Toyo fans, check your tires.

Dirtyoil, your the first person i have ever heard that had a problem with M55's. There are more of those on trucks around here than any other tire. I have worn out several sets myself without issue. Did you take them back to the tire dlr ?

Yes I did, dlr tried to tell me it was a weight thing... too much!? LOL, went to another dlr had them put in the paper work. Got a rebate from Toyo which I used to purchase General Grabbers. The roads I travel/work on, allow me to wear tires out faster then most. So, I get to "test" the different tires. I did like how the tread was wearing on the M55s, far better then BFG, better then Cooper SST, Dick Cepek FCII, and tenfold better then Dunlaughs. We'll see how the Generals work out. Thinking there might have been a bad batch of M55s that I received. Only 3 of the four showed the splitting/cracking. As you pointed out, lots of users, that was the reason I went to them in the first place. A lot of guys running M55s up here, reports of long lasting tread and weight capacity, good traction in both mud and snow/ice.
