Before ordering
Compare the complete size, load index and speed rating with your vehicle’s approved requirements. Confirm wheel width, wheel load capacity and clearance as well as diameter. A tire’s dimensions do not establish an OEM vehicle application. If changing tire size or type, have the combination and operating pressure checked by a qualified tire professional.
Questions about 225/60R18
What do the numbers in 225/60R18 mean?
The size uses a nominal 225 mm section width and an aspect ratio of 60; the sidewall height is expressed as a percentage of that nominal width. R denotes radial construction and 18 is the wheel diameter in inches. Nitto lists this exact tire at 28.62 inches overall diameter and 8.98 inches overall width on the 6.5-inch measuring rim.
What wheel width is approved for this 225/60R18 tire?
Nitto lists 6.0–8.0 inches as the approved rim-width range for stock number 261560. Its 6.5-inch measuring rim is the reference for the published dimensions, not the only approved width. The wheel must also have the correct 18-inch diameter and be suitable for the vehicle and required load.
What does the 104V XL marking tell me?
104 is the tire’s load index and V is its speed symbol. XL means Extra Load; it is a load designation, not a statement of the number of physical casing plies. Use the complete size and service description when checking a replacement against the vehicle’s approved requirements; the tire model name alone is not enough.
Is 50 psi the pressure I should run in this tire?
No. The listed 1,984 lb at 50 psi is Nitto’s maximum load/inflation rating. It is not a recommended pressure for every vehicle. Follow the applicable vehicle and tire guidance, and have the operating pressure confirmed when changing tire size, type or load requirements.
Will this 225/60R18 tire fit any vehicle with 18-inch wheels?
No. A matching 18-inch wheel diameter is only one requirement. Check the approved 6.0–8.0-inch rim-width range, complete 104V service description, wheel load capacity and vehicle clearance. The published 28.62-inch diameter is useful for comparison, but does not prove vehicle fitment or that a lift or modification is unnecessary.
