The Pirelli KM gravel rally tire is designed for damp, wet and borderline muddy roads. Great for dry conditions with loose and/or sandy roads. Not designed for compact and high speed stages.
Tread is based on the K tire pattern. But has reduced width tread blocks and increased gaps between blocks. Plus the less rigid construction allows better conforming of tire to ground along with easier steering
The KM is currently available in Medium compound only.
Below is KM tire tread shown with K tread shown for comparison. Note the larger gaps on the KM.
