2013 Chevrolet Silverado 1500 — tires or pads first for a beginner autocross season?

Write down what you already tried. A second data point from another 2013 Chevrolet Silverado 1500 owner helps more than a generic diagnosis. That's where I'd start. This is from a 2013 Chevrolet Silverado 1500 in Philadelphia. That's the whole play. I'd sleep better after that step, even if it finds nothing. This is the version I'd tell a friend.
