Just a tip about buying tires at some discount stores. Most discount stores and even some Discount tire stores do not carry the top of the line tires. If you got to brand name tire stores like Goodyear, Firestone, etc you will have a better selection of tires.
Most people here don't care for Goodyear tires, especially the Wranglers that may have came with their Sport Trac, but Goodyear makes a lot of different models of Wrangler tires.
I had a set of Goodyear Wrangler RFA's on my 2001 Sport Trac as replacements for the recalled Firestone ATX tires back during the Explorer/Firestone fiasco in late 2000. The RFA's were Rotation Free Aqua treads and had a different tread design for the front and rear tires. I put 42K miles on those tires without a tire rotation and they looked brand new when I traded it in for my 2003 Sport Trac. I never had any problems with the RFA's, they were smooth riding, quiet, with excellent wet weather traction throughout the 42K miles, and I never even had a flat tire. I even drove through a tropical storm in Arkansas where the rain was so hard that people were pulling off the highway.... With the Aqua-Treads and RainX, I kept driving at 65-70 MPH like I was on rails..:grin:
Goodyear does not make the RFA's any more...I think they were replaced by a TripleTread model, but Goodyear does make some good tires as does Firestone, and Michlen, you just might not be able to get their best tires at Wal-Mart or Discount Tire stores.
