i've read several places that these ratings differ between manufacturers, and should only be used within the same brand name to compare tires. if they are used between brands, they should only be used as a rough estimate.
is there truth to this?
As far as I know, the ratings such as UTQG, heat, traction, are all government stuff done under very specific curcumstances. So they should be a decent relative comparison across all brands... but, the grades are basically "Excellent" "Good" "Decent" "Not Quite So Good" "Not Great"... so take it for what it's worth. UTQG is probably the most useful number, the other two you could pretty much tell just by looking at the tire as to what it was intended for and what it'll probably take.

"420" treadware :rofl:.
better traction and practically same treadware.
what a tire.
The 420 "should" have a higher traction rating the a 460, unless the tire is better at doing something other than the government test. The "AA" traction rating doesn't really mean all that much in the real world.
My Michelin Pilot Sport PS2's (220 UTQG) appear to be a regular street tire, but have an AA traction rating. An RT615 looks like a near-slick and has an A traction rating. I'm sure the RT615 (200 UTQG) probably does something better than the PS2's, but I don't know what that something is... other than cost ALOT less :biglaugh: I'd rather have the michelins in the rain, I'll say that much.
Reading reviews from a large selection of people who've driven on the tires is a good indication of how they work in extreme conditions. It's usually fairly easy to see through the bullshit and the half-wits too. Tirerack is great for reviews.
BFG tires are generally packed full of win... I've hardly heard anyone complain about any of their tire lines. My next tires for my truck will be BFG A/T
