The COSTCO tires are Greenball. Never hereof them, but made in USA. We will take metal valve stems for the new tires. You have to take the rims to them, they won't mount them an the 5er. The old tires are Maxxis....
IMO, you're taking a step =down= in quality. The Maxxis are, by all accounts, the best ST tire you're likely to find. I predict you'll get much less life with the Greenball and probably have some issues. Keep any eye on them...like a hawk. Steel stems are the way to go.
