Federal Rally Tires have experienced success in the Australian, New Zealand, Indian, Chinese championships as well as in the FIA Asia Pacific Rally Championship. Rally.Build was the first USA company to import these tires for testing back in 2015 and have been using them successfully ever since. We have tested nearly every rally tire on the market and firmly believe these are the best tire for the money and are an exceptional value. Currently only available in one compound though we have used this compound successfully in all conditions ranging from the 100 degree heat of Rally Colorado in July to the frozen gravel of Rally Kananaskis in October in Canada.
The Federal G-10 is a multi-purpose gravel tire and is directional.
