I just added 235 85R 16 tires and wheels to my 2005 B2300, now I need to add a couple inches of lift in order to keep the tires from rubbing. (They only rub at full left or right turns) I also don't want the tires to hit the fender wells when I go over obstacles. The Haynes manual says that there are Torsion bars on the truck but when I put it up on the lift I found that the Haynes manual was probably just generalizing since it covers the entire series of Mazda and Ranger truck from 94-06. Need advise !
