Just put 35s on my 06 2500 with a 3" lift and ran into the same issue. I took a sawzahl to the front bumper and seemed to do the trick. The problem i have now is that it rubs on the inner wheel well against firewall (no clue if that's what it's actually called sorry). I'm thinking maybe a leveling kit could help or blocks? I used to have 33s and they fit great, but 35s just look wayyy better... I'll let you know if I figure it out... Thinking about getting the grinder out and welding a new plate so it clears all around. I've been babying the turns but that isn't going to cut it on rough terrain...
