I have a set of 4 MBS 8" wheels on rockstar hubs. I used these wheels 4 or 5 times then switched to another set so they are in very good condition. There are some balancing weights on them so if you reinflate you will probably need a rebalance. 2 of the wheels are in bags because I took them apart and never rescewed the hardware back together, I can re-screw them before I mail everything out.
$135 total for the wheel set which includes shipping to anywhere in CONUS.
