I used the Goodyear ATs on my 89 and they sucked in the rain really badly, next I tried BFGoodrich ATs for there better wet road traction. I used them till my 89 hit the GY. Honestly I don't know if i would recomend either.
Tires - WildPeak A/T - Falken Tire
This is a brand I tried out on my Expedition, I am highly pleased with both its on and off Road characteristics. This is a Daily Driver tire with more agression.
If your looking for strictly a mud tire with good street manners and have deep pockets I really like the Mickey Thompsons. I used these for my on my Jeep for 2 years when it was my daily driver. I got over 10,000 miles on my set.
Still have the nipples on them, I have run these tires through plenty of rolling trails, mud holes, and creak beds, they have held up well.
Here is a few links of the tires.
