One was the original one I'd patched, and the new one very close to the edge of where the old patch had been (outside of the edge). I had an oversized patch, so I applied it. Just wondering if you can do that - will one patch work for 2 holes that are close together? It wouldn't have been possible to put 2 patches on. Won't know until I get the next flat and replace the tube with the one I just fixed.
Thanks.
the second leak was ,probably, already there... and the patch got applied off to the side a bit.
"Snake bite" punctures usually happen from tires being at too low of a pressure, or curb hits, that pinch the tube from the top and bottom.
i've seen tubes caught between the tire iron and rim, or between the tire bead and rim, get snake bit too.
if the patch was applied well, and the Tube was properly prepped, and it's not a "peel and stick" patch, it may hold up fine...
my unwritten rule on tubes is.. if they already have two patches, then i won't patch them a third time.
