I patched a nail hole in the sidewall of the original rear tire that made two holes (in and out) without a problem. The Metz has so much sidewall that I figgured it would hold up fine. They overengineer the sidewall and leave the tread wanting. I wouldn't have any issue at all running a properly patched tire, no matter where the hole was. The Myth of not patching sidewalls comes from older tires that had alot of sidewall flex, the patch would work loose. Worst case is that the tire leaks again, it won't just fail.
