Had a scary rear slide today wanted to figure out why?

Turn was a tight left hander, uphill, slightly on the throttle and my rear started stepping out.​I scraped the peg, luckily have folding pegs, and regained traction.​Spoke to my buddy about it later and he suggested lowering pressures to 32 rear (hot). Was running around 36 hot.​Tires are q3+ with a few weekends on them​Had suspension tuned to my weight recently, but still experimenting with pressures.​Is 32 hot ok to run on the q3+ ? I was thinking maybe the tires were just getting a bit old/on their last legs.. via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/bqc22c/had_a_scary_rear_slide_today_wanted_to_figure_out/?utm_source=ifttt
