The question is: Are you driver enough?īased on internal dry handling and internal wet and dry autocross test results using a 1995 BMW M3 lightweight and a 2011 BMW 328i vs. Whatever thrill you’re chasing, BFGoodrich ® tires will make sure your vehicle’s up to the challenge. So it’s no wonder why top driving schools like Ford Mustang Racing School and Skip Barber High-Performance Driving School, use BFGoodrich ® tires exclusively. BFGoodrich ® street tires have racked up impressive accomplishments over the years - from creating the first street tire to capture the pole position at the 24 Hours of Le Mans to creating an entirely new level of street tires, the extreme performance category. BFGoodrich ®'s performance prowess doesn't stop where the pavement starts.
That’s why more champions of the grueling SCORE Baja races have won with BFGoodrich ® tires and why the tire with more rock crawling victories bears the BFGoodrich ® name. It’s what led us to the pursuit of creating truck tires tough enough to tackle some of roughest terrain on the planet, yet still maintain excellent road manners. As a maker of superior performance tires, we’re proud to say we’ve been passionately performance-driven since the beginning. Once there is no longer any overlap between the tyre/rim marks then maintenence us needed.Passion, pride, and performance are BFGoodrich ® values that have stood the test of time. Usually the width of the mark is determined by the allowable creep as defined by the manufacturer. There you have marks lining up on the tyre and the rim, showing no creep.
Now imagine that one of the breaks is a little stuck on, the torque on the tyre is then amplified and it can slip on the rim, this is known as tyre creep.īecause it can be an indicator of a further problem, such as sticky brakes or just a particularly hard landing, aircraft tyres use 'creep marks' so that pilots can visually check their tyres each flight. You know how you see puffs of smoke from the tyres when planes touch down? That's because the poor tyres are having to go from stationary to 100+mph in an instant, all whilst being loaded up with the entire weight of the plane. The exact thing you describe is actually a pretty common problem for aircraft tyres. I never thought about the math relating to tire pressure, that's quite a bit of pressure and it all makes sense.Īll the replies here are about cars/bikes so thought I'd add another perspective. So how come if someone floors the gas, the wheel turns and the tire too? How come the wheel doesn't spin loose inside the tire.Īren't tires just rubber around the wheel? How are they so efficient at transferring the power and staying "timed" with wheel?Įdit: Thank you to everyone for your explanations! All very simple and straightforward. If I firmly hold the rubber with one hand and turn the pen with the other hand, the pen moves independently from the rubber (when I apply enough force). Or to put it another way, I have pen that has a rubber grip.
I get that tires are "sticky" in their contact to the road, so what keeps the tire from continuing to rotate while the wheels stay fixed in place? I would expect the car to slide like it's on ice. Let's also say my brakes are good and completely stop my wheels from spinning (the wheels lock up). Let's say I'm driving down the road at 50 mph and I forcefully press on the brake pedal.
