pretty much exactly why I figure that if there isnt any physical markings on the inside of the tire, its probably best not to put in anything, as I know I'll forget about it...but will be interesting to see how the shoegoo works out.
Couldnt find any black, so just went with the regular.
as long as no damage to the threads, you should be fine.
i don't believe the outer rubber provides any support, just the wear-off consumable bit.
but definitely want to protect the threads from uv and sand and water.
shoe goo sounds good. but what about engine gasket goo?
