Tire dimensional specification decoding and sidewall data interpretation on the 2023 Chevrolet Blazer are regulated by tire sidewall embossed lettering, industry sizing standards, and wheel rim diameters.
How to Fix It:
-
Locate Sidewall Code: Look at the outer sidewall of your tire to find the alphanumeric series starting with a letter such as P or LT (e.g., P235/65R18).
-
Identify Width and Ratio: Read the first three numbers as the tire width in millimeters, followed by the slash and two-digit aspect ratio representing sidewall height.
-
Check Rim Size: Note the letter R (radial) and the final two-digit number indicating the exact wheel rim diameter in inches.
