If a car had lost the tire on one tire and I was to replace the tire with a brand new tire is this the right choice? For example for a front drive car to have one brand new tire and a existing tire on the other side.
Do you

The car will not be damaged by replacing just one of the tires, but there are some less-known things to be aware of. The first is that all tires have some rolling resistance, and that varies between brands and models. Even a matched pair of new tires can, on occasion, have different rolling resistance. That can cause the car to pull to one side when you let go of the steering wheel. If that occurs, switch the tires so the new one and old front one are on the rear.

The other thing to watch for is if your car has anti-lock brakes, it is critical that all four tires have the same outer circumference. Usually the difference between a new tire and others that are worn is not enough to confuse the computer, but if the difference is too great, the computer will detect the speed differences, set a diagnostic fault code, shut the system down, and turn on the yellow "ABS" warning light to tell you. It may be necessary to buy all four new tires, but most cars are forgiving enough that it will not be necessary.
