i have been running the same tires for a over a year now. put a little over 20k miles on them and they still look like over half of the tread is still on them. i am running a different size though, i have 265/70/18 on my stock wheels and 2wd with no level and they don't rub anywhere. these tires look great, handle the snow and rain great. overall i am happy with them. i too got mine from a local Discount Tire store and paid under $700 for them mounted and balanced and all the taxes and fees. big kudos to DT for the exceptional deal!!!
now, on to the bad review part. as with every Falken tire i have ever owned, these are starting to vibrate. they are cupping in spots and causing the truck to ride worse than i had hoped. i rotate them EVERY 5000 miles, and they are properly inflated once a week just to make sure everything is right. these have a 50k mile tread wear warranty i know, but i highly doubt if i will be able to stand them by then. in fact, in less than 6 months i will be looking to swap these for a less aggressive tread pattern tire. i will be switching back to an all season highway tire.
