well just thought I would give an update, if anyone cares, yep too much time available to do stuff. We have made another trip, about 1000 miles and I am happy with the tires. they run cool, actually may help a little with gas mileage as they are smooth and have very little friction. so since I originally "May have put the cart before the horse". It has all worked out. Also the cost right at $1000 was acceptable. so again, thanks for listening and providing your feedback. have a great day.
