For the Daytona 500 NASCAR teams are allowed up to 8 sets of tires for practice and qualifying as well as additional 7 sets (one set carries over from practice) for the actual race itself. In total, 15 sets of tires are allowed, or 60 individual tires. The actual amount of tires used in the race will vary depending on the driver and team, but ...
In 2015, tires cost $493 each . That's almost $24,000-worth of rubber for a weekend requiring 12 sets. It's good to be one of those well-funded teams.
Answer (1 of 2): Adding or removing tire pressure alters how the tire responds to steering input. It is carefully tracked and altered depending on many variables such as track temperature, air temperature, track surface, driver preference and others. It’s a …

Somewhere in the range of 26psi to 32psi is usually about right for rough gravel. If you were running 38psi on the road, then drop pressures to 32psi on rough gravel and see how it feels. If you were running 30psi on the road then 26psi might be appropriate on crook gravel roads and tracks.Feb 19, 2018
The short answer is that Formula 1 holds races in the rain because cars can drive in rainy conditions. The cars themselves are essentially water-resistant, so they can survive a downpour, and the wet weather tires (discussed in the next section) enable cars to drive in the rain safely.
NASCAR tires have a completely smooth tread. These tires are designed to have as much contact on the track as possible.Dec 22, 2008
Higher pressure generally is not dangerous, as long as you stay well below the “maximum inflation pressure.” That number is listed on each sidewall, and is much higher than your “recommended tire pressure” of 33 psi, Gary. So, in your case, I'd recommend that you put 35 or 36 psi in the tires and just leave it there.
For a 35" you should be in the 28-32 range on road.Aug 23, 2018
Hop in the 4x4, and drive for more than half an hour and check them again. There's a pretty good chance that they will now read somewhere between 38 and 42 PSI, and that's completely normal. The lower your pressures and the more the tyre flexes, the more the tyre pressures will change.Aug 20, 2019
The Daytona 500 is usually regarded as the most important race of the NASCAR cup series and is held at the beginning of each NASCAR season. Unlike other sports where the championship is held at the end of the season, the Daytona 500 kicks off the season in a wave of excitement.
Before Goodyear became the exclusive supplier of NASCAR in 1997, two other manufacturers were also producing tires for the sport. The Firestone Tire and Rubber Company and the McCreary Tire and Rubber Company were Goodyear's primary competitors in the beginning, but after beating at those two companies Goodyear had its toughest battle with Hoosier.
The tires used by NASCAR are designed to handle the high speeds of racing and each tire can only last for about 100 miles of racing. The tires are designed to have as much grip as possible, especially when the rubber heats up to increase the traction and control for the driver.
All NASCAR tires are currently manufactured by the company Goodyear, which is based in the United States and focuses on tire production for all types of vehicles. Since Daytona's race lap is longer than 1 mile, NASCAR requires all cars to have inner tires and the PSI of the inner tires should be 12-25 more PSI than the outer tires.
Depending on the race, NASCAR then sets a cap on how many additional sets of tires teams can have for each event. This number can range anywhere from five sets for shorter races to 14 sets for longer races, but not every team buys the maximum amount of sets allowed. "Most of the major teams do get their full allotment," Stucker says. "Some of the small teams and teams that aren't as well funded obviously don't get as many."
The much larger traction zone on the outside of the tire has a grippier tread to maintain traction. NASCAR regulations also mandate that on any track longer than one mile tires must have a tubeless inner tire that attaches separately to the wheel and has its own nitrogen supply.
At the track, the tires get mounted on their wheels and balanced by Good year employees known as tire busters. Each team then inspects the tires to create four-tire sets of left and right tires that will provide the best performance for the car. Because tires can still come off the line slightly different, tire specialists will look to make sure a set has the same tire pressure or chemical compound, which is provided on a barcode tag Goodyear places on each tire. "They'll measure the entire circumference of the tires," Copp says. "They'll measure how hard the rubber compact patch is. There are holes, five small wear holes that are more like indents that run left to right across the entire, they will measure those with a depth gauge and document each and every one of these holes for each and every single one of these tires."
And for some tracks, including Richmond International Speedway, Homestead-Miami Speedway, and Texas Motor Speedways, Goodyear uses two different compounds on the same tire, called a multi-zone tread. The portion of the tire's inner side is the endurance zone and features a firmer compound to help prevent wear.
For road courses, teams use the same tires on all four corners because the car will be turning left and right. But for any sort of oval track with banking, the right side tires are an inch wider—called staggering—and are made of a different compound.
The leasing program started in 2006 when NASCAR wanted to impose limits on testing. At the time, teams with more money were getting an advantage over poorer teams by testing out extra tires on tracks before races. NASCAR asked Goodyear, the exclusive provider of tires for the Sprint Cup Series, if it could track the inventory better ...
This is now less of an issue since NASCAR has implemented testing guidelines, so teams no longer have to return their wheels to Goodyear, says Greg Stucker, Goodyear's director of racing. "We still know which tires go to what team," he says.
Liberty Tire, the official tire recycler of NASCAR Green, ensures each tire used in NASCAR competition is not only handled properly and recycled, but also makes sure it is turned into something extremely useful.
