I just went to a Goodyear Dealer last week and was quoted out the door for G614's $300 per tire, including steel stems, disposal of old tires, and mounting and balancing with tape weights. Every single tire dealer I went to told me to stick with the dreaded E-rated Michelin XPS tires, as they all said the G614's are 14 ply, and will shake the trailer up pretty badly while traveling. All said G rated were over kill. On the other hand all the senior RVers here in the forum swear by the G614's, even on 6,000 lb axles. I, myself am in a quandry about these choices. How stiff of a ride will it be, does it affect the ride in the truck, as I have a bad back?
I have asked this same questions on other treads and haven't really gotten solid answers. Steel stems are a must if u want to use the pressure pro system, sold by Pat McFall. You get a set of 8 so can include truck tires as well.
Ears are wide open, opinions needed.
