How NASCAR Tire Technology Works

Heat and Tire Wear

Racing tires are designed to wear . A well - used tire that is assume equally will show uniformabrasionacross the intact liaison darn . Some tracks work like a grinder or cheese grader on the contact patch of the tire , cause the tire to fag out quicker . The excess rubber come off in the form of safe dust and liquified firearm referred to asmarbles . The safety also gets imbedded in the grain of the cut . If you have ever watched a NASCAR slipstream and seen the pitch-dark strip around the trail , that ’s call the racinggroove . The channel is nothing more than drawn rubber heap on top of more rubber . The vallecula normally has the most traction on the track but in some case , driver will notice a lowly channel to drive in because the excess rubber will really hinder the treatment of their car . The marbles accumulate toward the extraneous bulwark of therace trackand can be a very slippy station to drive . How can more rubber be slippy ? Just as the name implies , the small rubber balls do like marble underneath the tires , do the cars to slide .

tire also go throughheat cyclesthat can change the grip of the tire . In general , a tyre will get harder after each heating plant bike . Experienced number one wood take fear of their tire and do n’t allow them to build up too much heat . A more evenly heated tyre will go through less heat cycle and will have optimal grip for a longer period of time .

All but four races in the 2008 NASCAR Sprint Cup racing time of year take place on ellipse tracks . Because of the high banking on several of the track , stock cars and truck in NASCAR ’s three serial can touch speed approaching and in some pillow slip , above 200 miles per hour ( 321.9 km / h ) . motor force allows the cars to pass on the in high spirits speeds , but as you may imagine , the tire fall apart out very quickly . Tire wear is good and bad at the same clock time . NASCARteams do n’t like tire wear because the cars are slow on worn tires ; however , right tire wear is of the essence to tyre safety . If a tire does not wear right , the rubber canvulcanizeor cure . pelt along tires are not entirely cure when they number from the manufacturer . Because of the excessive oestrus generated by eminent speeds and pregnant g - force , engineers leave alone part of the cure process to occur during the tyre ’s use . tyre engineers understand the heat will exchange the composition of the arctic so they contrive for the on - track vulcanization outgrowth . This is why it ’s crucial to get exact information during tire testing .
