Tire traction and other things

[Rhyder]

I originally posted this on a recommendation thread, but got to thinking, I really do want the answer, am I missing something?

I've heard that the higher the UTOG the less traction(stickiness) you get....

Whats that mean in realistic terms?

as an example, taken from the list.

you have a high UTQG:

Nitto Motivo = UTQG: 560 A A (All Season)

and a low UTQG:

Perilli P Zero = UTQG: 220 AA A (Summer Only)


They both have an A temp grade which means they are rated at "Over 115 MPH" the highest rating. Way fast enough for everyday use.

Where they differ is the A traction and the AA traction. the first and second highest rating.

Traction:

_____________Asphalt G force____Concrete Gforce
AA---Above-------0.54---------------0.41
A----Above-------0.47----------------0.35

So when you state the higher the UTQG the less sticky it is, you are technically correct. But it appears to me going from one extreme to the other on the list, and as most roads are asphalt, your talking a difference of .07 G force difference between the two.

Is that even really measurable? I mean if you were doing the road Atlanta race, maybe, but who drags or races seriously with regular tires?


It seems to me to be basically propaganda to get us to accept buying tires that wear out quicker, replacing them more often, and paying more for them, when the longer lasting and cheaper ones are just as good for all practical purposes.....you have to have the best of the best right?


I may be missing something, I'm in no way a tire engineer, I'm simply going off the charts provided.


below is the graphs I used:

Copied from RickRay's post:

If your going for the most Tread Wear(more Life) then it has to have a larger UTOG:IE:
TREADWEAR: 220
TRACTION: AA
TEMPERATURE: A

Nitto Motivo = UTQG: 560 A A (All Season)
Nitto Invo = UTQG: 260 A A (Summer Only)
Gmax as-03 = UTQG: 480 A A (All Season)
Falken 452 = UTQG: 300 AA A (Summer Only)(Front Original Size Only)
Perilli P Zero = UTQG: 220 AA A (Summer Only)
Hankook Ventus V12 evo K110 = UTQG:280 AA A (Summer Only)
Goodyear Eagle GT = UTQG: 400 AA A (All Season)
Firestone Firehawk Wide Oval AS = UTQG: 400 A A (All Season)
Continental Extreme Contact DWS = UTQG: 540 A A (All Season)
BFGoodrich g-Force Sport COMP-2 = UTQG: 340 A A (Summer Only)
Cooper Zeon RS3-S = UTQG: 300 A A (Summer Only)
VREDESTEIN ULTRAC SESSANTA = UTQG: 280 AA A (Summer Only)



Heres the link I got the specs from....
