A little background first. 94 FZJ80 with 156K. Heavy/Heavy lift with 285/75R16 Firstone Destination MTs. Tires have about 12K miles on them and a severe chunking problem on one lug on only one tire. All other tires are wearing evenly. I did make it to Katemcy and Superlift Park in Hot Springs on these tires. Has anyone seen damage like this before? I have removed the tire and am running the spare right now. One complicating factor is I bought the tire online and would like to return it to an authorized retailer locally so I am not stuck with freight both ways and mount/dismount costs.
