Another snippet of useful information is tire pressures. Starting pressure depends on the time on track. I aim for 39 to 40 PSI hot. For runs of 5 minutes or more I start around 33 psi cold. For a real short run you will need to start closer to the final temperature you want. This applies to the Kumho XS and Hankook RS-3. I don't recommend the Yokohama Advan AD08 because they fall off when hot and even more after being half worn. The Kumho's and RS-3's stay good to their death beds and handle the tropic heat well. When new, the AD08 is excellent.
