AKA I-Beam 1/8 Truggy Tires, Hard Compound w/Foam, Pair
The I-Beam is designed for traditional tracks with a little bit of loose dirt. The larger lugs allow the tire to dig deep for maximum traction when it is needed the most.

Notes from the team:
Running I-Beams all the way around will provide a very neutral and easy to drive car with tons of forward bite on any loamy track. For drivers who prefer a more aggressive setup that yields more steering, try the "City Beam" combo (City Blocks in the front and I-Beams in the rear).
