Specifications side by side

How the picks were chosen

We started with 26 BKT tires listed in our catalog that have live prices. After removing near-duplicates and models with incomplete size data, we shortlisted 15 that cover the main use cases. Selection was based solely on the seller's stated specifications: tire size, radial or bias designation (where visible in the size), ply count, and tread pattern. We did not test any unit. Prices shown next to each pick update in real time from the product listing; the number you see is what the seller is asking at the moment the page loads.

Picking the right one for you

Tire size: what the numbers mean

BKT farm and industrial tires are labeled with sizes like 710/70R38 or 23.1/-30. The first number is section width in millimeters (for metric sizes) or inches (for high-flotation and old-style numbers). The second number is the aspect ratio (height to width) for radial tires, expressed as a percentage. The following letter R indicates radial construction; a hyphen or no letter indicates bias ply. The final number is the rim diameter in inches. For example, a 23.1/-30 tire has a 23.1-inch section width, a bias ply, and fits a 30-inch rim. Always match the tire size to what the vehicle manufacturer specifies.

Ply count and load range

The ply count (or load range) is a measure of relative strength and the maximum inflation pressure that a tire can carry. A higher number like 8PR or 14-ply indicates a stronger carcass, meaning you can run a higher load at a higher pressure. For example, the LG-306 has a 14-ply construction, which is the highest among our picks. On the other hand, many BKT farm tires in this list do not state a ply count; in that case, contact the seller or check the sidewall for a load index or load range letter. Federal standard 49 CFR 571.119 requires that tires list a load capacity and a rim size, so look for those details on the tire itself.

Tread types: R-1, R-1W, R-3, and beyond

BKT uses standard classes for tread depth and pattern. R-1 is a general-purpose agricultural tread, with moderate bars for traction in dry and slightly wet fields. R-1W is a wet-field version with deeper bars. R-3 is a turf tread designed to minimize damage to lawn surfaces. When you see a tire labeled E3 or L3, it is for earthmover applications (loader or grader) and has a more aggressive design. For ATV and UTV tires, look for the tread description: 'Mud Terrain' in the seller's specs means the tire has a deep lug pattern for off-road mud. Choose a tread type that matches the primary surface you work on.

Radial vs. bias ply

Radial tires have ply cords at 90 degrees to the tread, which gives a more flexible sidewall and a larger footprint at lower pressures. They are common on modern tractors for improved ride comfort and lower compaction. Bias ply tires have cords at an angle and are stiffer on the bottom, which some operators prefer for heavy loads on hard surfaces. The Biastire's TR135 in this guide is an example of a bias rear tractor tire. In our selection, the majority of large farm tires are radial, while the smaller implement and lawn tires are bias. Check your equipment manual to know which type it expects.

Vehicle application and load index

BKT lists many tires for both farm and industrial vehicles. For example, the PL801 is an industrial forklift tire and should not be used on a tractor. Others, like the TR 387, are marked for farm use but also work on graders. When you choose a tire, make sure the speed symbol and load index match your vehicle's gross axle weight. Federal regulations (FMVSS 119 for vehicles over 10,000 lb, and FMVSS 139 for lighter vehicles) require that the tire's load capacity at the vehicle's recommended inflation pressure be high enough for the highest GAWR. If you do not know the load capacity, that information must be on the sidewall or in the tire's documentation.

Specialty sizes for ATV and lawn equipment

For ATVs and UTVs, BKT offers dedicated tires like the BogMax M/T and sets like the AT 171. These are small compared to farm tires, but still have ply counts and a recommended rim width. Lawn mower tires, such as the LG-306, use a different size format: 26x12.00-12, where the first number is overall diameter in inches, the second is section width in decimals, and the last is rim diameter. Always verify that the tire's overall diameter is compatible with your machine's fenders and axle clearance. A tire that is too wide can rub, and one that is too tall can change the gearing.

Questions

What does the 'R' in a tire size like 710/70R38 stand for?

The R stands for radial construction, meaning the ply cords run radially (at 90 degrees) from bead to bead. Radial tires have flexible sidewalls, which improves ride comfort and allows a larger footprint at lower pressures. Most modern farm tractors use radial tires. If a size has no R and uses a hyphen, like 23.1/-30, it is a bias-ply tire.

How do I find the load range or ply count for a BKT tire if it is not listed in the online description?

The load range and ply count are typically molded onto the tire's sidewall. In the absence of that information, you can contact the seller directly or visit the TIA's resource page for tire service information. The U.S. federal standards (49 CFR 571.119, 571.139) require that load capacity and tire dimensions be marked, so the information must be present on the physical tire.

Can I use a BKT farm tire on the highway?

Yes, but only within the speed and load limits specified by the tire's speed symbol and load index. Farm tires are often used for short highway trips between fields, but they may be marked with a lower speed symbol than highway truck tires. Check the sidewall for the speed symbol. For sustained highway use, a rib implement tire like the AW702 is a better choice.

What is the difference between R-1 and R-1W tread?

R-1 is a standard agricultural tread with bars that provide traction in soil. R-1W is the same general pattern but with deeper, more aggressive bars that are designed to work better in wet or muddy conditions. The RT 657 in this guide is labeled R1W, making it a good pick for wet fields. R-3 is a turf tread with less traction but gentler on grass.
