Just picked up a new 2013 f250 supercab traded 06 crewcab dually. new truck came with 245/75/17 generals looks like car tires.My question is what bigger size tires can i put on, need more of a snow allterrain tread also. living in NEPA. Plan on adding a 2"' lift also. Just worrying about speedo ratio change and wheel clearance. thanks

 

I just got duratracs for mine. Mine are stock size for 18" rims and they are currently the only offroad tire to also bear the snowflake mountain symbol making them legal for winter use in Quebec starting in 2014.

Don't know about lifts and sizes but one thing to watch out for is to get hub centric wheels. You don't want any 8 hole wheel. What this to understand why.
