I don't know who the inspired prophet of kids toys is but the guide that suggested using 16" bmx tires for traction on the power wheels was right on point.  I read the guide on monday and my first stop in the morning was walmart.  I found the tires and when i got home from work put them on the jeep hurricane.  The sage one was right; the treads fit so snug that no glue will be needed.  we live on an incline and the jeep can now traverse any obstacle.  you are some kinda genius or something!
