Will Tire Limits Improve Racing?
Will 2017 Tire Limit Rules Require Harder Tires? Back in the day, the only thing that limited how many sets of tires you could use in Cup-level racing was your budget. It was different in the lower level series, because Cup teams that also ran XFINITY (for example) had much […]
The Goodyear Blimp… Technically Isn’t
I’ve started work on a new book about how rapidly we’re learning to integrate robotics with human beings. It won’t be too long before we have real-life cyborgs. One of the most surprising things I’ve learned in researching the book is the huge role the military plays in developing advanced prosthetics — which might […]
How Tracks Take and Lose Rubber
The two words we heard most frequently last week in Pocono (after “still raining”) were “green racetrack”. Rain doesn’t just delay racing. When the race is finally run after a rain delay, it’s run on a different racetrack. To get the details of how a racetrack changes from “rubbered up” […]
NASCAR is very clear about what teams can and can not do to the tires. Teams may not use any chemical or physical means of altering the tires, which means no siping (cutting grooves into the tires), no chemical softening, not even heat blankets to pre-warm the tires are allowed. Basically, you can’t do anything to the tires. This means that when a tire blows out, it’s the tire’s fault. Right?
Do Tires Affect Gas Mileage?
When winning means a few hundredths of a second, nothing is too small to be ignored. I’ve talked a lot about energy and the importance of using it as efficiently as possible in racing. Gasoline provides a certain amount of stored (a.k.a. potential) energy. Everyone gets the same amount of energy. Winning lies […]
Required vs. Recommended Tire Pressures
Running on underinflated tires can be dangerous. Underinflated tires they create more friction and more heat, which leads to not only bad handling, but also can produce structural problems.
The Dirt on Radials vs. Bias-Ply Tires
ne of my favorite memories from Nebraska was coming home from the I-80 Speedway covered in a dusting of red clay. (Planting in that clay was another question entirely.) But there’s something about dirt tracks that you just don’t get at the asphalt ones.
The Kansas Monozone Tire
OK, so ‘monozone’ is just a fancy way of saying it’s the old tire. It’s all in the branding, isn’t it? Goodyear has been experimenting with multi-zone tires since last year. Multizone tires attempt to get the best of both worlds by combining a harder compound on the inner 2-3 […]
Camber Angle and Tire Wear
We’ve heard a lot, especially this week at Richmond, about tire wear. A lot of right front tires were wearing excessively. As seems to be usual at this point, teams would like Goodyear to use a stronger tire and Goodyear would like teams to dial back their setups, especially their camber.
Tires and the COT
You all know Newton’s first law of motion (NASCAR version). A race car going 130 mph down the frontstretch at Bristol is going to keep going 130 mph down the frontstretch at Bristol unless a force makes it do something different In more science-y words, you can’t (thanks Josh) turn […]
