Standard Golf Cart Tire Sizing Format
Standard golf cart tire sizing uses the format XX x YY – ZZ. This American system shows measurements in inches and makes tire shopping easier for most people. Let’s break down what each number means:
XX = Overall Diameter (tire height in inches)
YY = Width (tire width in inches)
ZZ = Wheel Size (rim diameter in inches)
For example, a 23×10-14 tire means:
23 inches tall (overall diameter)
10 inches wide (width)
Fits a 14-inch wheel size
Metric Golf Cart Tire Sizing Format
Metric golf cart tire sizing uses the format XXX/YY-ZZ. This European system mixes millimeters and inches, which can seem tricky at first. Here’s how to read it:
XXX = Width in millimeters
YY = Aspect Ratio (sidewall height as percentage of width)
ZZ = Wheel Size in inches
For example, a 205/50-10 tire means:
205 millimeters wide
50% aspect ratio (sidewall is 50% of tire width)
Fits a 10-inch wheel
Stock golf cart tires typically measure 18-18.5 inches in height and 8 inches wide. Many stock golf cart tires clock in at 18 inches tall and 8.5 inches wide when full of air at the proper tire pressure. These stock tire dimensions work on 8-inch wheels and provide good performance for most golf cart uses.
Common stock tire sizes include:
18×8.5-8 (most common)
18×8-8
20.5×8-8 (slightly taller)
