BFG All-Terrain T/A KO2 | 215/75R15 100S

The BFGoodrich All-Terrain T/A KO2 215/75R15 100S is designed for 15 inch wheels and fits rims between 5.5 and 7.0 inches wide. That range aligns well with many factory steel wheels used on 1950s through 1970s American cars and light trucks. The 27.70 inch overall diameter closely matches common bias ply replacements like G78-15, making it a practical upgrade without drastic geometry changes.

Fitment still depends on wheel width, offset, and suspension condition. Vehicles originally running narrower bias ply tires may experience slightly increased section width at 9.0 inches, which can affect inner fender clearance and steering effort at low speeds.

The 27.70 inch diameter keeps ride height close to many original fitments, so vertical clearance is generally not a concern. However, the radial construction produces a squarer shoulder and wider contact patch compared to bias ply equivalents, which can bring the sidewall closer to control arms and fender lips.

Under compression or full steering lock, clearance becomes more critical. Vehicles with worn bushings or lowered suspension may experience rubbing. Careful checking at full lock and during suspension travel is recommended before committing to long-term use.

The recommended rim width range of 5.5 to 7.0 inches aligns well with many original factory wheels from classic American vehicles. A 6 inch wheel is ideal, producing the listed 9.0 inch section width and proper sidewall profile.

Mounting on narrower wheels can increase sidewall bulge, which may affect steering precision and heat buildup. Wider wheels within the range will flatten the tread slightly, improving contact patch stability but potentially increasing steering effort at low speeds.

The BFGoodrich All-Terrain T/A KO2 215/75R15 100S is specifically designed for mixed use, including pavement, mud, sand, and snow. Its all terrain design makes it ideal for classic trucks or SUVs used both on road and off road.

For purely show cars or restoration builds, the modern tread and RBL sidewall may not match period correct styling. For drivers prioritizing usability, it offers a strong balance of durability and traction.

The 27.70 inch diameter closely aligns with several classic bias ply sizes such as G78-15 and 7.10-15. This helps maintain original ride height and visual proportions.

Small variations may slightly affect speedometer readings. A minor difference in revolutions per mile can result in a slight speed reading variance, typically within acceptable limits for most classic vehicle applications.

The BFGoodrich All-Terrain T/A KO2 215/75R15 100S is slightly wider and may have a marginally different diameter compared to a 205R15. The difference is usually small but noticeable in stance and contact patch.

This upgrade increases grip and stability but may slightly alter speedometer accuracy. Clearance should be verified, particularly in vehicles with tight front suspension geometry.

With 751 revolutions per mile, the tire maintains a diameter close to many original sizes. Minor differences can cause small speedometer deviations.

In most cases, the speedometer may read slightly slower or faster depending on the original tire diameter. The variation is typically minimal and acceptable for non calibrated classic vehicles.

The radial construction and interlocking tread design provide stable highway performance. Tracking is more predictable than bias ply tires, especially at higher speeds.

The S speed rating supports speeds up to 112 mph, which is more than adequate for most classic vehicles. Heat buildup is controlled well under normal driving conditions, making it suitable for extended highway use.

The 75 series sidewall provides good cushioning over rough surfaces. Combined with radial construction, it delivers a smoother ride than bias ply tires.

However, the all terrain tread can introduce slight road noise. This is a tradeoff for increased traction and durability across varied surfaces.

The tire carries the three peak mountain snowflake rating, indicating strong snow traction performance. It performs well in cold conditions and light snow.

Deep snow and ice still require cautious driving. The tread design helps maintain traction, but braking distances can increase compared to dedicated winter tires.

The load index 100 corresponds to a maximum load capacity of 1,765 pounds per tire at 50 psi. This is sufficient for many classic cars and light trucks.

Operating below maximum load improves longevity and ride quality. Overloading can increase heat buildup and accelerate wear.

The load rating supports moderate weight vehicles, including classic trucks and full size sedans. It is not intended for heavy duty commercial loads.

For vehicles near the upper weight limit, maintaining proper inflation is critical to prevent excessive heat buildup and sidewall stress.

With 15/32 inch tread depth, the tire offers extended wear and strong traction over time. Deeper tread also improves off road capability.

As the tread wears, traction in mud and snow decreases. Regular rotation helps maintain even wear and prolong service life.

Rotation every 5,000 to 7,000 miles helps maintain even tread wear. This is especially important for all terrain tires.

Uneven wear can affect traction and handling. Regular rotation extends tire life and maintains consistent performance.

Inflation should be adjusted based on vehicle weight and usage. The maximum rating is 50 psi, but typical operating pressure is lower.

Correct pressure balances ride comfort, traction, and durability. Regular checks are important, especially with temperature changes.
