I have the Sedona Rock a Billy's 28x10x14 on Raceline Scorpion wheels 14x7 w/5+2 offset and love them so far! They are a radial and ride awesome down the road. I have really lost no power or top speed. Still hit 65mph with basically full cab but soft doors. I have not made to any real off-road stuff besides bombing through corn fields and snow drifts but they don't seem like they will disappoint me when I get to the parks either.
