Reading your rubber tires
What are some clues for your set up you can get from looking at your tires? Its pretty easy to see if your camber is correct with foam tires, but with rubber, is there any clues?
Our track only allows Jack the Gripper, and I have been using CS27s. Is the pick up/graining/blistering (I don't know what you call it, its like eraser shavings that stick to the tires that you can easily scratch off with light fingernail pressure) a clue? i don't have a personal transponder so checking my lap times, unfortunatly, isn't an option, so should I be getting this pick up on the tire? Driving problem? Stop grinding the tires; less slide more glide? If I run out an entire pack (15 minutes) the build up is hardly there, if at all. If I didn't like the set up and quite early, it is pretty heavy. If the car feels good, and I start driving well, the tires start to make noise in a couple of turns, kind of like a low squeal. Sometimes it's a sort of machine gun chirping sound, which kind of leads me to the question if I have a camber issue, or I just need a damping adjustment.
I ran off road for a while. then I bought a used FT TC4 with foam tires, used them up, now moved on to rubber premounts in anticipation of eventually racing it (the foam class seems to have died here). I started with the manual recomendations for each tire type, and made small changes from there. I am using a one way in front.
