Fed up with all of the cars parked along the street in her quiet neighborhood, an 89-year-old grandmother in Germany started slashing their tires. Altogether some 50 tires were vandalized before a neighbor spotted and reported the nefarious nana. The granny, Heidi Kohl, eventually confessed and was fined, but the story doesn't end there. When she told authorities she wouldn't be able to pay, they decided to have her work off her debt. They instead sentenced her to hard time knitting sweaters for her victims. We don't know how sweaters work for traction, but if the German officials are satisfied who are we to question their judgment? Prosecutors added that they don't fear any further actions by the sassy senior, pointing out that she has since moved to a retirement home.





Remember in the first Crocodile Dundee movie when he gets mugged in New York City and Sue says "He's got a knife," and Dundee says, "That's not a knife, this is a knife," and then he pulls out a beast-killing monstrosity of a blade? Well, that's what the folks at Titan Tire are saying right now about every other -- smaller -- tire in the world.
Titan has made a 63-inch rubber behemoth for use on trucks in Canada's oil sands. The stats on these rubber donuts is impressive: the 59/80R63 is the biggest production tire in the world, standing over fourteen feet tall and weighing 12,500 pounds with a load rating of 101 metric tons. It makes Titan a very appropriate name for the company, as we learned from another movie, Remember the Titans, that in Greek mythology the Titans were greater even than the gods. Now we can only hope this development will make the price of oil drop another ten dollars...

The car-buying public has put its collective foot down and demanded fuel-efficient vehicles, and automakers are likely to do anything to answer customer demand. That may include reinventing the wheel, as more automakers look into incorporating low rolling resistance tires into non-hybrid vehicles. The high-pressure rubber can return fuel economy improvements of 1-2 mpg in most instances, giving automakers that use them a leg up on the competition when comparing EPA data. The new four-cylinder 2009 Ford Escape eked out an additional 1 mpg with the new tires, giving the CUV 21 mpg in the city and 27 mpg on the highway. Michelin estimates that low rolling resistance tires can save $300 in fuel costs at $4 per gallon over the life of tire, which is fairly substantial.
There are drawbacks to low-rolling resistance tires, too. They're more expensive than standard rubber, the ride isn't quite as comfortable, and the tires cause longer braking distances. In fact, Consumer Reports gave the Escape a lower rating because it had such poor stop times. The bottom line is that customers are looking for improved economy at all costs. Since low rolling resistance tires improve fuel economy, the cars that have them and achieve superior fuel economy as a result will be more attractive to mpg-conscious buyers.



The end of an era. That's what we called it when rumors began intensifying just a couple of days ago that David Coulthard might retire from Formula One racing. Those rumors were confirmed today – at the Silverstone track, one day before the start of his home race – when the elder statesman of grand prix racing announced his retirement.
To get an idea of just how long Coulthard has been racing, remember that his first race was to fill the late Ayrton Senna's seat at Williams after the famed Brazilian's fatal crash 14 years ago. Since that fateful start, Coulthard has competed in 236 grands prix to date, winning 13 of them, taking pole position 12 times and setting the fastest lap 18 times. DC spent nine seasons with McLaren, and was instrumental in brokering the purchase of the defunct Jaguar team from Ford by Red Bull, with whom he has raced for the past few seasons, scoring the team's first point and first podium. This weekend's British Grand Prix will be David's last home race, having won the event twice in his career.
So what's next for the flying Scotsman? For starters, he will remain as a consultant to Red Bull Racing, pitching in for development driving, much like his contemporaries Schumacher and Hakkinen still do for Ferrari and McLaren respectively. Despite earlier assertions, however, Coulthard says he will remain open-minded about racing in other leagues, and we could very well see him back in the race seat for the Race of Champions at London's Wembley Stadium in December, however it remains to be seen if Coulthard will try his hand at Le Mans, DTM or some other form of motor racing or rallying. Meanwhile, the vacation of his seat at Red Bull leaves the door open for Sebastian Vettel's promotion from the Toro Rosso B-squad, so sit tight for that announcement. In the meantime we wish David all the best of luck for the remainder of his last season and for life after F1.
