I have bilsteins 5100's all around on my truck, on the highway they are great very smooth but on nasty bumpy roads you will feel it but for a truck I don't think its that bad. As for tires I have BFG TA KO2's on my truck and I love them. Great traction all around so far and ive done wet, dry, sand, dirt, have also towed with them and they have not let me down yet. I think I got my set for about $1100 OTD at Americas tire when they had a special. Noise on these things is minimal too which is a big plus for the wifey since she hated how noisy my last set of tires were (Nitto's).
