I agree. I had them on my older coach and did not take them off, What a bad idea. Will not do that again.
I just got a new set for my new coach and will install next week with new Michelin tires, FMCA advantage program is a great help, saved over $150 per tire.
Since balancing cost $30 or more per tire the centermatics are not a bad deal. Yes the cost a little more up front but save in the long run.
