Most mainstream Club Car, E-Z-GO, and Yamaha golf carts use a 4×4-inch bolt pattern, also written 4×101.6 mm, but that does not make every wheel universal. You still need to confirm lug-nut thread, center clearance, wheel offset/backspacing, width, load rating, and tire diameter.
The bolt pattern is only the first fitment check. This guide explains what the numbers mean, how to measure a 4-lug pattern, and where owners commonly make mistakes when mixing wheels between brands.
What does 4×4 bolt pattern mean?
The first “4” is the number of wheel studs or lug holes. The second “4” is the diameter, in inches, of the circle passing through the centers of those studs. In metric form, 4 inches equals 101.6 mm, so 4×4 and 4×101.6 describe the same bolt circle.
Do not confuse 4×101.6 with the automotive 4×100 pattern. They are close enough to look similar but not the same. A wheel should sit naturally on the studs without being forced sideways into alignment.
Common bolt patterns by golf cart brand
| Brand / family | Common bolt pattern | Important note |
|---|---|---|
| Club Car DS, Precedent, Tempo, Onward | 4×4 in / 4×101.6 mm is common | Confirm lug hardware and wheel clearance for the exact model. |
| E-Z-GO TXT, RXV and many Express models | 4×4 in / 4×101.6 mm is common | Brake and body clearance can differ by model and wheel size. |
| Yamaha G-Series, Drive/G29, Drive2 | 4×4 in / 4×101.6 mm is common | Yamaha commonly uses metric lug hardware rather than the SAE hardware found on many Club Car/E-Z-GO carts. |
| Other or specialty carts | Varies | Measure before ordering. Do not assume the big-three pattern applies. |
This is why our answer to “are golf cart wheels universal?” is no. A shared bolt circle helps, but it is not the whole fitment system.
How to measure a 4-lug golf cart bolt pattern
On a four-lug hub, measure from the center of one stud to the center of the stud directly opposite it. A standard golf-cart 4×4 pattern should measure about 4 inches or 101.6 mm across that circle.
Remove decorative hub caps before measuring. Some covers can make a four-lug hub look like a different pattern.
Lug thread is separate from bolt pattern
Two carts can have the same 4×4 pattern and still use different lug nuts. Club Car and E-Z-GO commonly use 1/2-20 SAE hardware on many models, while Yamaha commonly uses metric M12x1.25 hardware. Verify your cart rather than ordering nuts based only on the wheel listing.
The nut must also have the correct seat style for the wheel. A mismatch between conical, ball, or flat seating surfaces can prevent proper clamping even when the thread itself is correct.
Center bore and brake clearance
The wheel’s center opening must clear the hub, dust cap, brake components, and any protrusions. A bolt pattern can line up perfectly while the center of the wheel physically contacts the hub.
This is especially important with nonstandard wheels, spacers, disc-brake conversions, and newer carts with larger brake packages.
Offset and backspacing change where the wheel sits
Offset describes the location of the wheel’s mounting face relative to the wheel centerline. Backspacing describes how far the inner edge of the wheel sits behind the mounting face. Both affect inner suspension clearance and how far the tire sticks outside the body.
A wheel with the correct 4×4 pattern can still rub a shock, leaf spring, tie rod, body panel, or fender if the offset is wrong. Read our golf cart rims and tires fitment guide before combining a new wheel with a taller or wider tire.
Tire diameter still matters
Bolt pattern tells you whether the wheel attaches to the hub. It does not tell you whether the complete tire fits under the cart. An 8-inch, 10-inch, 12-inch, or 14-inch wheel can carry tires with very different overall diameters.
For stock-height versus lifted fitment, use the golf cart tire size guide. Larger tire height is usually the main reason a wheel package starts rubbing.
Why 4×100 automotive wheels are a poor shortcut
4×100 mm and 4×101.6 mm are not the same bolt pattern. The difference is small on paper, but the wheel should not be pulled into position by tightening the lug nuts. That can load the studs unevenly and make centering unreliable.
What to verify before ordering wheels
- Exact bolt pattern
- Lug-stud thread and nut seat
- Center bore / hub clearance
- Wheel width
- Offset and backspacing
- Wheel load rating
- Overall tire diameter and width
- Lift-kit and steering clearance
Bottom line
4×4 (4×101.6 mm) is the dominant golf-cart bolt pattern, especially across common Club Car, E-Z-GO, and Yamaha models. Treat that as a starting point, not proof of universal fit. Confirm the hardware, center clearance, offset, wheel width, load rating, and tire size before you buy.
