i actually have the same tires on my 89, they are a very good tire, my grandpa has about the same things on his 97 but he has the more aggressive tread and it picks up every rock on the road.

 

Duratracs are good tires. Goodyear also has a tire sold at walmart that looks like a duratrac, it's the Wrangler Authority. I run them, have for 30k miles, and they're stil over have tread and great on and off road. Those are $143 locally for me.

2" level - 50 bucks on ebay, factor in the 40-80 dollars for adjustable camber bushings (install yourself, save 200 bucks, only takes an hour), and about 120 for install if you can't do it yourself (also easy)
