My vote is for BFG's. I've got the KDW's and they have been many times better than what I've owned before: stock 17" goodyear Z45's and sumitomo's. I have about 20,000 miles on the current BFG's and I expect to get another 10K out of them.
Pro's for the KDW
1. Excellent treadwear
2. Excellent rain traction (not a single scary moment yet, unlike the dozens befoe)
3. Dry traction is great, but I've heard that others may hook a little better from dead stop.
4. Handling overall was improved just by using this tire. I feel a lot more confident with the increased grip.
5. Few tires look this good.
6. Road noise is as expected, but the new X-pipe took care of that.
I give these high marks, because I only do street driving. If I were to race, track, or strip, then something else would probably be a lot better. But for everyday driving and the quick romp on curvy roads, these are great.
I run 255/45's right now, but the next set will probably be 245/45 so that the odometer will be dead on. Plus, I don't think there's much or any benefit with this non-stock size tire. I'm borrowing an 03 Mach 1 with 245/45's and it handles like a dream with the stock rubber (suspension is better than mine, but that's going to change soon).