Through barcodes, Liberty Tire is able to track each tire ‘from cradle to grave.’. Throughout the course of a year, Liberty Tire recycles roughly 300,000 tires between the Sprint Cup, XFINITY, Camping World Truck Series and the NASCAR Home Tracks.
Another use of the recycled tires is to create rubberized mulch. Under this process, the steel is removed from the tire through a grinding and magnetic process.
Thanks to the rubber mixture, the pavement also drains water more efficiently, making it easier to dry the surface quicker. The rubberized pavement also typically lasts two times longer than traditional asphalt, which means it cuts down on the amount of repaving that is needed over the course of time.
As I mentioned, most vehicles will recommend a tire pressure of between 30-36 psi. So as we can see, there is a recommended PSI for every vehicle. But what happens if the tire pressure is to low or the tire pressure is too high. Let’s take a look.
You can find the recommended PSI there as well. Now, if you look at the sidewall of your tire, it may say that the maximum tire pressure for your tire is 60 PSI (pounds per square inch), and you may think AWESOME!
To avoid all of this, check your tires regularly. At least once a month. Use a tire pressure gauge and not your TPMS light as a guide.
How do you check the Air Pressure in your tires? 1 Make sure your tires are ‘cold’ or haven’t been driven on for at least three hours. Heat actually increases the air pressure inside the tire. Therefore, if you check your tires when they are ‘hot’, you will not get an accurate reading. 2 Unscrew the valve stem cap and apply the tire gauge to the valve stem 3 You will hear a little bit of air escaping the tire, that’s okay. It should only take a second for your tire gauge to measure the air pressure. Don’t hold the tire gauge on the valve stem for too long or you will start to release a significant amount of air from the tire. 4 Compare that number to the one on the inside of door jamb 5 If the tire pressure matches your vehicles recommended tire pressure you are good to go; if not, get somewhere you can add air to your tires. 6 You’re Done!
Yes, once a month, break out the tire gauge that should be in your car and do the five-minute inspection. Don’t do just one or two tires, go around to all four tires and make sure they have the proper PSI.
An overinflated tire will wear out more quickly and unevenly. Think of the middle of the tire tread, the “ top” or “bottom”, if you will; bulging out. So instead of getting even wear across the whole tire, you only have a small section of tire absorbing the wear and tear of travel.
Your tires are your first and best line of defense for safe driving. Take the time to make sure they are well cared for. Whether it is your everyday commute or you are getting ready for a long road trip; your tires are carrying you there. Take care of them.
Since tires are the only link between the track surface and the car, they are critically important. And how the team and especially the driver manage those important components is major key to success. The original idea behind “tire management” related to how the driver cared for the tires and manipulated the tires for maximum traction.
Cleaning may be the more important of the two criteria, because abrupt steering inputs will put heat in the tires also, just not as quickly as hard braking and acceleration.
This gives the tires a good chance to get up to temperature. Most tires are at optimum traction when temperatures at the contact patch are between 160 degree and 220 degrees Fahrenheit.
Tire Management – How to Get the Most out of Your Race Tires From Behind the Wheel. In the mid-1990s, the term tire management became a common phrase made popular by commentators on NASCAR television broadcasts. The term was first used in a Circle Track magazine article as part of a series I wrote while serving as the magazine’s editor.
Using any control too abruptly can cause problems. The more abrupt, the bigger the problem becomes. Too hard and fast on the throttle can induce wheel-spin, especially exiting slow corners in a front driver. Wheel-spin causes a reduction in traction, overheats the tires and accelerates tread wear.
Since traction is proportional to vertical load on a tire, when weight transfers onto a tire and off another tire, the relative traction changes.
Braking and turning puts more weight on the outside front tire, takes weight off the inside rear tire. Used properly, this can reduce corner entry understeer. At corner exit, the correct amount of throttle application can increase drive off a turn, reduce oversteer or increase understeer.
If you do not know what PSI stands for a PSI reading is used to indicate how much air is currently in the tire. The higher the pounds per square inch the more air is present inside of the tire and the stiffer the tire will be. The lower the PSI reading the less air is in the tire and the softer the tire will be.
The easiest and quickest way to find out what tire pressures are recommended for your car is to look in the driver’s door sill after opening your door . On the majority of vehicles, you will find a sticker indicating what the front tire pressure should be along with what PSI the back tires should be inflated to.
If you inflate your tires over what is recommended this will usually result in a rougher ride as the sidewall of your tires will be stiffer.
If you don’t inflate your tires all the way to the recommended tire pressure then this will result in you getting worse gas mileage because the contact surface of the tires will be increased by the deflated tires.
If you don’t have access to a free air pump at your local gas station the best way to keep your car tires inflated is by buying a portable tire pump. With this a portable tire air pump you can air up your tires from virtually anywhere as long as you still have power to your car. Most portable tire pumps will be able to be plugged ...
The lower the PSI reading the less air is in the tire and the softer the tire will be. Each car is different and vehicle manufacturers will recommend different PSI ratings depending on the type of vehicle. So how do you find the correct PSI or tire pressure for your specific vehicle.
The theory behind this is that the front of your car is likely heavier (unless you have a car with the engine in the back) because the engine is over the front wheels. The other factor for different PSI ratings between front ...
