BFG Racing Tires

BFGoodrich designs and produces some of the toughest, most competitive off road racing tires on the planet. BFG NON-DOT race tires are designed specifically for off road or closed course use and not approved for use on public roads.

BFGoodrich KR3 40x12.5-17 

Evolutionary design of the winningest tire in SCORE desert racing history. New tread pattern, profile, and sidewall design for improved traction, steering response, and overall performance

Race only, non-DOT not legal for highway use

The latest iteration of the legendary BFGoodrich Baja T/A the KR3 / KR3-S takes steering response and transitional handling to the next level for unlimited class desert racing vehicles.  Using the race wining Baja T/A KR2 as the foundation the KR3 evolves into a 40×12.5R17 radial race tire with tough sidewalls and an aggressive tread pattern to take all the desert can throw at it.

Tested in the 2015 Baja 1000 and early season 2016 desert races the 40″ KR3 is designed for current generation unlimited 2wd or awd Trophy Trucks competing in SCORE and BITD.

  • 44% increase in number of biting edges vs KR2
  • 1.25 inches taller than KR2, 1 inch narrower
  • 5 lbs lighter than 39″ KR2
  • Lower rotational inertia than KR2 despite being larger in diameter
  • More progressive traction, more predictable lateral grip
  • Significantly improved comfort (and speed) through bumpy terrain
