I am looking at the M-550 A/S. Comparing the specs to the BF Goodrich traction t/a's, Kumho Ecstasx and the Yokohama Avid H4s it would appear that the Avon blows them all away. There have been some reviews about the Avon's flat spotting and behing hard to balance. Anyone have any experience with these?

 

i have had avon 35" tires on my truck for the past 40000 miles.they are the big mud type and still have about 50% of tread left.i think they do need balanced i have a bad shake at 70 mph. but overall i like them.
