand/model) or should you purchase two?
