I purchased a set of Kuhmo 730s to replace Supercar 3Rs on my track wheels. Nothing changed with my setup, other than the tires. I run a 305 square setup, and rotate after each event. I assumed that I would be giving up a little bit of grip, going from the 100 treadwear 3Rs to the 200 treadwear 730s, and that was certainly the case. But, I also expected better longevity from the tires. However, after half as many track days, one of the 730s (the one on the front left at the last event, i.e., most loaded) is showing threads on the inside shoulder. I find this to be very strange (and disappointing, to be honest). With approx. -2.5 deg camber up front, the 3Rs wore out much faster on the outside edge. This was not surprising, considering that most guys with dedicated track S550s seem to run -3.5 deg up-front (since this is a daily driver, I didn't want to go more than -2.5). I try to run the pressures in the mid 30s, hot (higher and there is no grip at all).
I'm curious if there is anyone else out there who has used both of these tires for HPDE, and what their experiences and/or observations are?
