Hard Tire Class Rules: ALL DOT TIRES MUST BE A MINIMUM TREAD-WEAR RATING OF 220! -Tires must have the tread wear rating on the size wall and be a DOT approved tire. no minimum or max tire size but recommend using a 275/60R15 tire. -FWD and RWD vehicles only.
What is hard tire?
A hard sidewall means that the sidewall has been manufactured to be harder and is less likely to flex, while a soft sidewall is designed to be more flexible. Tires that are designed to be harder will have a thicker sidewall than tires designed to be soft.
What does it mean in racing to knock the tires off?
When a car loses traction; also “blew the tires off” or “hazed the tires.”
What is considered a big tire in street racing?
A big tire car as defined by this competition is any tire larger than a 10.5W. Big tires give you the advantage of great traction, but with the penalty of all the weighty rubber and rolling resistance. Racers making 3,500 hp on methanol in a 2,500 pound car like these guys are, just don’t care.

What tires do street outlaws use?
We listened and worked with Mickey Thompson Tires to make it happen for this year.” The category offers compelling competition with supercharged, turbocharged, and nitrous-enhanced entries that run deep into the 4-second zone on a pair of 275/60R15 radial tires.
Are thicker tires faster?
Yes. This is because, at the equal pressure, the casing tension of the wider tyre is higher and the contact patch is shorter and wider. The first of these factors means less energy is lost to casing flex, and the second reduces rolling resistance because the shorter, wider contact patch reduces frictional losses.
What wheel size is best for street racing?
The best practice is to go with a smaller wheel for performance and as much tire as you can fit to get the most traction possible. On average, you will see the best results with wheels for the front that are in the 15×3.75-inch range or larger, and in the rear a set of wheels in the 15×10-inch range is ideal.
What size tire do street outlaws run?
Quick Fact:Not to be confused with NMCA’s Super Street class, which requires its racers to run on a 10.5W tire (measuring around 11.2 inches), the NMRA Super Street Outlaw class is required to put as much as 1,800 hp to the ground with real 10.5-inch tires as measured.
What size tires are good for racing?
For decades, F1 cars have run on 13-inch wheels, wrapped in tires with high-profile sidewalls. But as part of 2022’s radical technical shakeup, the sport is now joining much of the rest of the racing world as it adopts 18-inch wheels and new, low-profile racing rubber.
What is considered a small tire in street racing?
Up to 29″ is considered a small tire.
Do you go faster with smaller tires?
With smaller wheels you would go faster but cover a smaller distance per revolution of the wheel where as with a larger wheel you would go slower but cover a larger distance. For any fixed RPM an imaginary fixed point on the smaller wheel’s circumference will be faster as it has to cover a smaller distance.
Do small wheels accelerate faster?
Yes, smaller wheels accelerate faster, but it doesn’t matter. It all has to do with the rotational moment of inertia. The moment of inertia of an object is simply how easy it is to move the object. The heavier something is, the harder it is to move.
Whats faster bigger or smaller wheels?
Yes; provided the wheels are turning at the same RPM. You have to put proportionately more effort into turning a big wheel but it will go faster if you can keep it spinning at the same rate as a small one.
Do harder wheels go faster?
Hard Wheels:
– Harder wheels are better for speed and skating on smoother surfaces. They also tend to last longer than softer wheels. – The downside of harder wheels is that they can be more difficult to control, especially for beginners. They’re also more likely to slip on rougher surfaces.
What size tire gives the smoothest ride?
Smaller wheel = smoothest ride quality, low stability, predictable handling, average road noise. Medium wheel = average ride quality, average stability, predictable handling, low road noise.
Do thicker tires ride better?
As a general rule, bigger wheels result in a rougher ride. Switching to a smaller wheel and a thicker tire can give you a smoother ride without any major modifications to your car. However, if you go too crazy and change your wheel size too much, it can cause some problems.
How much mpg will I lose with bigger tires?
With today’s new tires, there is virtually no difference in mpg due to tire size. As with many questions related to cars and tires, the answer to this question can have nuances, conditions, and variations.
Do you go faster with bigger tires?
Larger wheel diameters can result in faster and more composed handling; however, it can also result in slower acceleration capability. While there are a few disadvantages for any vehicle when increasing the wheel and/or tire size, curb appeal usually outweighs them.
Why do I feel every bump in the road?
Feeling every bump
If you start to feel every bump on the road, it’s a clear sign that there is a problem with your shock absorbers or struts, that needs to be checked. An easy check is the bounce test. Simply push your entire weight down on your car’s bonnet. Release and count the number of times the car bounces.
Do new tires make a smoother ride?
Typically, the replacement will provide a smoother ride. It will probably also be quieter, and offer better traction on wet or snow-covered surfaces, along with better balance and uniformity.
