What 265/75R16 means
The inputs are 265 mm nominal section width, a 75-percent aspect ratio, and a 16-inch nominal rim diameter. The R identifies radial construction. The width is not a wheel-width measurement, and the rim number is not the outside diameter of the tire.
Nominal sidewall height is 265 × 75 ÷ 100 = 198.75 mm. Adding two sidewalls to the 406.4 mm rim gives 803.9 mm (31.65 in) of nominal outside diameter.
A calculated reference
The manufacturer entry used for this page is LT265/75 R 16. LT is retained in the source record and matters beyond geometry. Normalizing the three geometric inputs does not establish equivalence to a passenger-designated tire or supply a load-capacity calculation.
Using a perfect-circle model, circumference is 2525.53 mm, equivalent to 395.96 revolutions per kilometer or 637.23 per mile. These are derived from unrounded diameter; actual rolling circumference also depends on the product and operating conditions.
Source and scope
General Tire’s Grabber APT source includes LT265/75 R 16, article 04504350000. It was checked on October 27, 2026. That record verifies the published marking used here; it does not turn these calculated dimensions into that product’s measured specification or establish availability. The LT prefix is preserved in the source record. This page does not calculate load capacity or remove that designation’s significance.
Use the exact product and vehicle requirements for load and speed ratings, permitted rim dimensions, inflation and clearance. Nominal geometry alone cannot verify fitment, braking behavior, handling or safety.
