Popular comparisons with the 265/75R16
Load index & speed rating — how to read them
The size code is only half of the sidewall. After it comes a load index and a speed letter, like 121R. Load index 121 means one tire carries up to 3,197 lbs at its rated pressure; speed rating R means up to 106 mph. A replacement tire must meet or exceed both numbers on your vehicle's door-jamb placard. Calculate another size or compare two sizes.
