I will just add this, I used to have great luck with cooper tires, owned many sets of there discover AT3
however, the last 4 sets have sucked
2016 ram 2500 diesel
first set got less than 22k out of them and bald, they replaced under warranty with the new AT3'XL s that have the side wall like thread to them, they wouldn;t balance for crap, shook truck like mad, COOPER tire got involved, first making me do several tire balancing at other shops, then had to PROVE with having front end alignments done at MY costs(3 in all at different shops, plus dealer) then had to have deal go over truck and state all was in spec
they replaced tires with new set, these were no better! still wouldn;t balance
so they swapped them for another set from another location(warehouse different part of state??) 3 of them DID balance, but one wouldn;t, had to get a new tire again to get that to balance and even then still have slight vibration on them!
and this whole ordeal took 6 months of going back and forth and to different shops and dealers!, and a bunch of out iof pocket $$ on my parts!, I was NOT a happy camper with the purchase of them at all,as I have been in the past!, they DID stand up and replace, but it wasn't cheap or easy dealings!
I now have about 24,000 mils on them now and at about 40% thread left if that!, hoping to make it to about 40 but doubt I will LOL
!
they DO handle well in snow and on wet dry roads, ride well, so not just a bash , just saying my experience lately with them, but I will not be buying again, too much work to get them to balance for me and the mileage isn;t the best on life IMO!
something MUST have changed at there company in quality IMO<
I also will not be buying any Firestone tires, , had 4 sets in a row TRYING to work with them, and never got more than 20K out of there destination AT's, and trust me I wanted to use them, friend works for them and gets them half price, but getting 15-18k out of tires even at half price, sucks having to replace so often! LOL
my next tires will be either Hankook or Falken
