I certainly would be concerned about the former. If it's the latter, I guess my current rears are indicative of how it will look (kind of "meaty beefy" lol ).
Well, both really. The inadequate support from the rim will diminish handling and steering feedback. You are better off w/245 on 8.5 rim. Remember that non-rft tires have softer (regular) sidewalls. Check-out tracking section for additional details. Since you want to learn I would post your question in the tracking section and you will get all the details from experienced drivers. Make sure you do this right cause it will impact every mile you drive. :-)
