ESS President Chuck Miller posting the schedule of events for Granby Friday night.TIRESPosted for Tuesday August 4th...................................Interesting.
A new use was discovered for baby powder Friday night at Autodrome Granby. I spotted Tommy Wickham pouring baby powder all over his right rear tire. Why?, I asked. Makes the siper slide over the tire better, was the reply.
Stagger plays a part in the handling of the car. The back tires are two different sizes, the right rear being larger than the left rear, so the car can go through the corner. To see how much stagger you have, you measure the circumference of each rear tire. Usually that is done with a thin, flexible tape measure, circling the tire with the tape. Carl uses a new tool that looks like you are measuring the width of the tire. Actually, it is set up so you get a reading of what the circumference is. Carl checks the air pressure and tire size before Anthony goes out onto the track, then immediately checks air pressure and stagger when Anthony comes off to see how the tire changed. Most times the air pressure will go up in the tire, and that might cause the tire to expand.
Lots of times the tires are ground down to get old rubber off and get to some harder, fresher rubber underneath. Jeff Cook was doing this Saturday night at Drummondville.
