WIDTH & ASPECT RATIOExample: 18 x 9.50 – 8All of these dimensions are represented in inches.

18 - Outside diameter of the tire.• We do not advise changing one tire at a time, because each

manufacturer size might be different.

9.50 - Tire width. • If you purchase a tire that has a number wider than the one on

the sidewall of the tire you may have clearance issues and the tire may rub.

8 - Rim diameter. • You must always purchase a tire with the same rim diameter

specification otherwise the tire will not fit on the rim.
