Frequently Asked Questions
Most 305/35R24s run on a recommended cold inflation pressure range of around 35–45 PSI. However, one must always follow the recommended optimal air pressure stated in your placard or manual, depending on the tire model and your vehicle’s specifications.
To illustrate a 305/35R24 tire size, the 305 would be the tread width. The sidewall height of a 305/35 tire would be 305 millimeters — about 12 inches. The 35 signifies the aspect ratio, or sidewall height, which is 35% of the tread width. The R stands for radial construction, implying that the layers run perpendicularly from the bead. The 24 refers to the wheel size in inches, which the tire is designed to accommodate.
When properly mounted and inflated on a 24-inch wheel, a 305/35R24 tire is around 33.1 inches in overall diameter. Due to the 35% aspect ratio, tires have an extremely wide tread face of around 12 inches and a very low 4.2-inch sidewall height.
The most common tire sizes for 24-inch wheel diameters roughly range from 275/30R24 up to 355/25R24 and above, depending on the vehicle application. Moreover, wider, lower-profile fitments (305/35R24, 315/35R24, and 335/30R24) are popular upgrades on trucks, SUVs, and performance cars looking to get a plus-sized look.
Most manufacturers advise 305/35R24 tire rotation every 5,000–7,500 miles to ensure each wheel wears. However, the adequate rotation period differs due to factors such as alignment settings, driving conditions, driving type, etc. Thus, look up the rotation rate in your owner’s manual for your car and tire size.
