You know since posting i did find some really cheap from Northern Tool, but am so confident this will work am gonna continue to use them until whenever and just put the new ones on the shelf until needed. If i'm wrong i'll let everyone know but as nice as they're working i doubt i'll need the new ones. I mean i got the tire covering the foam and the foam is in the tube so no weather can get to the foam to break it down.
