1100-18 STA Classic Military Blackwall Tire
The non-directional tread design on these Military NDT Tires provides equal traction in either direction and are iconic fitment on historic American military vehicles. NDT tires are used on restored military Jeeps, trucks and other historic working vehicles.
Blackwall Tire
Since the introduction of carbon black rocked the tire industry, the original recipe for most tires has been a solid black sidewall. For classics and collector cars alike, it's hard to beat the no-nonsense appeal of a classic blackwall style tire. British sports car, classic truck and even hot rod enthusiasts love the way a nice period correct blackwall tire looks on their vehicles.
Bias Ply Construction
Bias ply tire construction is a method that was used from the 1900's through the 1970's on passenger cars and light trucks. Bias ply tires feature ply cords that run at a 45 degree angle to the bead, and overlap in a crisscross pattern, depending on how many ply layers are used. This creates a strong tire, but bias ply tires have a tendency to follow breaks or ruts in the pavement. Bias ply tires are the most authentic choice for classic car restorations and traditional hot rod builds. Coker Tire offers a huge variety of bias ply tires for many applications.

Frequently Asked Questions
Fitment & Compatibility â–¼
Not necessarily. While the 1100-18 STA Classic Military Blackwall NDT Tire is designed for an 18-inch wheel diameter, wheel width and wheel design also influence proper fitment. A tire can technically mount to a wheel with the correct diameter while still producing undesirable sidewall shape, tread profile, or handling characteristics if wheel width is not appropriate.
Buyers should confirm that their wheel dimensions closely match original military specifications. A wheel that is excessively narrow or wide can alter the tire's section width, sidewall profile, and contact patch shape. These changes may affect steering response, ride quality, and overall vehicle appearance, particularly on restoration-focused vehicles.
The safest approach is to compare the tire size currently installed on your vehicle with factory specifications, military service documentation, restoration manuals, or existing fitment records. The 1100-18 STA Classic Military Blackwall NDT Tire is intended for vehicles originally designed around this specific size and overall tire package.
Replacing a tire with a significantly different diameter can affect ride height, gearing, and speedometer accuracy. Even small diameter changes can influence clearance at the fenders, steering components, and suspension travel points. Maintaining the original size helps preserve the vehicle's intended appearance and operating characteristics while minimizing unexpected fitment issues.
For buyers prioritizing historical accuracy, the 1100-18 STA Classic Military Blackwall NDT Tire closely reflects the appearance and construction associated with military vehicles of its era. The non directional tread design, blackwall styling, and bias ply construction help recreate the original look expected at military vehicle shows and restoration events.
Authenticity does involve trade-offs. Drivers should expect different ride and handling characteristics than modern radial tires provide. However, many restorers consider these characteristics part of the authentic ownership experience. Buyers seeking factory-correct appearance and period-appropriate tire construction often view this style of tire as the preferred restoration solution.
Tire Size Equivalents & Conversions â–¼
The 1100-18 STA Classic Military Blackwall NDT Tire uses a traditional military and bias ply sizing format rather than the metric sizing systems commonly found on modern vehicles. Because modern tire sizes use section width, aspect ratio, and wheel diameter measurements, direct comparisons are not always straightforward.
When considering replacements or alternative sizes, overall diameter and section width are usually more important than matching size designations alone. Buyers should focus on maintaining similar dimensions to preserve vehicle stance, clearance, gearing, and speedometer accuracy. Consulting vehicle-specific fitment references remains the safest approach when comparing older and newer tire sizing formats.
Yes. The webpage specifically notes that tire dimensions can vary based on rim width and inflation pressure. A wider wheel can stretch the tire slightly, while a narrower wheel may create a more rounded sidewall profile and alter measured section width.
These dimensional changes may seem minor but can affect clearance and appearance. Buyers working with original military wheels generally experience dimensions closest to intended specifications. When using aftermarket wheels, it is important to account for how wheel width may influence final tire measurements and overall fitment.
Performance & Use Case â–¼
The 1100-18 STA Classic Military Blackwall NDT Tire can be driven on highways, but its driving characteristics reflect vintage tire technology. Drivers may notice increased road feel and a tendency to follow pavement grooves compared with modern radial tires.
Heat buildup becomes increasingly important during extended highway travel. Proper inflation pressure and routine inspections help maintain performance and durability during longer trips. Owners who regularly operate historic military vehicles on highways should understand that the tire prioritizes period-correct construction rather than modern touring tire comfort.
The non directional tread design provides equal traction characteristics regardless of rotation direction. This design was widely used on military vehicles because it simplified maintenance and offered predictable operation across varied terrain and operating conditions.
For collectors and restorers, the tread pattern is also a major part of the tire's authentic appearance. While modern tread designs often emphasize optimized wet-road performance or noise reduction, the NDT pattern focuses on durability, versatility, and historical correctness. Buyers seeking original military aesthetics frequently consider this tread design an essential feature.
Yes. Many collectors choose the 1100-18 STA Classic Military Blackwall NDT Tire because it balances authentic appearance with real-world usability. The military-style tread pattern and blackwall sidewall help create a historically accurate presentation at shows, exhibitions, and restoration events.

These characteristics are normal for period-correct bias ply tires and are often considered part of the authentic vintage vehicle experience.
The 1100-18 STA Classic Military Blackwall NDT Tire is primarily designed to replicate the appearance, construction style, and functionality associated with historic military vehicles. Its non directional tread pattern, blackwall appearance, and bias ply design all contribute to maintaining restoration accuracy for collectors and enthusiasts.
Buyers should understand that authenticity and modern performance goals are not always the same. While the tire is fully usable for driving, its construction reflects vintage engineering priorities rather than modern ride comfort or high-speed touring expectations. Owners seeking factory-correct presentation often consider these period-specific characteristics a major advantage rather than a limitation.
Installation & Maintenance â–¼
The product page references related tube and flap components, which indicates that many military vehicle applications using this style of tire may involve tube-type wheel systems. Whether a tube is required depends on the specific wheel design and vehicle configuration being used.
Owners should verify the original wheel specifications and consult fitment requirements before installation. Using the correct tube and flap combination when required helps support reliable operation and reduces the risk of damage to internal tire components. Proper matching of all installation components is particularly important on vintage military vehicles.
Many collector and military vehicles spend extended periods in storage between events and driving seasons. During these periods, maintaining proper inflation and protecting the tires from prolonged environmental exposure can help preserve condition.
Whenever possible, store the vehicle in a cool, dry environment and inspect the tires periodically. Long-term neglect can contribute to flat spotting, pressure loss, and other age-related concerns. Consistent storage practices help maintain appearance and support reliable performance when the vehicle returns to service.
The most effective maintenance practices include maintaining proper inflation pressure, monitoring tread wear, inspecting suspension and steering components, and addressing alignment issues promptly. These habits help support consistent handling and predictable tire wear.
Owners should also inspect the tires before major events, highway trips, or extended periods of operation. Paying attention to wear patterns, ride quality changes, and pressure fluctuations can help identify developing issues early. For collectors and restoration enthusiasts, routine preventive maintenance remains one of the most important factors influencing long-term tire performance and durability.
