I don't under stand 10mm offset. Offset is based on wheel width. (7"rim 5+2, something equaling the width of rim) what I would do is contact place of purchase they will recommend offset based on pioneer 1000, and tire and rim size. Width is issue for tire clearance on suspension and tie rods. If you stay with factory size tires, and go with recommended offset you should be close to stock width. Hope that helps.
