All You Need To Know About P245/70R17 Tire Size
P245/70R17 has a 245 mm section width, a 70% aspect ratio, and fits a 17-inch wheel, producing a calculated overall diameter of approximately 30.5 inches and a sidewall approximately 6.8 inches high. The separately designated 245/70R17 has the same nominal dimensions, but P-metric and Euro/non-P metric versions can differ in their load-capacity calculations and inflation tables. A separate LT245/70R17 designation also exists; LT-metric and P-metric tires use different load and inflation standards and should not be treated as automatically interchangeable.
