Hello,
I'm new here. A LSR team has asked me to do a few calculations. I went to the Aug. 2011 speed week.
I have a few "simple" questions and was not able to pull up answers with the search function.
1 - the current car has a Goodyear Tire with the following markings : 21.0 x 5.0 - 15 and "5XZSM731" - I also see "D2111" on the tire. What is the official model info. for this tire? Is it still available, what is the speed rating? How old is it? Do I ask Tom Burkland?
2 - for the above tire what is the growth as a function of speed?
3 - what are the exact timing device locations that are used to produce the timing result numbers posted on the website and/or printed on the timing slip? e.g. quarter mile ? This is for the long course. Appears to be the following results: quarter mile 1, mile 2, mile 3, exit speed, fastest speed. Is there a diagram? As far as I know the course is 6 miles long. The first marker is "0" this is at the start, so "0" indicates the start of mile 1, right? Sorry for the newbie type questions.
Thanks,
-Henry
