For an 18.4-38 tractor tire, first confirm that your tractor calls for radial construction, then verify the tire’s size, load requirements, and tube or tubeless setup. The BKT TR135 is a field-focused tire option, while the JUSTUBES.COM set includes two tires and matching tubes. The Carlisle listing specifies an angled agricultural tread. The other two products are replacement inner tubes, not tires. The product details provided do not confirm radial construction for the three tire listings, so check the seller’s specifications before buying if radial construction is essential.
| Product | Best suited for | What to verify |
|---|---|---|

| JUSTUBES.COM tire set | Buyers needing two tires and tubes | Radial construction and tractor requirements |
| Carlisle CSL24 R-1 | Tractor, sprayer, or harvester use | Construction type and exact application |
| 16.9-38/18.4-38 tube | Replacement tube for a compatible tire | Valve and tire fitment |
| TYK multi-fitment tube | Tube replacement for radial or bias tires | Size and TR218 valve suitability |
BKT TR135 R1 For Soil Tillage
The BKT TR135 is an 18.4-38 R1 tire described as suitable for soil-tillage applications. Its listed features include a reinforced casing and a cut-and-chip-resistant compound, along with traction, self-cleaning properties, and load capacity for challenging ground.
Best for: Buyers prioritizing agricultural traction and tillage use. It was selected because its description directly addresses field performance and tire durability. Caution: The supplied listing does not specify radial construction. Confirm the construction type, load requirements, and fitment before purchase if you specifically need a radial tire.
JUSTUBES.COM 10-Ply Tire Set
This package includes two 18.4-38 agricultural tires and two matching tubes. The tires have a 10-ply rating and an R1 tread pattern. The listing describes the tread as intended to provide traction in field conditions.
Best for: Buyers replacing a pair of tires who also need tubes in the same order. The bundled format is the main reason to consider it over a tire-only listing. Caution: The product details do not identify the tires as radial. A 10-ply rating and R1 tread pattern alone do not establish radial construction, so verify that specification and the tractor’s required load capacity.
Carlisle CSL24 R-1 Tire
The Carlisle CSL24 listing identifies an 18.4-38, 10-ply tire with an angled tread. Its description highlights grip and a cut- and chip-resistant tread, and names tractors, sprayers, and harvesters as intended applications.
Best for: Buyers comparing an agricultural tire for equipment used across field tasks. The listed tread and application details make it useful to evaluate for tractor or machinery use. Caution: The listing does not confirm radial construction, and its name also says “Lawn & Garden.” Confirm the exact tire type and intended fitment with the seller before ordering.
16.9-38/18.4-38 Replacement Tube
This is an inner tube, not a tire. It is listed as a replacement for 16.9-38 and 18.4-38 tires. The product description says it uses thick, uniform rubber intended to provide strength, flexibility, and abrasion resistance.
Best for: Buyers replacing a tube in a compatible tire. Its stated size range includes 18.4-38, which makes it relevant to owners checking tube options for that tire size. Caution: The provided details do not specify the valve stem type or confirm suitability for every radial tire. Match the tube to the tire and wheel requirements before purchase.
TYK Multi-Fitment TR218 Tube
This TYK Industries product is a single inner tube listed for 16.9-38 and 18.4-38 tires. The description says it has a TR218 valve stem and is suitable for radial or bias tires. It also describes thick butyl rubber and a reinforced seal around the valve stem.
Best for: Buyers who need a replacement tube and have confirmed that the TR218 valve and listed size suit their setup. Its explicit radial-or-bias wording distinguishes it from the other tube listing. Caution: It remains a tube, not a radial tire. Confirm the tube’s size and valve configuration before installation.
Buying Guide: How To Choose An 18.4-38 Tire
Does the listing actually specify radial construction?
Do not assume a tire is radial because it has an 18.4-38 size, an R1 tread, or a 10-ply rating. These details describe size, tread category, or rating—not necessarily construction. The tire descriptions above do not confirm radial construction. Ask the seller or consult the full manufacturer specification if radial construction is required.
What do R1 tread and ply rating tell you?
R1 identifies an agricultural tread pattern associated in these listings with field traction. A ply rating is a tire strength or load-related designation, but it does not replace checking the tire’s stated load capacity at the operating conditions recommended for your tractor. Compare the full specifications with the tractor manual and the tire being replaced.
Should you buy a tire set or a tube separately?
Choose the JUSTUBES.COM set if you need two tires and two tubes and have confirmed its specifications meet your needs. Choose a tire-only option when you need a particular tread or application. Buy an inner tube only when a tube is required by your tire and wheel setup; confirm its size and valve stem before ordering.
What should you check before installation?
- Confirm the tire size and construction against the tractor’s requirements.
- Compare load specifications and intended agricultural use.
- Check whether the tire requires a tube and verify the tube valve type.
- Confirm the seller’s details when the listing name and application description seem inconsistent.
