Have new hole shots. On the side wall there is a couple of bumps. is the tire separating, or what is going on?

 

You will often have a bump on the sidewall on any tire where the belts overlap. If that is all it is, then no big deal. If it is a bubble or something like that, then I would insist on getting it exchanged.

These are some of the toughest tires in the world!

 

They are tough tires and one of the greatest, but i still wore them down in 7 months...No street riding only on the trail..
