WHY DONT NASCAR TIRES HAVE TREAD

The reason NASCAR tires don’t have tread is simple: grip. The tires you find on street cars have tread to provide grip in wet conditions. The tread channels water away from the tire’s contact patch. In fact, NASCAR indeed has a rain tire that is used for the Nationwide Series. If our dry-weather tires (also known as “slicks”) were to have tread it would remove rubber that could otherwise be making contact with the asphalt and provide more grip. Some racing series, such as short-track divisions and Formula 1 purposefully add tread or grooves to their tires to slow cars down in the turns.

If it didn’t rain, your tires wouldn’t have grip either. That’s why it’s very important to keep an eye on the tread-depths and tire wear on your street-car. If you were to hit a wet patch with no tread it could spell disaster

Post race inspection rules change

2/2011
Post race inspection rules change a tad: In 2011, NASCAR will have two random teams selected for post-race inspection, John Darby, Cup series director explained. Last year, NASCAR took the first car out as a random for post-race inspection. That's why you saw cars go to the garage early and go back out at different times in the race to not be the first car out. Darby said that NASCAR is changing how that random will be selected. "There will still be a random inspection from the cars outside the top 35 (in car owner points), but we're going to make it more random,'' Darby said. "We're going to do it very similar to the way we do the (random) for the big group of the cars at the end of the race, drawing a number kind of situation so nobody really knows who that random will be.'' What will happen is that the crew chief of the first car out of the race will be asked by NASCAR to select two numbers. One will represent a car not in the top 35 in car owner points to be selected for post-race inspection. Another number will represent a car in the top 35 in car owner points for post-race inspection

NASCAR 2011 CHANGES

(Jan. 26, 2011) — NASCAR announced Wednesday that it has added a wild card element to setting the Chase for the NASCAR Sprint Cup field and it has simplified its points system for 2011, making it easier for fans, competitors and the industry to understand.


While the 12-driver Chase field remains intact, the final two spots will be determined by the number of wins during the first 26 races.

The top 10 in points following Race No. 26 – the “cutoff” race – continue to earn Chase berths.

Positions 11 and 12 are “wild card” qualifiers and will go to non-top-10-ranked drivers with the most wins, as long as they’re ranked in the top 20 in points. The top-10 Chase drivers will continue to be seeded based on wins during the first 26 races, with each win worth three bonus points. The wild card drivers will not receive bonus points for wins and will be seeded 11th and 12th, respectively. It’s a move aimed towards rewarding winning and consistency during the regular season.

Brian France, NASCAR Chairman and Chief Executive Officer, made the announcements at the NASCAR Hall of Fame during NASCAR’s annual media event as part of the NASCAR Sprint Media Tour.

The fans tell us that winning matters the most with them, so we’re combining the tradition of consistency in our sport with the excitement that comes along with winning,” said France. “This makes every race count leading into the 26th race of the season at Richmond, when we set the field for the Chase for the NASCAR Sprint Cup.”

The new points system – which applies to all NASCAR national series – will award points in one-point increments. As an example, in the NASCAR Sprint Cup Series, race winners will earn 43 points, plus three bonus points for the win. Winners also can earn an extra point for leading a lap and leading the most laps, bringing their total to a possible maximum of 48 points.

All other drivers in a finishing order will be separated by one-point increments. A second-place finisher will earn 42 points, a third-place driver 41 points, and so on. A last-place finisher – 43rd place – earns one point. In the NASCAR Camping World Truck Series, the last-place finisher receives eight points, to account for that series’ 36-driver race field.

“Many of our most loyal fans don’t fully understand the points system we have used to date,” said France, referencing the system that has been in use since 1975. “So, we are simplifying the points system to one that is much easier to understand. Conceptually, it is comparable to our previous system, but it is easier to follow.”

During his remarks Wednesday night, France reflected on the outstanding competition the sport enjoyed in 2010 and expected to see that high-caliber of racing to continue once the green flag drops for the 53rd running of the Daytona 500 Feb. 20.

“NASCAR enters 2011 with positive momentum and a great sense of excitement and optimism,” said France. “We’re extremely excited for the launch of the season. Leading the season off with Daytona, Phoenix and Las Vegas, we believe our fans are in store for some of the best racing the sport has to offer.”

2011 NASCAR RULE CHANGES

Pick a Series – Drivers in all three national series now must select the series where they’ll compete for a driver championship. Drivers still may compete in multiple series and help their teams win owner titles in series where they’re not competing for a driver title. The move helps spotlight young talent in the NASCAR Nationwide and NASCAR Camping World Truck Series.
New Qualifying Procedure – The qualifying order will be set based upon slowest to fastest practice speeds.

Inclement Weather Qualifying – If bad weather cancels qualifying, the final starting lineup will be determined by practice speeds. The same rule book procedures will be used to determine eligibility to start a race. If weather cancels practice sessions, then the starting lineup will be set by points, per the rule book.

Tire Rules Revision – NASCAR Sprint Cup Series teams now are allowed five sets of tires for practice and qualifying instead of six. They must return four of those sets to Goodyear in order to receive their race allotment, and may keep one set of practice/qualifying tires. Tire allotments for race weekends will vary according to historical performance data.

Closed Loop Fueling System – Introduced in the NASCAR Camping World Truck Series, this goes into effect for all three national series in 2011.
It combines a more efficient fueling system with the elimination of the catch-can man, considered the most “vulnerable” pit-crew member. Teams now will use six, rather than seven, over-the-wall pit-crew members.

Evolution Of NASCAR Sprint Cup Series Car – NASCAR continues to work with the manufacturers and teams to enhance the look of the NASCAR Sprint Cup Series car. The cars have new fronts this season and the body makeover will continue to help appeal to fans and aid manufacturer identity.
