Dry roads, and the track.

KDW z rated tires have a 400 tread wear and the FZ4 have a 300 which means there rubber is softer and will grip the road better on dry roads. I tried driving on some light snow with my kdw and they sucked. And all the rating are the same except for the tread wear. With the goodrich all you paying for is the brand name and all the over head from the stores that carry them.

Bull****. A lower treadwear does not mean a softer tire AND less grip. The KDW has a treadwear rating higher than my Yok AVS-i, and more grip.
Come to think of it, the KDW has a treadwear of 300, not 400. The KDWS has 400 and is an all-season tire with less dry grip than the KDW. Significantly different tire. If you had expreiences with the KDWS, then I understand your POV. But the KDW is a far superior tire to the Toyos.

Now the GSC that use to come on the svt back in 98 had a far better grip the the KDW. The only reason they switch was because the gsc wore out too quick and the KDW has a bit better wet road traction.
Again, reenforces my KDWS assumptions. Goodyear hasn't made a true performance tire that competes on the street with the others. SVT switched to BFG for the Contour because the GSC's rode like a rock and had little grip.
With todays compounds and rubbers you could pick almost any zrated tire and have it perform as well as any other. Both the fz4 and kdw along with almost all the other name brand zrated tires ahve a AA rating in traction and a A rating in Temp. The treadwear is the only thing that is different in most of these tires. I dont run fz4 on my tour i run the t1-s and they would smoke the kdw.
Another mistake. Just because two tires have the same UTQG rating, does not mean they will perform the same, on dry, wet, snow, wherever. Differences in compound and tread pattern make such a huge difference. Not all Z rated tires perform the same. Check out
www.tirerack.com for the tire tests or this link for the KDW.
http://www.tirerack.com/tires/tests/bfg_gforce_kd_rd.htm If you are happy with your tires, good. But I doubt they are better than the KDW in anything except noise on conctrete roads. Snow? The KDW is not designed for it so who cares? I didn't drive on them in the snow. If you need an all-season tire, there are other options, like the KDWS.
