You mean the LE-3, right?
I had a set of LE 2's a while ago on a SUV, The LE 3's are newer, but similar tread pattern. Firestone offered me a heck of a deal b/c it had been a slow day during a college football (home) game. They said, if I bought them THAT day they'd give me this xyz price. I did, and they turned out to be among the smoothest tires I had owned in a long time. And quiet. I was impressed. I would have bought a set of Firestones this last time around for a different vehicle (not Ram), but their A/T tire they dropped the rim-protecting bead ...which was one of my "Must-haves". But overall, I've had great luck with Firestones and wouldn't hesitate to buy.
I can't compare it to Falkens. I've never owned a set. They didn't have both OWL and a rim-protecting bead last time I was looking a couple yrs ago (not Ram). I just can't buy a set of ugly black tires w/o white letters...lol, (Yes I am THAT shallow...ha ha). And a lot of competitors DO have the rim-protecting bead on their AT tires. So in that case I went with the Hankooks.
Last time on my Ram, I shopped around and ended up going with the Walmart Coopers
HERE. They were both great-looking and *far* less expensive than anyone else. Pretty good tread too. I was concerned due to some bad previous Cooper experiences (many yrs ago)...but these A/T Coopers on my Ram run out super. It's going on the 3rd year for them now. I even bought two more sets of them for other vehicles (I have several vehicles). And those others run out great too...one set is a 10-ply rated. So I've been happy with the coopers.
I've tried many, many brands of tires over the years. But not Falkens...for no reson than it just worked out better on some other brand at the time. Lot of guys here have positive feedbac on them. I wouldn't hesitate to go with the Falkens...just as I recall they didn't have white letters for my size and were 25% more expensive than the Coopers last time. The Walmart Coopers come on sale a lot, so keep your eyes open. Their one tire is exclusive to them, nobody can touch that price when they do. And that's the time to buy them. They also mount for free and a $3 disposal (or used to be the case). But I had mine balanced elsewhere on a Hunter Road-Force Balancer.
You might call the Firestone dealer and see what 'deals' they have running. They're always running something this month or next. If you do the warranty thing (I never do)...but if you do, you can get them warranted at many Firestone dealers, which is kind of nice. I think Discount Tire has the Falkens...and they have a lot of outlets too.
