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 handling capabilities and its appearance. The following are common plus sizes.
Increase the section width and lower the aspect ratio while retaining the wheel diameter. This replacement tire increases the contact area and lowers the tread profile for improved traction and quicker response.
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 14-inch original equipment wheels would be 15-inch wheels.
As a general rule of thumb, plus one sizing:
- Increases section width by 10 millimeters
- Decreases aspect ratio by 10 points
- Increases rim diameter by 1 inch
Increased wheel widths in plus sizing also contribute to greater tire stability and improved cornering and maneuverability. A plus two fitment for a car with 14-inch original equipment wheels would be 16-inch wheels.
As a general rule of thumb, plus two sizing:
- Increases section width by 20 millimeters
- Decreases aspect ratio by 20 points.
- Increases rim diameter by 2 inch.
Dealers have additional information for plus sizing ABS-equipped vehicles. Always consult your Toyo Tires dealer when changing the size of tires on your vehicle.
