July 29, 2011 - I've been reading up on the Toyo R1R tire a bit.
Apparently the reason they were so greasy last week was that I had the pressure too high. They like surprisingly low pressures. I started at 31 cold last week, but next time I'll drop it down to 27 and work from there. It's a bit of a challenge trying to anticipate how much the tire pressures will rise over the course of a stage versus a 5 minute track test, but it'll give me somewhere to start.
It's interesting looking at the different wear on the front and rear tires (middle and right positions in the photo). The front is showing some scalloping while the rears just look overheated. This particular set is being abused heavily so I can determine how these tires work and last.
