Plus Sizing
Plus sizing wheels and tires has become the hottest trend among enthusiasts. Adding inches to the wheel diameter for wider, low aspect ratio tires can increase your car’s handling capabilities.
Plus Zero
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.
Plus One
This sizing mounts tires with an increased section width and a lower aspect ratio on wheels of a wider diameter. A Plus One fitment for a car with 13-inch original equipment wheels would use 14-inch wheels.
As a general rule of thumb, Plus One Sizing:
Increases section width by 10 mm.
Decreases aspect ratio by 10 points.
Increases rim diameter by 1 inch.
Plus Two
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 13-inch original equipment wheels would use 15-inch wheels.
As a general rule of thumb, Plus Two Sizing:
Increases section width by 20 mm.
Decreases aspect ratio by 20 points.
Increases rim diameter by 2 inch.
