Tires 101: Plus Sizing Tires

Plus sizing wheels and tires is a popular trend among car enthusiasts. 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). Once something done after the car was purchased, it is now common for auto dealerships to offer wheel and tire upgrades at the time of purchase.

If the wheel 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;” by two it is “Plus Two” and so on. For example, a plus one fitment for a car with 17-inch original equipment wheels and tires would be 18-inch wheels and tires.

Increasing the width of a tire and/or 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.

It is important to make sure you choose the right tires when plus sizing. Use the Toyo Tire Finder to find plus sizing options for your vehicle and then work with a tire professional to find the right wheel and tire combination.
