I got the Michelin Latitude Tour HP's installed yesterday and they are, IMHO a perfect match to the Overland with 20" wheels. They simply work
Ride comfort is excellent
Steering response is better than either the factory Goodyear's or the Yokohama's
No vibration at any speed (both the Goodyears and Yokohama's had an annoying vibration between 65 - 75 after repeated balancing)
Excellent grip with very linear turn in and grip up to the limit
Overall grip is probably as good as it's going to get with the factory suspension
Noise is a tad higher than the factory Goodyear's but it's white noise and not intrusive (wind noise overcomes it at speed).
Based on the road manners over my "test loop" I expect the towing performance is going to be just fine, especially if I air up the rears to around 42 lbs when under load.
Time will tell how long these last but based on the improvement in overall feel my personal opinion is they are well worth the money. Sure, you can get cheaper tires but if you want the best ride and performance spend the money, you shouldn't be disappointed.
