I just received my new drag radials. These things are huge. 315/35/18's. They measure 12 7/8 inches wide. They are an inch wider than my 305/35/18 nitto dr's. Has anyone mounted a 315/35/18 on a 10.5 inch rim? I know they will fit with the offset i have but i am worried they will stick out farther than the 1/4 inch i was thinking. Do you think the tires will narrow a little when they are mounted?
