I'm running a Toyo AT III (255/60) on EOM 19" wheels. That's a 31" tire with an additional 1/2 of sidewall, which is a modest improvement over stock. But when compared to the 255/50R20 tires I assume you're running, you get a full a full inch of additional sidewall (6" vs 5") which I think is a worthwhile improvement. Allows for airing down just a little, with the caution that airing down too much makes the tire prone to bruising and or puncture--especially since they're not LT tires. Of course, not being an LT means a little less stiffness in the ride and theoretically a little less weight. I'd say they're a moderate all terrain pattern so I was pleasantly surprised with performance on muddy WV trails. Reasonably quiet on-road performance. It was the right compromise between me and my wife. The 255/65R19 Wrangler Duratrac would have landed me in the dog house on appearance and noise.

I think that is the best solution 19" tire.
