I will definitely keep centramatic balancers in mind. Have website in my favorites. Many members have posted positive feedback regarding using them. Since these Dyna trac tires came match mounted , 2 balance bags inside, and some sticky weights I will keep close eye on them. The managers at commercial tire shop told me just to rotate and do not balance the tires every 5000 miles. Also told me that the ride should get little better with more miles on tires. have a little over 2000 miles on tires now. my tires are Dyna trac PD 890 245s 16 ply tires.
