Spark, rubber does not follow Newtonian friction rules; Ff = u * Fn doesn't cut it. It's an element, but there is also the interference with the road irregularities and at high levels of stress (hint: when you're at the limit and the tires are up to temp) there is actual chemical adhesion going on. There are entire textbooks written about modelling tire-road interactions.
