Bruce W Miller on Carbon Upfront!

The Izetta was my first street legal car I learned to drive with .;-) Early vehicles were go-karts and road racing cars while growing up in Germany. Anyone doubting particulates and stuff coming off tires has not been to a road race circuit where the outside of nearly every turn will have piles of rolled up rubber (called marbles) and tiny dust-like particles that comes off of car tires while cornering and braking. Depending on the number of cars and classes black "drifts" of this stuff can be seen blowing across the road from the air movement from every car passing by. Massive impact on the highways where it may be more evenly distributed. So aside from the obvious huge truck tire strips separated from tires that are routinely seen along side major Interstates in the U.S. tire wear and of course brake pad material also is coming off! My US $.02 wroth, but at the current exchange rates and falling US $ this may not amount to much.
