Those Special Service Swampers are sweet, I was considering them until I decided I needed a 35" or 35" TSL instead. I like the pizza cutter look and performance on a 2.5L jeep.
I went with the Q78 TSL, it runs about 35.5"x10" and is the same height as the 36" TSL's but has more tread depth, 27/32".
I run my TSL's on the road a few hours at a time to the trailhead, they do pretty good. I did the internal balancing with Dynabeads and it works great.
