I am a Michelin Fan and run them on all my vehicles including motorcycles but these tires are unacceptable on the Ford F350. The tires squirm all over the road and when towing a trailer or heavy load they are dangerous in my opinion. Having out 3,000 on them I was hoping they would settle in, they have not and in fact they are now out of balance and shaking. After reading others responses they are always getting out of balance. I suggest the M/S 2 tires. Trying to get Michelin to come through on replacing them.
