I don't have any experience with Nokians, but I can tell you that Wranglers are not what they used to be....
Many years ago when I had an 04 Explorer (26K @purchase), it came with new Wranglers and they lasted almost 70K miles before needing replacement. However, when I bought my current 011 Expy (58K @purchase), it also came with new Wrangler SR-A's, but they only lasted about 30K.
Both vehicles were in excellent condition when purchased and had been well maintained by the previous owners. So I replaced them with Steadfast HT's, which by all accounts is a little heavier duty and better sidewall/tread construction as compared to the SR-A's, but only cost about $30 more per tire..
So fingers crossed that they will last longer than the SR-A's did
A side note, I am partial to Goodyear because I have had them on several mid-sized sedans in the past and always got at least 50k out of them....I know those were much different vehicles, but just sayin....
As for where to buy tires, I can concur with NEVER, EVER, buying them from the above box stores, since they are primarily made specifically for them and to hit a certain price point and nothing else.... and also, when they wear out prematurely, those places will absolutely REFUSE to give you a prorated warranty replacement, and neither will the mfgr, as they say that those places are not "authorized" dealers for their products and will tell you to go F yourself
