Just for the record, one of the Marathons that came with my 5er blew out a while back during the winter while sitting beside the garage. Come spring, there was a piece of sidewall laying beside the flat tire. Another one had a large bulge on the inside, just waiting to blow. Replaced all with Maxxis range E on recommendation of many members of this forum, and have had no further problems. JMHO
