Are Hoosier A7 street legal?
NOT FOR HIGHWAY USE: All Hoosier Racing Tires including DOT labeled Hoosier Racing Tires are designed for competition purposes only on specified racing surfaces and are not to be operated on public roadways. Tire Temperature Recommendations for Hoosier Tires Optimal performance requires attention to tire temperature, which varies by track and model. Generally, peak traction occurs when pit lane temperatures reach 180-200°F (80-95°C) for R7 models used in road racing and 110-140°F (45-60°C) for A7 models in autocross.Traditionally, Hoosier tires have often required higher pressures than other brands. Hoosier recommends a starting minimum cold pressure of 26 psi on all DOT radials. LBS. LBS.Always store Hoosier Racing Tires indoors at temperatures above 32° F. If tires have been subject to 32° F or less, allow them to warm to room temperature (about 70° F) for a minimum of 24 hrs before tire is mounted, transported or flexed.The Hoosier tires typically offer better performance with spring/shock rates higher than previous brands you may have run.

Are Hoosier DR2 street legal?
NOT FOR HIGHWAY USE: All Hoosier Racing Tires including DOT labeled Hoosier Racing Tires are designed for racing purposes only on specified racing surfaces and are not to be operated on public roadways. The Hoosier Pro Street tire was designed for public highway use. They are not to be used in racing applications.Racing slicks are a marvel of tire engineering, designed for peak performance under extreme track conditions. However, their limited temperature range, lack of tread, rapid wear, and legal restrictions make them unsuitable—and unsafe—for public road use.Hoosier makes tires aimed at both amateurs and professionals competing in a variety of disciplines including stock car racing, road racing, dirt track racing, drag racing, rallying, and more.
Are slick tires street-legal?
Slick tyres are designed with the sole purpose of optimising performance on a racing track. If you use slick tyres on their vehicles and drive on a public road will be subject to legal penalties. Slick tyres have no tread and so do not grip the road in the same way as a standard road legal tyre would. The smooth surface minimizes friction between the tire and the road, translating to higher speeds and less effort required to maintain those speeds. Slick tires offer a more aerodynamic profile compared to their treaded counterparts, helping to reduce air drag and further enhancing speed and efficiency.By eliminating any grooves cut into the tread, such tyres provide the largest possible contact patch to the road, and maximize dry traction for any given tyre dimension. Slick tyres are used on race tracks and in road racing, where acceleration, steering and braking require maximum traction from each wheel.NASCAR tires are smoother than the tires on everyday vehicles. This allows more surface area on the tire to be in contact with the track. This smooth surface area provides greater grip at higher speeds, keeping racecars safe on the track.Mark Young Racing tire material is much softer than street tires. The soft material is what allows them to grip the track so well. To make the tires last longer they would need to use harder rubber making them have less grip and making them less safe.
Who makes Hoosier tires?
Continental Tire produces most motorsport–related tires at the Plymouth, Indiana, tire plant, carrying the Hoosier, Continental, and General Tire tire brands. Hoosier employs nearly 500 people, and has provided tires for use in series sanctioned by IHRA, NHRA, ARCA, CRA, NASCAR, IMCA, WISSOTA, SCCA, NASA, AIS, USAC, World of Outlaws, Lucas Oil Late Model Dirt Series and FIA World Rallycross Championship.
Why doesn’t NASCAR use Hoosier tires?
Comments Section Hoosier has said before that they don’t have the capacity to be NASCAR’s sole tire supplier. They don’t even have the capacity to make legend car tires. Getting dirt tires has been impossible for the last three years. After the race, the spent tires are either sent for recycling or held back for analysis. The tires are recycled through NASCAR’s official tire recycler, Liberty Tire Recycling. They recycle up to 120,000 Goodyear tires annually from just NASCAR’s top three national series.NASCAR purchases the tires and then makes the teams pay them for the tires at a profit. At one time the teams purchased them from Goodyear and they were able to give un-used tires back and didn’t have to pay for those. Now they do and NASCAR takes all the un-used tires.
Why are tires called slicks?
These high-durability tires are also known as “slicks,” which is a representation of the smooth tire surface and the lack of tread. There are four types of radial tires Goodyear produces — speedway, intermediate, road course and short track. Slicks will propel you to a faster quarter-mile time in most cases, especially if you have the horsepower that requires them. On the other hand, drag radials feel safer at higher speeds and give you the flexibility to drive on the street if necessary.Using drag slicks for daily use is not recommended due to their lack of tread and decreased durability and protection from punctures and blow-outs. However, drag radials are a safer option for street use, providing increased grip and traction without sacrificing durability.General Performance. On the drag strip, drag radials and slicks perform roughly the same at lower speeds. However, drag racing slicks can take better advantage of higher horsepower and torque levels. The slick’s sidewalls twist in response to torque applied by the transmission.When it comes to durability, drag radials win every time, unless you’re driving on the street every day. While slicks can last you several runs on the track, they’re more prone to punctures and blowouts.
