<strong>Yahoo Message Number: 107327</strong>I am thinking about carrying a spare Michlin XZA2 315 on the rear roof section of my 45' Affinity. Does anyone have any experience with that. I will have a vinyl zipper bag made to protect the tire and will isolate the tire from the roof with a pad. I am a little concerned about the weight.<br/><br/>Terry Ray<br/><br/>08 Affinity 6837
