A strong 16-ply trailer tire should match your trailer’s required size and load capacity, and suit owners hauling heavy RVs, fifth wheels, or utility trailers. Among these options, the Libra Trailer Parts All Steel 235/80R16 set pairs an all-steel build with a stated 4,190-pound capacity per tire, while several 235/85R16 choices list capacities around 4,540 pounds. Those sizes are not interchangeable by assumption: confirm the tire size your trailer requires before choosing.
This roundup compares ten trailer-duty listings, including individual tires and sets of four, so check the actual quantity and mounting requirements before ordering. Load range, load index, ply rating, and size all matter; use your trailer and tire documentation to verify a suitable match rather than selecting by ply count alone.
The Libra Trailer Parts All Steel 235/80R16 set is the leading choice for buyers whose trailer calls for that size: it is a set of four, has all-steel construction, is rated 16-ply, and lists a 4,190-pound load capacity per tire. It combines a clearly stated heavy-trailer application with a size shared by several options here. If your trailer instead requires 235/85R16, compare the higher listed capacities of the 235/85R16 tires, but do not substitute sizes without confirming compatibility.

View on AmazonWhy matching the tire size matters
Do not treat 235/80R16 and 235/85R16 as interchangeable just because both appear in this 16-ply roundup. The listings identify them as separate tire sizes, and the 235/85R16 options generally show higher load capacities here: 4,540 or 4,541 pounds versus about 4,189 or 4,190 pounds for the 235/80R16 options. Those figures do not establish that the taller size will fit your trailer or wheel well.
Check the size specified by the trailer maker and the tire currently fitted, then confirm any proposed change against the trailer documentation and a qualified tire professional. Also verify rim diameter: these products list a 16-inch rim size, but that alone does not confirm full fitment.
A capacity figure is not permission to exceed the trailer’s rated limits or to alter its approved tire setup.
What a 16-ply listing does—and does not—tell you
A 16-ply label alone does not tell you whether a tire suits your trailer; compare the listed size, load range, and capacity as well. Several 235/80R16 products pair a 16-ply rating with load range H and capacities around 4,189–4,190 pounds. The Cosmo Stray Kat IV Plus is a useful contrast: it is described as 16-ply equivalent, but its listed load range is G and capacity is 4,080 pounds.
The 235/85R16 choices list about 4,540–4,541 pounds, but only suit a trailer if that size is approved. Product titles also differ in quantity: some say set of four while others describe one tire, and the specifications may say tire only.
Check the order quantity and whether rims are included; the Libra and Gremax listings explicitly say rims are not included.
How to Choose 16-Ply Trailer Tires
Required tire size
Start with the exact size specified for your trailer, rather than choosing a tire because its capacity looks higher. This selection includes 235/80R16 options, such as the Libra Trailer Parts All Steel 235/80R16 and Gremax All Steel 235/80R16, as well as 235/85R16 options such as Gremax All Steel 235/85R16. The former group lists capacities around 4,189–4,190 pounds; the latter lists roughly 4,540–4,541 pounds.
That difference does not establish fitment or authorize a size change. If your trailer calls for 235/80R16, prioritize that size; if its approved specification is 235/85R16, compare products in that size.
Confirm the size in the trailer documentation or with a qualified tire professional before ordering.
Capacity and load range
Look for a listed capacity and load range that meet your trailer’s requirements, allowing for the actual load carried by each tire. Most of the 235/80R16 H-rated options here list about 4,189–4,190 pounds, while the 235/85R16 H-rated products list about 4,540–4,541 pounds. The Cosmo Stray Kat IV Plus is listed as load range G with 4,080 pounds, despite its 16-ply-equivalent description.
These specifications are not interchangeable with your trailer’s ratings: compare them with the tire and vehicle documentation and account for how load is distributed. Buyers who need the specified 235/80R16 may find the roughly 4,190-pound listings relevant; those whose approved size is 235/85R16 can consider the higher listed capacities in that size.
Individual tire or set quantity
Check how many tires are included before deciding whether a listing fits your replacement need. Several titles explicitly say set of four, including the Libra Trailer Parts All Steel 235/80R16, Transeagle 235/80R16 Set, and Nebula Grand Trailer-N’ Other products are presented as a tire, including the Gremax All Steel 235/80R16 and Cosmo Stray Kat IV Plus 235/80R16.
Specifications often say tire only, which indicates that rims are not part of the listed components; the Libra and Gremax product descriptions also explicitly state that rims are not included. If you are replacing a full set, favor a listing whose quantity clearly covers that need.
If you need one tire, verify the final order quantity rather than relying on a bundle-style title alone.
Which 16-ply trailer tire should I choose?
For a trailer specified for 235/80R16 and a four-tire replacement, choose the Libra Trailer Parts All Steel 235/80R16: it is a set of four with all-steel construction and 4,190-pound capacity per tire. The Transeagle 235/80R16 Set is another set option in that size, while the Gremax All Steel 235/80R16 is listed as an individual tire. If your trailer is approved for 235/85R16, the Gremax All Steel 235/85R16, Nebula Grand Trailer-N’ 007, and Transeagle 235/85R16 Set list capacities around 4,540–4,541 pounds.
For buyers weighing a lower listed capacity in the correct 235/80R16 size, the Cosmo Stray Kat IV Plus 235/80R16 is a trailer-duty option at 4,080 pounds, but verify that its load range and capacity meet your requirements.

Frequently Asked Questions
How do I confirm whether 235/80R16 or 235/85R16 is correct for my trailer?
Use the tire size specified on the trailer’s placard or in its owner’s documentation, and confirm it with the trailer manufacturer if unclear. The two sizes are not automatically interchangeable. Before choosing a replacement, check that the tire fits the wheel and trailer and meets the manufacturer’s requirements.
How much load capacity should each trailer tire provide for my loaded trailer?
Each tire must meet the capacity required for its share of the trailer’s loaded weight, following the trailer manufacturer’s guidance. Check the load rating and capacity listed for the exact tire, and account for how the load is distributed. Do not assume the trailer’s total weight is divided evenly across every tire.
Can I replace a trailer tire with a different load range or ply rating?
Only if the replacement meets the trailer manufacturer’s requirements for size, load capacity, and other fitment details. A ply rating alone does not establish suitability, and a different load range may have a different stated capacity. Confirm the proposed tire against the trailer documentation or ask a qualified tire professional before replacing it.
Should I choose a 235/85R16 tire for its higher listed capacity?
Choose that size only if your trailer is approved for 235/85R16. The listed 235/85R16 options have capacities around 4,540–4,541 pounds, but a higher capacity does not make a different size compatible. Confirm the required size and fitment first, then compare the capacity of options that meet those requirements.
Do I need a set of four or an individual replacement tire?
Match the quantity to your replacement need and the tire condition across the trailer. This roundup includes products sold as sets of four and an individual Gremax 235/80R16 tire. Check the listing quantity carefully, and confirm that any replacement matches the trailer’s required size and load specifications.
Final Words
Start with the size specified for your trailer, then verify the required capacity against its loaded weight and manufacturer guidance. For a trailer calling for 235/80R16 and a four-tire replacement, the Libra Trailer Parts All Steel set is the leading choice here, with 4,190 pounds listed per tire. If your trailer specifies 235/85R16, compare options in that size rather than substituting.
Confirm fitment before ordering.
