When your trailer’s loaded up, you want a wheel that can handle it without breaking a sweat. The Aluminum AM03 Series Gunmetal Gray Machined Trailer Wheel is rated for 1,740 lbs and meets DOT specifications, which means it’s built for real-world hauling strength. Its durable aluminum construction keeps weight down—just 13 lbs—while staying tough enough for long trips and frequent towing.
There’s nothing worse than having to constantly re-tighten lug nuts after every tow. This wheel solves that with steel inserts built right into the lug nut wells. They prevent wear and help keep the wheel securely seated on the hub. That’s extra peace of mind mile after mile, no matter how often you’re on the road.
Corrosion can ruin a good wheel fast, especially if it sits outside. This one’s made from rustproof aluminum with a clear coat on both sides to protect against scuffs and scratches. The gunmetal gray finish with a machined face gives it a clean, high-end look that holds up over time and keeps your setup looking fresh.
Getting the right fit shouldn’t be complicated. This wheel measures 13" in diameter by 4-1/2" wide, has a 5 on 4-1/2" bolt pattern, a 3.19" pilot diameter, and uses 1/2"-20 wheel bolts with a 0 offset. It’s sized right for standard 13" trailer tires and works seamlessly with acorn-style lug nuts that have a 60° cone seat like the #12CLN.
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Wow Harold, those wheels look great! I love the color of your boat too! Where do you mainly take your center console fishing boat out at, and what are you mainly fishing for? We have a Ranger, and like to dabble in some local bass fishing tournaments at the Lake of the Ozarks and Mark Twain Lake here in Missouri.

They do look great with those tires mounted. I am glad we were able to get them to you quick. When spring comes what kind of trailer are you going to be putting these on?
