Plus sizing wheels and tires is a popular trend among car enthusiasts. Adding inches to the wheel diameter for wider, low aspect ratio tires can increase your car’s performance capabilities including handling and stability. Some people will also plus size for the appearance; they may like the way a larger wheel and tire package fill up the wheel well of the car.
In simplest terms, plus sizing is when you increase the size of your tires and/or wheels from the original size put on the vehicle when manufactured (also known as the Original Equipment size, or OE). Something that was usually done after the vehicle was initially purchased, it is now common for auto dealerships to offer wheel and tire upgrades at the time of purchase.
If the wheel diameter remains the same and only the width is increased it is called “Plus Zero.”
If the wheel size is increased by one inch it is “Plus One.” This sizing mounts tires with an increased section width and a lower aspect ratio on wheels of a larger diameter. A Plus One fitment for a car with 16-inch original equipment wheels would use 17-inch wheels. As a general rule of thumb, Plus One sizing:
If the wheel size is increased by two inches it is “Plus Two.” For example, a plus two fitment for a car with 16-inch original equipment wheels and tires would be 18-inch wheels and tires. As a general rule of thumb, Plus Two Sizing:
If the wheel size is increased by three inches it is “Plus Three.” For example, a plus two fitment for a car with 16-inch original equipment wheels and tires would be 19-inch wheels and tires. As a general rule of thumb, Plus Three Sizing:
