The latest iteration of the legendary BFGoodrich Baja T/A the KR3-SR (Soft Rock) is designed to tackle the rocks, dry lake beds, and valleys of Johnson Valley, CA home of the legendary Ultra4 King of Hammers each February. The KR3-SR takes rock climbing, steering response and puncture resistance to the next level for unlimited Ultra4 Class 4400 rock racing racing vehicles. Using the race wining Baja T/A KR3 as the foundation the KR3-SR evolves with supple sidewalls for climbing and an aggressive tread pattern to take all the desert can throw at it.
Tested and raced by multi-time KOH winner Jason Scherer the KR3-SR won KOH overall in 2018, 19, and in 21 with Randy Slawson/Bomber Fabrication.
