R they really that Fast?

[dangina]

what tires are the protouring cars running? does bfgoodrich sponsers their tires? I think the biggest reason for the imports winning on the show is they're running Hoosiers A6's Or Advan's AO48's and from the look of some of the tires on the pro cars, they seem like their running bfgoodrich radial tires? It would explain how they are losing grip on the second or third laps and the imports just seem to walk away...
