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.
