I was wondering if 305s would fit under a stock hd01 3/4ton

 

yes but it will probably rub when you turn or flex to much. Jsut go with 285/75/16 they are just a little smaller and shouldnt rub. or crank the torsion bars up.

 

I'm running 285/65/r16 (pirelli zeros) all the way around with no rubbing @ all.

 

Just came back from the tire store. Went with the 305s on a last minute decision after discussion with a fella at the shop. Cranked the torsion bars about an inch and a little trimming, but it was worth it. I'll try to get a few pics up soon.
