Not sure where to buy them online. here's the deal...when I asked the question the guy was putting the tires on my jeep. it's bone stock except for cosmetic upgrades...i went riding around to find some mud for a few minutes, and i did. These tires drove right through a mud hole i got stuck in about 3 mos. ago. They ride well, give great traction, and so far have not whined one bit. I've only driven a few miles on them, but so far I'm pleased. I'll let you guys know about whining on the freeway after i get to work tomorrow.
