From the EFI conversion kit you choose to the design you add to your car, creating a racing car is a unique and rewarding experience. Choosing the right parts to build the car you dream of requires knowledge, dedication, and the willingness to go the extra mile. One of the most important aspects of the car is the tires. If you’re a first-timer, understanding the components of upgrading to racing tires is essential.
The Right Amount of Rubber
Your drag racing wheels need to be the right size. This means understanding what the numbers on your tires mean. Consider the current generation of Honda Civic sedans. The smallest tire available on them has markings of 215/55R16 93H. The first number is the width of the tire from one sidewall to the other. In this case, the width is 215 millimeters. The second number (in this case, 55) is the aspect ratio which means the sidewall contains 55% of the section width. The “R” indicates the tires have radial construction designed to fit 16-inch wheels. Finally, the 93H represents the load index and the speed rating. The load index is how much weight the tire can support while the “H” is its speed rating (130mph in this case).
Choosing the right tire size is vital. If you increase the diameter of the tires on a car, you must be sure the change in size won’t cause them to create issues such as rubbing on the wheel wells. Additionally, if you choose tires that add too much height to the car, you lose some of your ability to accelerate. Keep in mind that wider tires don’t always mean better grip on the pavement. When you’re drag racing, your tires should have larger sidewalls that provide flexibility under hard acceleration.
The Right Amount of Tire Traction
Traction is what happens when your tires meet the pavement. It allows your car to move forward. The tire compound and tire tread are the two main components that affect traction. While tires on street cars have different tread patterns to ensure they’re safe on a variety of surfaces, race tires do not have any tread patterns. This creates a slicker surface that maximizes the contact patch with the ground. They are also made of softer rubber. Softer tires with no tread patterns get stickier in heat and typically need a wheel spin before a race starts. Keep in mind that these tires are nearly impossible to use when the weather is wet, so it’s a good idea to keep a set of aftermarket wheels and your choice of tires that you can swap onto the car as needed.
Considering Drag Radials
Drag radials are tires made from a soft compound that provides as much traction as possible when driving in a straight line. Because they have a smaller tread depth and thicker sidewall, these tires are more stable and maintain their structure for longer at high speeds. Unfortunately, drag radials aren’t good for street use, so if you don’t want to deal with swapping wheels between street driving and drag racing, consider purchasing DOT-approved drag radials.
Whether you’re purchasing new racing tires or looking for Jeep accessories, always do business with reputable auto parts dealers. This ensures your safety, your car’s integrity, and that you get the most for your money.
