After doing some research on tires, I decided to take a closer look at the tires that were already on the car. Originally I thought they were just normal car radials as they didn't look like anything special to me. On closer inspection I found they are Toyo branded Eclipse tires, and have the M&S just beyond the tire size. I might keep them awhile to see how they work out. I don't do any rock crawling or serious four wheeling like I used to, but would like to follow mountain roads without getting stuck.
As an aside I found out the guy I bought the car from is some sort of backpacking and camping guru in the state of Idaho. Seemed like a real stand up guy. So far the car is everything he said it was.
