I have just over 51,000 miles on the BFG Long Trail Tour tires at this point. I can certainly get another 10-15k miles out of them before they hit the wear bars, but will replace them before winter as the tread depth is getting to low for snow. Compared to the OEM Continental ContiTrac SUV they are amazing, but the BFG's are a touch louder. The Conti's were just barely adequate and were out of round from day 1, but did last 81k miles before the wet traction became unsafe. The BFG's, as expected, reduced fuel economy by 1-1.5 mpg, but the handling improved exponentially. Dry traction is very good, wet traction is amazing and surprisingly snow/ice traction is pretty dang good. I drove through 20+ of snow with them and decided to go to 2WD just to have some fun on the un-plowed back roads in WV. I could not believe they handled the snow almost as well BFG All-Terrains. In hard packed snow I could use near full throttle to accelerate from a stand still before spinning all 4 tires. I go to work regardless of the weather so they were well tested and I was truly surprised.
I push these tires in turns very hard and they have never disappointed me no matter the road conditions.
I'll be getting another set later this year since nothing else available seems to be as good to me. If I could afford to though I would absolutely mount up some BFG AT's, but they are almost double the price for 17 wheels.
I run the tires at 41psi front and 39 rear. The ride a bit stiffer this way, but with air suspension it's negligible, but the handling improvement is amazing. I monitor tire pressure and tire wear very closely and have never worn a set of tires out in the center due to exceeding the vehicle manufacturers recommended air pressure, but before I ran higher pressure I did wear out the shoulders of the tire tread. I also only tend to rotate tires only 1 time during their life span, these were rotated at around 40k miles and that's it.
