The latest issue of Sports Car Magazine (SCCA’s magazine) had an article where they tested all the top street tires for autocross. Thought I’d share the article highlights for those looking at STX tires (or maybe just a more durable, cheaper substitute for R-comps).
All tires were tested on a STX spec 2005 Mazda RX-8 running 265/35/18 tires on 18X9 wheels. Curbweight of the RX-8 was 2800 lbs. (driver not included).
Another important note was that all tires were shaved to 3/32″ tread depth to mimic a top national driver’s setup.
Track conditions were all sunny and dry. Ambient temperature at 75 with a track temp of 105.
