How to get bigger tires on a 3500

[BlackMax 2001]

I know this has been beat to death, but a frien of mine just bought a 2005 D/A 3500 and was wondering how to get bigger tires on his truck. Maybe some can refresh my memory so I can help him out. Thanks in advance for any help.

Brentzwheels and ricksontrucks both have web sites and have wheels to allow the 19.5 tires. A couple of companies also make adaptors for 19.5 wheels. The 19.5 tire and wheel combination give both increased load apacity and curb appeal! 19.5's will fit without a lift.
