I have a set of (4) 15x10 6on5.5 beadlocks. Inner ring is steel and putter ring is aluminum. 32 bolts per wheel. Hardware comes with them. I ran them for several years and just moved up to 17s. I'd like to get $400.00 for the set. I'd be willing to ship but it will be on your dime. Located in Baton Rouge, LA
