ok guys i have a question about my bfg mt's.
i purchased 5 mud terrains from a local shop here called affordable, 2 or more have chunks missign under them, i was in 4 wheel parts today with an unrelated question and i mentioned that they were chunking and they said somethign to the extent of bfg's never chunk you should have them checked. Of course i was not in my car, its beign painted(see vandalism). So they could not confirm, but should bfg cover this. What should i do, or is this normal. I havnt been driving aggressively, very conservative especially for me. Any help would be greatly appreciated.

thank you Mackie
