How are they being used? I have the PJ's and have been very pleased with them. I don't use my truck for daily driving but more for off-roading and the performance of the PJ's has been GREAT. I can see how the wear with lots a street use could be an issue.
Perfect option and one I'm working on now myself is to have two sets of tires. GSA's for street and PJ's for off-roading.
Funny thing is I don't recall seeing anyone running BFG's on an H1 around here. Wasn't all that impressed with them on the H2 either. I can see this being a much better balanced tire between full off-road (Swampers and PJ) and a street tire (GSA's) though.
Let us know your impression should you go with the BFG's
