What we typed
Set of four 18-inch alloy rims without tires
Diameter and quantity are the load-bearing words here. Four 18-inch wheels is a very different shipment from one, and the description has to say so.
A single rim ships as a heavy parcel, but a set of four is usually crated or palletized at 80–160 lb depending on diameter and material. Alloy wheels are heavy and the boxes are large, so expect real weight, oversize dimensions, and often freight for a full set rather than a flat parcel rate. Whether yours goes parcel or pallet depends on how you split the set, so start from real dimensions and let the quote sort the path.
Sized at 22 × 22 × 11 in and 26 lb, the four-rim example below routes to a freight review rather than an instant parcel rate.
To build this example we gave the SMKlog calculator “Set of four 18-inch alloy rims without tires” and the long haul from Miami, FL 33101 to Seattle, WA 98101 on 2026-07-24. Its verdict follows unedited, and it is not a parcel label.

Packed weight 26 lb (12 kg).
Miami, FL 33101
to Seattle, WA 98101
Florida to Washington State, about as long as a domestic lane gets. Both ends are real ZIPs run against live tables.
A parcel label never appears for this one. Sizing came back at 22 × 22 × 11 in and 26 lb, and a shipment built that way falls outside what USPS, UPS, and FedEx will carry as an ordinary parcel. Rather than sell a label destined to be repriced or refused mid-route, SMKlog sends the set to a person for a freight quote.

All the rows below were priced on 2026-07-25 over the identical Miami, FL to Seattle, WA lane used above, which isolates one variable: the contents of the box. Any row is clickable and opens the calculator preloaded with that description and route.
| What we typed | Packed box | Packed weight | Cheapest quote |
|---|---|---|---|
| Single 17-inch alloy wheel rim without a tire | 20 × 20 × 10 in | 26 lb | $50.36 UPS Ground |
| Single 20-inch truck alloy wheel rim without a tire | 24 × 24 × 10 in | 40 lb | $65.52 UPS Ground |
| Set of four 17-inch alloy wheel rims without tires | 20 × 20 × 10 in | 25 lb | freight review — past parcel limits |
Between the cheapest and dearest priced rows sits $15.16 on the very same route, and the whole gap comes from the box rather than the brand. Where a row shows no price, nothing is missing: the carrier declines that configuration as a parcel, so it goes to review. Rates track the carriers' own tables, so quote yours before the tape goes on.
A boxed set occupies about 30 × 30 × 30 in. One box per rim with cardboard rings over each face, or four wheels banded to a pallet; bare rims touching in transit is the one setup to rule out.
Sets of four run 80–160 lb. As always the bill takes the larger of real and dimensional weight, so slack in the packaging translates into cost. Measure the finished shipment, not the wheels.
The combination of size, weight, and lane pushes a full set past normal parcel limits, so this Miami to Seattle shipment prices through a freight review instead of a rate card. Pallet dimensions, freight class, and pickup type set that number; carrier zone charts never enter into it.
Think in terms of 30 × 30 × 30 in for a boxed set. Either give each rim its own box with cardboard rings guarding the face, or band the four of them onto a pallet and go freight. Bare rims must never ride touching one another; the finish scuffs at the first vibration.
A four-wheel set packs to 80–160 lb. The billed amount follows the higher of the scale and the dimensional formula (length × width × height over the carrier divisor), which makes weighing and measuring the finished package a prerequisite for quoting; light guesses come back later as carrier corrections.
Up to two rims, heavy parcels make sense. Once all four travel together, one palletized freight shipment usually beats four separate oversize boxes on both cost and risk, since every extra box is another chance for handling damage.
Isolation above all: each rim boxed on its own, cardboard rings or foam across the face and lip, and no bare wheel ever resting against another. Alloy and painted finishes mark at the slightest rub.
Billable weight, lane, and speed, in combination. A packed set measuring 30x30x30 inches at 120 lb rates on its dimensional weight of about 194 lb (L x W x H / 139), since that figure tops the actual one. What remains is the zone distance and the choice between ground and expedited. Give the calculator your true route and packed size for live USPS, UPS, and FedEx pricing.
Full sets belong on UPS or FedEx ground; the USPS ceiling of 70 lb per box rules a 120 lb set out unless you split it up. Ground handles large, heavy boxes most economically anyway. Whichever carrier gets the job, purchase the label online at commercial rates and pocket the usual 20-40% versus walking up to the counter.
