Mike, I made the mistake of getting talked into lugged tires for the rear. Big mistake, cause I ended up taking them off and replacing with steers on the rear. They were loud, and the handling definitely deteriorated. My theory was the lugs made the tires squirmy. Just my .02

and you didn’t ask, but 6 yr old tires ESPECIALLY if the coach has been sitting, should be replaced. Sitting is the death of tires.
