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
The M&H Racemaster 8.5/24.5-15 Drag Slick is specifically described as a popular choice for many front wheel drive import drag racing applications. Its HB11 medium compound is engineered to deliver strong traction during launches while maintaining predictable behavior throughout a drag strip pass.
Fitment still depends on your vehicle's available clearance, suspension setup, and wheel specifications. Before purchasing, measure the available space around the wheel wells, suspension components, and struts to verify that the tire's approximate dimensions fit your combination. Small differences in ride height or wheel offset can influence final clearance during acceleration.
The M&H Racemaster 8.5/24.5-15 Drag Slick is identified as a Track Use Only tire and is not DOT certified for public road use. It is engineered to maximize straight-line traction on prepared racing surfaces rather than provide the durability, wet weather capability, or tread design expected for everyday driving.
Because the tire is a true slick without tread grooves, it offers very limited water evacuation and is unsuitable for normal highway conditions. Owners planning to drive on public roads should use an appropriate street-legal tire and reserve this drag slick exclusively for racing events and controlled track environments.
Before ordering the M&H Racemaster 8.5/24.5-15 Drag Slick, confirm your wheel diameter, rim width, available suspension clearance, and intended racing application. The product is designed for track use and performs best when installed according to the recommended specifications listed for the tire.
It is also helpful to compare your current tire dimensions with the new size to understand any changes in gearing, stance, or speedometer readings. Checking inflation recommendations, wheel condition, and available space around brakes and suspension components before installation contributes to a smoother setup and more consistent drag racing performance.
Tire Size Equivalents & Conversions â–¼
Any change in overall tire diameter has the potential to influence speedometer readings. If the M&H Racemaster 8.5/24.5-15 Drag Slick replaces a tire with a noticeably different diameter, the speedometer may display a speed that differs from the vehicle's actual travel speed.
Although many dedicated drag racing vehicles rely on racing electronics rather than factory speedometers, the difference can still matter when comparing setups or using a street-based platform for racing. Comparing the old and new tire diameters before installation provides a better understanding of any expected changes.
Performance & Use Case â–¼
The M&H Racemaster 8.5/24.5-15 Drag Slick uses a treadless slick design that maximizes the amount of rubber contacting the racing surface. Combined with its bias ply construction and HB11 compound, this design helps generate the grip needed for hard launches on properly prepared drag strips.
Traction also depends on vehicle setup, burnout procedure, suspension tuning, and inflation pressure. Even a high-performance drag slick performs best when these supporting factors are properly adjusted. Careful preparation before each run allows the tire to deliver more predictable and repeatable launch performance.
The M&H Racemaster 8.5/24.5-15 Drag Slick is engineered for straight-line acceleration rather than sustained high-speed highway driving. Its bias ply construction supports drag racing applications by providing the flexibility needed during launches while maintaining stability throughout a drag strip pass.
Drivers may notice that bias ply drag slicks respond differently from modern radial performance tires because of their construction characteristics. The tire is optimized for controlled racing environments where consistent acceleration is more important than long-distance cruising or repeated high-speed highway operation.
Construction, Durability & Load Capacity â–¼
The M&H Racemaster 8.5/24.5-15 Drag Slick uses bias ply construction, where the tire plies overlap in a crisscross pattern at approximately 45-degree angles. This design provides the sidewall flexibility valued in drag racing, allowing the tire to absorb launch forces and maximize traction on a prepared racing surface.
Bias ply tires have different handling characteristics than radial tires, particularly during acceleration and at speed. While they excel in straight-line performance, they are designed specifically for drag racing rather than everyday road use. Buyers seeking authentic drag racing behavior will appreciate the characteristics that bias ply construction offers.
The M&H Racemaster 8.5/24.5-15 Drag Slick is engineered for repeated use in drag racing environments when properly maintained. Its medium HB11 compound balances traction with durability, making it suitable for racers who participate in frequent test-and-tune sessions or competitive events.
Tire life depends on several factors, including burnout technique, vehicle weight, horsepower, track preparation, and inflation pressure. Regular inspections between runs help identify uneven wear or damage before it affects performance. Proper storage and maintenance also contribute to preserving the tire's performance characteristics over time.
Proper storage helps maintain the condition of the M&H Racemaster 8.5/24.5-15 Drag Slick when it is not being used. Keeping the tire in a cool, dry location away from direct sunlight, ozone-producing equipment, and prolonged exposure to extreme temperatures helps preserve the rubber compound.
Cleaning the tire after racing removes debris that could affect future performance. Racers should also inspect the sidewalls and tread surface before storing the tire so any signs of wear or damage can be addressed before the next event, reducing the chance of unexpected issues at the track.
Installation & Maintenance â–¼
Inspecting the M&H Racemaster 8.5/24.5-15 Drag Slick after each racing session is a good maintenance practice. Look for cuts, abrasions, punctures, sidewall damage, or unusual wear patterns that may indicate changes in suspension alignment or contact with nearby vehicle components.
Routine inspections also allow racers to detect issues before they become more serious. Identifying small problems early can help prevent unexpected failures during future events and contributes to more consistent performance throughout the racing season.
Maximizing the life of the M&H Racemaster 8.5/24.5-15 Drag Slick begins with proper storage, regular inspections, and maintaining correct inflation pressure. Keeping the tire clean and protected from prolonged sunlight and excessive heat helps preserve the rubber compound between racing events.
Consistent burnout techniques and careful monitoring of tire condition also contribute to more predictable wear. Avoiding unnecessary abuse outside of normal racing use allows the tire to maintain its intended performance characteristics over a longer period of competitive use.
