This is a very tough issue to answer. Do 4x4's with street tires cause surface issues. Yes, street tires in general cause surface issuses, especially if the track is not prepped correctly. This all depends on the class that is racing, and the surface of the starting line itself. Top fuel racers complain about the Pro Stock cars causing problems. And they do, but that's racing.
I don't think that soot itself is much of an issue. I know some racers complain about it, but I actually put down less smoke going down the track then a lot of gassers do. Raw fuel is another story though. If someone blows a boot (for example), and keeps legging it down the track, that can for sure put raw fuel on the track and make it very slick.
Most of my racing is with other cars, not in diesel only events. I have yet to this date had someone complain to me about me causing track issues. I do however on a regular basis ask others if I am causing them issues. When racing other cars, smoke (smoking out the lights), is probably more of an issue then soot. I've spent a lot of time, making sure that my setup doesn't do that.
