I am going to be purchasing new tires for my 08 JK. I am considering the Hankook Dynapro AT-M, General Grabber AT2 or the Goodyear Authority. I like the look of the Goodyears the most buy Im a bit skeptical because they are a "walmart tire". Any input would be appreciated. I am looking to spend under $180 per tire in size 265/70-17.
