These Firestone Destination A/Ts are great! I now have 66,000 miles on the tires and it looks like they could last another 5,000 miles although the tread has started to cup in the last 3 or 4,000 miles. The tires were rotated every 6-7,000 miles and I've had absolutely no problems with tire balancing throughout the life of the tires. Even though the 4WD Expedition is tall and heavy, I have a tendency to toss the SUV around corners as if it was my BMW 530i or M Roadster. The tires don't squeel under hard cornering and are stable under quick lane changes at freeway speeds. I can't comment on the tires off-road performance since the closest thing to off-road use on these tires would be mud and gravel trails. If you drive primarily on highways and cities, this is the tire to buy for your SUV.
