I have a Avon Trike tire on my 2012 Goldwing and at around 10000 miles (8 months old) it developed a slow leak. My friend is running the same tire on his Goldwing trike and and now at just under 10000 miles (16 months old) his developed a slow leak. Both are leaking at rim. I was wondering if anyone else has had a problem with the same type leak?
