A buddy of mine has a set, as cool as they look they are USELESS. They weight 2lbs EACH and are super bouncey and even with 17mm hubs they are easily stripped if not ultra careful.
Ditch them and get some Savage XL tires, Cen bowties or Proline Moabs.
These are the CEN bowties and are 71/4" tall and are 15ounces each and are the lightest 7" tire availible. The CEN chevrons are way cool looking but weigh considerably more.
FYI, these rims are 23mm hubbed, you can score CEN 23mm hubs on Fleabay for under $20.00 delivered and they fit the LST2 axles BETTER than Proline hubs/.
