Hoosier Quick Time DOT Drag Radial 2
Developed for drag racers, the Hoosier Quick Time DOT Drag Radial 2 delivers an improved tread profile to ensure best performance results. The drag radial has less rolling resistance than bias ply racing tires, and they are ideal for competition class races that require street legal tires. In 15”, 16”, and 17” diameters, these Hoosier Quick Time radials are designed to add speed to your drag run. Hoosier designed the Quick Time DOT Drag Radial 2 for clean hook ins and took side to side tire swaps to the next level with symmetric tread design and an internal construction that allows them to be installed on either side of the car without any tire wear issues.
At A Glance Features:
- Beginning at 4/32” molded tread depth, they are realistically manufactured to scuff in and ride.
- Sturdy sidewall construction for a smooth ride and stabilized cornering
- Special tread compound that is molded to slick tread design with five dash circumferentially oriented grooves
- Symmetric nylon cord casing, reinforced by lightweight belts and spirally wrapped nylon reinforcement under the tread
- Great for hooking in, leading to a clean, efficient and quick run
- Improved tread profile over the first design to deliver best performance.
- The Hoosier Quick Time DOT Drag Radials 2 offer the ability to handle and hook up without issue on the track
- Minimizes the amount of rubber throwback onto your quarter panels because the tread is 4/32” start depth
- Solid white lettering adds a clean finish to this solid radial tire. Conversely, blackwall finish is featured on the opposite side.
- Five dash circumferentially oriented grooves alternating outboard and inboard on this improved design
- These tires are not legal for highway applications, and are for sanctioned race applications only. However, the R6 and A6 series of Hoosier DOT Drag Radials are the approved road racing radials, and these are available in the same size selections as the non highway approved radials.
- A concern with some racers has been with the stiffer sidewall in regards to the ability to hook and handle as well as some other radial designs. However, it has been shown in track applications that the stiffer sidewall has allowed for a lower tire pressure without decreased accuracy or the issue of sidewall rollover occuring.
Hoosier DOT Drag Radials 2 are manufactured to have a softer and more pliant overall feel than some of the competitors radials. A key feature that is applauded is the ability to scuff in the tire, versus extended burnouts to season the radial. This is designed by Hoosier to preserve the tire tread.
Weighing in much lighter than the radials offered by the competition, the Hoosier Quick Time DOT Drag Radials 2 won’t rob power from your launch by unnecessarily weighing your car down. In addition, with the smaller diameter giving more power at higher revolutions, you’ll see less overall vehicle drag while maintaining grip.
The Hoosier Quick Time DOT Drag Radials 2 have a larger contact patch to prevent spinning, and a sturdy sidewall will ensure a smooth ride, transferring less shock to the drive train. In 15” through 18” wheel diameters, the Hoosier company has created a versatile radial that can be a choice product for models ranging from Corvette to the Mustang Shelby. However, they may need to be trial run to check for potential ABS sensor issues due to the overall diameter of the radial.
The symmetric nylon cord casing and five dash circumferentially oriented grooves that alternate outboard and inboard ensure connection with the track. Dead hooks and precision handling are not a problem with this radial, and the lighter overall tire, you won’t find yourself sacrificing stability for speed. The 4/32’s beginning tread depth aid in reduced rubber throwback onto quarter panels. Five dash circumferentially oriented grooves alternate between outboard and inboard.
Seasoning these radials is best performed by three to eight track passes to remove the directional patterns. Performing extended burnouts on the Hoosier DOT Drag Radial 2 is not necessary or recommended. These radials are designed to simply scuff in and race. The Hoosier DOT Drag Radials are designed to be rotated on each side of the vehicle after each drag event in order to keep the wear patterns even and ensure peak performance. Side to side tire swapping allows the tires to run in both directions, as it will cause the tire to wear differently and help to clean up the tread.
DOT Labeled Hoosier Racing Tires meet DOT requirements for marking and performance only. They feature a special compound to provide good traction, making them perfect for classes that require street legal style tires. The drag radial compound is key to track performance because the tire compound gets gummy once it is heated. Bringing the compound to the surface increases the tires stickiness to improve tire grip and help your vehicle stay on the track. The Hoosier DOT Drag Radials are not intended for street use or for use on public roads.
In the case of all racing radials, to store these tires you need to release the air pressure and store indoors in a cool, dark room. It is also best if you lay them on their side to store them.
Hoosier DR2 Drag Radial Sizes
The Hoosier DR2 drag radial comes in a variety of common sizes designed to fit everything from all out drag cars to high performance street cars on 18″ wheels. You can find the DR2 drag radial in the following sizes:
15″ Hoosier DR2 Drag Radial
Nitto NT555R 275/50R15
- Weight: 25 lbs
- Diameter: 25.71″
- Width: 11.10″
- Approved Wheel: 7.5″ – 8.5″ – 9.5″
Hoosier DR2 Air Pressure
After mounting and balancing your new 555R’s, it is recommended to start with a cold tire inflation of around 20 psi. Based on this, adjust the tire pressure 1 psi until you achieve your desired results.
As always, it is best to use the highest tire pressure you can without any tire spin. This will help with tire stability and reduce rolling resistance.
However, when using on the street, it is always recommended to inflate the tires more than you would normally for the track. Just be aware that too much air pressure in the 555R’s will cause uneven wear and cause the centers to wear out faster than the rest of the tire.
With personal experience using the 555R, we find that they hook well on the street with about 22-24 PSI. We haven’t taken these tires to the track yet, but are certainly excited to test them out.
Hoosier DR2 Reviews
For some time the Nitto NT555R has been one of the top selling drag radials, and rightfully so. With its lower price point, increased grip, and suitable wet traction, the 555R is a great option for the average weekend muscle car hobbyist.
