06 F150 Supercrew w/2" level front & 1" spring spacers back. Aftermarket '03 Harley Replica 20" X 9" wheels. Have 275/55/20 Pirelli Scorpian ATR now. What is max size? Best AT & best mud? 90% on road. Looking for a little more aggressive looking tire but not a "Swamper".

 

Is your truck a 4x4 or 4x2? Also, did you get Harley replica wheels with your bolt pattern. I know the old style Harley replicas are available with the new 6x135mm bolt pattern, but they are scarce. As for tires, I'd recommend the BFG AT KO, Nitto Terra Grappler or Toyo Open Country AT.

 

It's a 4x4. 6 lug wheels.

 

Went with the Nitto TerraGraplers 305/50/20. Love them! Thanks.
