Not Talking section width I’m talking treadwidth your tires are 10.4 inches. When I bought them you convinced me the widest treadwidth was the best thing for stability. If your tires tread width is wider the tires are going to stick out further.
Don't disagree with you. Just trying to stay on topic to sort out the issue with the spacer. For any particular tire, the whole tire needs to fit. Including making room for section width. While spacers are not my first choice, they are a useful tool to certain fitments.
