Yes. If you put TALLER (width does not effect speed, only traction) tires on a vehicle it will increase your potential top speed, if you put SHORTER tires on a vehicle it will have a slower top speed. I say potential because if your vehicle does not have enough power, it will not be able to turn bigger tires at high speed. Also, a taller tire will lower your acceleration in most cases, and a shorter one will increase it, assuming you can maintain traction. Remember to have your speedometer calibrated if you get taller/shorter tires, otherwise it will not be accurate.

Look along the side of the drivers side door for the tire size and load range and speed rating for the size of the tire of the vechicle you want to add the tire to. as long as they are the same size, load range, and speed rating your good to go. if the tire is used try to put the tire on the same side of the car you are installing it on so the tire is turing the same way. Important on belted tires. or go in to or call atire shop they can tel you if the tires will work and if you need to change the rims/wheels. good luck and chech the tire pressure one a month or so
