What’s the difference between a 265/75 and a 265/70 tire? With all the metrics talk it’s hard to tell one from the other but there is an inch of difference between the two. That’s an LT265/75R16 Falken WildPeak shown with a well-used LT265/70R16 BFG All-Terrain. The BFG All-Terrain measures 30.6 inches in diameter. The Falken WildPeak measures 31.6 inches in diameter. Both offer a 10.4-inch section width.
