Good tip to use the FIND function.
To try to help (with my somewhat limited knowledge on the topic), my two cents so to speak, it sounds like tire height and width need to be considered along with rim diameter. The large the rim the more likely a wider tire will hit since the "bulge" part of the tire is more closely located to items with less clearance.
