Displays tire radius, tire diameter, and tire circumference
Tire revolutions per mile and per kilometer
Lists dimensions for unloaded, static rolling, and dynamic rolling conditions
Uses tire pressure for calculating rolling radius, rolling diameter, rolling circumference, and revs per distance
Uses speed for calculating dynamic rolling radius, dynamic rolling diameter, dynamic rolling circumference, and dynamic revs per distance
Lists other tire sizes with similar dimensions
Everything you need to know about your tire dimensions.
Enter tire section, aspect ratio, wheel diameter, tire pressure, and a road speed. Calculate unloaded dimensions, static rolling dimensions, dynamic rolling dimensions, and lists tires with similar diameters.
