The 6 on 5.5-inch bolt pattern is common on trailer wheels and hub assemblies, but matching the pattern alone does not guarantee fit. These five options include three trailer-wheel choices and two hub-and-drum kits. The black two-pack wheel is best for buyers prioritizing the listed 4,080-pound maximum load per rim; the silver two-pack is an alternative with a lower stated load limit. For brake components, choose the LIBRA kit for included self-adjusting electric brakes or the JADODE kit when you need drums without brakes.

eCustomRim Black Trailer Wheel Two-Pack
This pair of 15-by-6-inch black modular rims has a 6-on-5.5-inch lug pattern and a 4.25-inch center bore. The listed maximum load is 4,080 pounds per rim. The manufacturer describes the wheels as trailer-specific, rather than intended for general passenger-vehicle use.
Best for: Trailer owners replacing two wheels who want a black finish and the highest stated per-rim capacity among the listed wheel options. It was selected for its two-wheel format and clear load specification.
Check before buying: Confirm the trailer’s required wheel load, tire size, center bore, and bolt pattern. The listing advises consulting its fitment guide; a matching lug pattern alone does not establish complete fit.
eCustomRim Silver Trailer Wheel Two-Pack
This two-pack includes 15-by-6-inch silver modular trailer rims with a 6-on-5.5-inch bolt pattern and 4.25-inch center bore. Each rim has a stated maximum load of 2,860 pounds. The wheels are designed specifically for trailer applications.
Best for: Buyers seeking two silver trailer wheels whose required load capacity is within the listed limit. It was selected as the silver-finish alternative to the black two-pack.
Compare carefully: Its stated maximum load is lower than the other eCustomRim wheels in this selection. Avoid choosing it if the trailer’s wheel requirements exceed 2,860 pounds per rim, and verify fitment with the trailer specifications.
eCustomRim Black Trailer Wheel Single
This 15-by-6-inch black modular rim is listed with a 6-on-5.5-inch lug pattern, a 4.25-inch center bore, and a maximum load of 4,080 pounds. It is described as a trailer-specific wheel. Unlike the two-pack options, this listing is for one wheel.
Best for: Replacing a single matching wheel or buying the exact quantity needed. It was selected because it provides the same listed pattern, size, and maximum load as the black two-pack in a single-wheel option.
Check before buying: Confirm that your trailer calls for a 15-by-6-inch wheel and that its load requirement does not exceed the listed limit. The product information recommends checking the fitment guide.
LIBRA Hub Drum And Brake Kit
This kit combines two 6-on-5.5-inch hub drum assemblies with one right and one left 12-by-2-inch self-adjusting electric brake. Listed components include inner and outer cone bearings, grease seals, EZ-lube grease caps, and 1/2-by-20-thread cone wheel nuts. The product is described for 6,000–7,000-pound axles and says it works with Dexter and other brands in that axle range.
Best for: Buyers replacing hubs and adding or replacing electric brakes in one purchase. It was selected because the kit includes both hub drums and self-adjusting brake assemblies.
Check before buying: Verify axle capacity, brake dimensions, hub fit, and the required bolt pattern. Although compatibility is stated for certain axles, that does not confirm fit on every trailer.
JADODE 12-Inch Trailer Brake Drum Kit
This 6-on-5.5-inch hub drum assembly is listed for 5,200–6,000-pound axles and 12-by-2-inch electric or hydraulic brakes. The kit includes installed bearing races, inner and outer bearings, a grease seal, an EZ-lube grease cap, and six studs with 1/2-by-20 threads and nuts.
Best for: Trailer owners who need hub drums for the specified axle range and already have suitable brakes. It was selected as the drum-only alternative to the LIBRA kit.
Limitation: Brakes are not included. Confirm axle capacity, brake type, dimensions, and hub specifications before ordering.
Buying Guide: How To Choose A 6-On-5.5 Part
What does 6 on 5.5 mean?
It describes six wheel studs arranged on a bolt circle with a 5.5-inch diameter. Match that pattern to the trailer, but also check wheel diameter and width, center bore, stud thread, and load requirements. Do not rely on the bolt pattern alone to confirm fit.
How should you compare wheel load limits?
Compare the stated maximum load per rim with the trailer’s requirements. The black eCustomRim wheels list 4,080 pounds per rim, while the silver two-pack lists 2,860 pounds per rim. These figures are product specifications, not a substitute for checking the complete wheel-and-tire setup or axle limits.
Should you choose a drum-only kit or a brake kit?
Choose the LIBRA kit if you need hub drums and the included self-adjusting electric brakes, subject to confirming axle and brake fit. Choose the JADODE kit if you need drums for its stated axle range and will use compatible brakes you already have. Its brakes are not included.
What measurements should you verify?
Before ordering, compare the existing part’s bolt pattern, axle rating, drum diameter and width, bearing numbers, seal dimensions, center bore, and stud thread. If any specification is unknown, check the trailer or axle documentation or consult a qualified parts supplier.
Frequently Asked Questions
Is 6 on 5.5 the same as six lug?
No. “Six lug” indicates the number of studs; “6 on 5.5” also specifies the bolt-circle diameter. Both details are needed when checking a wheel or hub.
Will a 6-on-5.5 wheel fit every six-lug trailer?
No. The bolt pattern must match, but wheel size, center bore, load capacity, and other fitment details must also be suitable for the trailer.
Do the JADODE drums include brakes?
No. The listing describes the drums as replacements for 12-by-2-inch electric or hydraulic brakes, and states that brakes are not included.
Which listed wheel has the lower stated load limit?
The silver eCustomRim two-pack lists a maximum load of 2,860 pounds per rim. The black eCustomRim options list 4,080 pounds per rim.
