Questions about 305/50R20
What does 305/50R20 mean on this A/T4W?
305 is the nominal section width in millimetres; 50 is the sidewall aspect ratio as a percentage of that width. R identifies radial construction, and 20 is the wheel diameter in inches.
What wheel width does the 305/50R20 size require?
The approved rim-width range is 8.5–11 inches for a 20-inch wheel. The wheel’s own tire-size and load limits must also be suitable.
What does the 120T service marking mean?
120 is the load index and T is the speed symbol. Compare both with the vehicle’s tire requirements; the wheel diameter alone does not establish the correct replacement.
Is the 305 mm size width an exact clearance measurement?
It is a nominal size designation. Measured tire dimensions use a specified measuring rim, so confirm the actual wheel setup and available vehicle clearance before changing tire size.
