Now we are cooking with grease. Visual aid, I like it. I have a 7 1/4 so sounds like the 275 on a 8’’ wheel with 4 1/4 BS will work. Right? If so back to 2 of the original questions. The spacer? Do I need to do that and how much room will I have from the top of the tire to the top of the wheel well? Thanks 66fyssh! Appreciate the info, I’ll hang on to that.
