KDW2 (KDW NT) vs. GS-D3

i haven't had the KDW's yet but my GSD3's are insanely good in wet and all around traction...both tires get rated well around here.

I have the KDWs with the traditional tread... they seem to grip pretty well in the rain, and on the dry pavement. I will say, they are kind of loud though, but I'm not sure if thats an issue that has been resolved with the new tread design.

$814 BFG's vs. $1,002 for GSD3's

$188 difference or ~$47 per tire. If the GSD-3's are that much better of an all around tire then I think it's worth it, but they will have to outlast the BFG's and with a 280 treadwear vs. BFG's 300 I don't think they will.

you can actually hear tire noise over your exhaust? Something isn't right with this picture... I can barely hear my radio

You CANNOT compare Treadwear ratings from one brand tire to another. That is not a government controlled rating. You can only compare GY to GY, BFG to BFG and so on and so forth. They make the number system up for how their tires are going to rate compared to another tire in their line up.

The Traction and temp ratings are controlled so those are comparable.

Treadwear Grades

UTQG Treadwear Grades are based on actual road use in which the test tire is run in a vehicle convoy along with standardized Course Monitoring Tires. The vehicle repeatedly runs a prescribed 400-mile test loop in West Texas for a total of 7,200 miles. The vehicle can have its alignment set, air pressure checked and tires rotated every 800 miles. The test tire's and the Monitoring Tire's wear are measured during and at the conclusion of the test. The tire manufacturers then assign a Treadwear Grade based on the observed wear rates. The Course Monitoring Tire is assigned a grade and the test tire receives a grade indicating its relative treadwear. A grade of 100 would indicate that the tire tread would last as long as the test tire, 200 would indicate the tread would last twice as long, 300 would indicate three times as long, etc.

The problem with UTQG Treadwear Grades is that they are open to some interpretation on the part of the tire manufacturer because they are assigned after the tire has only experienced a little treadwear as it runs the 7,200 miles. This means that the tire manufacturers need to extrapolate their raw wear data when they are assigning Treadwear Grades, and that their grades can to some extent reflect how conservative or optimistic their marketing department is. Typically, comparing the Treadwear Grades of tire lines within a single brand is somewhat helpful, while attempting to compare the grades between different brands is not as helpful.
